Publisher: 2009Dissertation note: The study was conducted to determine the infection rate of helminths in peafowl and to evaluate the comparative efficacy of two different broad spectrum anthalmintics.
For this puiose, eighty seven different breeds of peafowl like Blue peafowl, Java green peafowl, White peafowl, Black shoulder peafowl, Emerald peafowl and Pide peafowl of different ages, both male and female were selected which were present at Lahore Zoo. Faecal samples of 87 birds were collected in clean polythene bags, properly labeled and examined for the identification of helminths in the laboratory of Clinical Medicine & Surgery department, University of Veterinary & Animal Sciences Lahore. Faecal samples were examined by direct smear and centrifugal floatation methods for qualitative examination. For quantitative examination McMaster Egg Counting technique was used.
Moreover, chemotherapeutic trials were conducted by making four groups of birds. Albendazole (Methyl [5-(Prophylthio)-IH-Benzimidazole-2-yl] carbonate) (Selmore Pharma) at the dose rate of O.lml per k.g. of body weight in drinking water and Pyrantel Pamoate (1 Methyl-2-(2[2-thienylj-l, 4, 5, 6-tetrahydropyrimidine, 4, 4-methylenebis (3- hydroxy-2-naphthoic acid) (Pfizer) at the dose rate of O.lml per k.g. body weight oral suspension only once in the experimental trial was used and there percentage efficacy was determined. Drugs were administered orally to each bird using crop needle.
After the collection and laboratory examination of pre-medicated eighty seven faccal samples, the positive birds of different breeds of peafowl were divided in to three equal groups that were A, B and C. Forty nine out of 87 birds were positive for single or mixed infection of Heterakis gallinae, Ascaridia gaul, Davenia pro glotina, Capillaria columbae and Acuaria spiralis with there individual percentage was 36.73%, 26.53%, 6.12%, 18.37% and 12.24% respectively. Out of 49 birds 48 positive birds were divided in groups, each group consisted of 16 birds respectively. Group 'A' consisted of (Blue peafowl, Java green peafowl, White peafowl, Black shoulder peafowl and Emerald Peafowl, Pide peafowl). Group 'B' consisted of (Blue peafowl, Black Shoulder peafowl, Emerald peafowl and White Peafowl, Java green, Pide peafowl). In group 'C' birds included were (Blue peafowl, White peafowl, Pide peafowl and Black shoulder Peafowl, Emerald peafowl). While in group 'D' (White peafowl, Java green peafowl, Pide peafowl
& Blue Peafowl) only uninfected and untreated birds were kept.
Drug therapy was only induced to group A i.e. Albendazole 0.lml/kg body weight and group B Pyrantel pamoatc 0.lml /kg body weight, while infected but untreated birds were placed in group C.
The overall prevalence of gastrointestinal helminths in different breeds of peafowl pre-medicationwas found as 56.32 %. While the healthy birds were 43.68%. Faecal egg counts were again carried out on day 03, 07 and 10 post-medication and percentage reduction of EPG calculated. On day three the percentage efficacy of Albendazole was 44.76%, on day seven 73.01%, and on day ten 94.92% respectively. In the same way percentage efficacy of Pyrantel pamoate on day three was 29.27%, on day seven 50.13% and on day ten 78.34%.
The percentage EPG rise up to 3.75%, 6.24% and 6.99% at day 03, 07 and 10 in untreated group C was observed. While no infection was observed in group D through out the experimental study. In the current study no mortality of peafowl was found so no postmortem examination was conducted. There was no any side effect of Abendazole and Pyrantel pamoate was found in both the groups which were A & B respectively.

Publisher: 2005Dissertation note: The present project was designed to study the prevalence of lice infestation in pigeons and to study the efficacy of Ivermectin against lice infestation in pigeons.
A total of 300 pigeons were examined to study the prevalence of lice infestation in domestic pigeons in different localities of Lahore (pigeon owners and aviaries) during the month of April, 2004. Out of 300 birds examined 271 birds revealed lice with an overall incidence of 90.33% of lice infestation.
Permanent mounts were prepared from specimens collected from different birds. On the basis of morphological characters and taxonomical features the specie of lice identified was Columbicola columbae (Slender Pigeon Louse).
The efficacy of Ivermectin was determined on the basis of reduced number of lice from the body of pigeons in group A, B and C, group D served as untreated infested control and group E served as healthy control group. Birds were examined on days zero, 3, 7 and 10 of the experiment. On day 10, efficacy of Ivermectin was 91.66%, 75% and 83.33% in group A, B and C respectively.
Haematological examinations were made to compare the blood picture of infested birds treated with Ivermectin , infested birds kept as control and healthy control birds. Blood parameters studied were: Haemoglobin Estimation and Differential Leukocytic Count. The results of haematological examination showed a significant increase in haemoglobin level of birds treated with Ivermectin, there was a significant decrease in differential leukocytic count of treated birds.
The values thus recorded were analyzed statistically using computer program MSTAT.

Publisher: 2013Dissertation note: Toxoplasmosis is a parasitic zoonosis with worldwide distribution caused by Toxoplasma gondii and is demonstrated in domestic livestock, wild life, other animals and humans. Keeping in view the zoonotic importance of the disease, the current study was conducted to find out the epidemiological status of toxoplasmosis in camels and human population in Cholistan desert area of Bahawalpur and to determine the possibility of transmission of toxoplasmosis from camels to their owners.
Serum samples from camels (n=226) and humans (n=113 camel owners and n=113 people having no contact with camels) were collected and analyzed by using Latex Agglutination Test (LAT) to determine the prevalence of Toxoplasma gondii in camels and humans.
Overall 9.73% camels were seropositive for anti-toxoplasma antibodies. In the month of April camels had the high prevalence of 11.5% (9 out of 78). . The highest prevalence (12%) was determined in the camels having age of 11 years or above. The prevalence of toxoplasmosis was high in the third trimester of pregnancy (27.2%). Although, the difference in prevalence of T. gondii infection was significantly different (P<0.05) at pregnancy of she camel. Overall 27 (12%) humans were seropositive for anti-toxoplasma antibodies. The highest prevalence of toxoplasmosis (15.25%) was detected in the people in 30-40 years or above age group. The highest sero-positivity was observed in camel owners (15.92%) and the lowest sero-positivity (7.96%) was observed in the people having no contact with camels. However, the difference in prevalence of T. gondii infection was significantly different (P<0.05) at the contact of humans with the camels.

Publisher: 2014Dissertation note: Dengue fever is one of the most common mosquito-borne viral diseases of human beings. It has become a major reason for public health concern internationally over the recent years because of disease morbidity and mortality. Globally around 2.5 billion people are living in areas where dengue viruses can be transmitted. Spread of mosquito vectors & viruses in geographical distribution are two main reasons of rise in incidence and prevalence of dengue fever & appearance of dengue hemorrhagic cases. Urban areas of the tropics have been identified to be highly endemic. According to estimates made by WHO around 50–100 million infections of dengue are prevalent every year globally. (Deen et al. 2006) In Pakistan first dengue outbreak was reported in Karachi in 1994 as environmental conditions are conducive to Aedes mosquito breeding. Economic and security related migration introduced virus to Lahore as well. According to Punjab Health Department 590339 suspected cases were reported in Lahore & 21685 confirmed by serology. It has been observed that 5-10% of these cases develop DHF.(Mahmood et al. 2013)
Dengue is mainly transmitted by mosquito vector i.e. Aedesaegypti and can also be transmitted by A.albopictus to a lesser extent. Virus that causes dengue has four different types that are closely related to each other.Infected female mosquitoes transmit this virus to human beings through bite.An infected mosquito can transmit this virus to humans for the rest of its life. Symptoms of dengue range from very mild fever to very high fever including intense headache, retro-orbital pain, muscular and joint pain, and rashes. There is no vaccine or any specific medicine to treat dengue. Patients having dengue fever are advised to take rest and drink ample fluids. They are advised to use paracetamol in order to reduce high grade fever or visit the physician if fever persists. Recovery from infection by one provides lifelong immunity against that serotype but confers only partial and transient protection against subsequent infection by the other three. There have been enough proofs showing that subsequent infection increases the risk of severity of disease which can result in DHF (WHO).
Leaking of plasma, fluid accumulation, respiratory distress, and intense bleeding and organ impairment makes severe dengue a fatal complication. Warning signs includes decrease in temperature (below 38°C/ 100°F), severe abdominal pain, rapid breathing, bleeding gums, malaise, and restlessness,continuous vomiting and hematemesis. These can occur three to seven days after first symptom recognition. In order to prevent complications and minimize the risk of death adequate and timely health care is required in next 1-2 critical days.(Halstead 1980)
In 1950s when dengue epidemics occurred in the Philippines and Thailand then Dengue hemorrhagic fever was first identified. Till 1970 nine countries had encountered epidemic DHF and this number has increased more than four times and keeps on rising. Today rising number of DHF cases are causing increased dengue outbreaks in the Americas, and in Asia, where all four dengue viruses are endemic. DHF has turn out to be a prominent reason of hospitalization and demise among kids in several states.In Asia, widespread DHF has enhanced geologically from Southeast Asian regions to west China. Various regional states of the South and Central Pacific have encountered significant or slight DHF outbreaks.In previous twenty years deterrence and management has come to be more immediate with the escalating geographical spreadof dengue and dengue hemorrhagic fever and higher ailment occurrence (Gubler 2002).
In the absence of bleeding or organ manifestation, DHF is medically challenging to diagnose, and the numerous etiologic agents can barely be distinguished by clinical tests. The specified diagnosis of DHF depends mainly on laboratory testing.(Drosten et al., 2002)

Publisher: 2015Dissertation note: Poultry industry is the most effective and economical source of animal protein. Because of increasing future demands, poultry industry is unable to narrow down the animal protein supply and demand gap. Poultry producers are looking forward for using the alternate source of chicken meat, which in the future will come from pigeon and quail meat. It will be very help full for increasing gross domestic production (GDP) through livestock sector (Basit et al. 2006).
Pigeons have been domesticated to live close with human beings. Pigeons originate from the rock dove in Europe, have been partially domesticated and carried to all parts of the world. Pigeons have been divided into three groups.
1) Poultry pigeons
2) Carrier and racing pigeons
3) Fancy and feral pigeon
Pigeons are easily bred to produce a variety of plumage or to provide squabs for the table (Basit et al. 2006).
It is very well known that internal parasites cause great loss to the host, by different ways. These parasites live at the expense of host depriving them from the nutrients essential for their growth. Moreover they cause mechanical harm by producing inflammation and tissue damaged. Protozoa inhabiting the digestive tract of birds are responsible for considerable economic losses. Heavy infestation of the parasites affect the health of birds with loss in the body weight, retarded growth, unthriftiness, damage to the gut epithelium, fertility disturbances, emaciation and death especially in young birds (Urquhart, 1996).
Introduction

Common name of Trichomonas gallinae is canker, frounce and roup. Predilection site of this parasite is esophagus, crop and proventiculus. It belongs to the family Trichomondidae and class Zoomastigophorasida (Taylor et al. 2007).
Body of T. gallinae is elongated, ellipsoidal os pyriform. Its size is 5-19 × 2-9 μm. It has four anterior flagella that arise from blephroplast, having undulating membrane that does not reach the posterior end of body and free posterior flagellum is absent. Its axostyle is narrow and protrudes 2-8 μm from the body and its anterior portion is flattened into a spatulate captulum. Its parabasal body is hook shaped and parabasal filament is present (Taylor et al. 2007).
The host of T. gallinae is pigeon, turkey, chicken and raptors (hawks, falcons and eagle). As the method of reproduction is concerned it reproduced by longitudinal binary fission. There is no sexual stages and cyst are present in its life cycle. Lesion present in the turkey and chicken are most commonly in the area of crop, oesophagus, pharynx and no lesion are found in mouth (Taylor et al. 2007).
Size of trophozoites of T. gallinae is about 7-11 μm. Its shape is varied from oval to pyriform. It has four flagella and a fifth recurrent one, which did not become free at the posterior pole. Size of nucleus is about 2.5–3 μm, oval in shape and situated closely below the basal bodies of the flagella. Its axostyle consisted of a row of microtubules that is running from the region of the apical basal bodies to the posterior end of the cell (Mehlhorn et al. 2009).
Infected pigeons show wild signs of depression, lose weight, stand huddled with ruffled feathers and may fall over when forced to move. There is an accumulation of greenish fluid present in the mouth and crop containing large number of trichomonads in it. Yellow, necrotic lesions are present in the esophagus and crop (Taylor et al. 2007).

Trichomonas gallinae is a causative agent of trichomoniais in birds. It affects mostly to the young birds and causes death in them, especially in pigeons within 10 days. This Protozoa is present in the gastrointestinal tract of birds and causes greater financial losses. Clinical sign of diseased birds are dull, depress and having yellow color diarrhea. Morbidity rate of this disease is high in birds. If infected birds are not treated, it causes high mortality in diseased birds, due to this reason this problem become very important. Trichomonas gallinae presents in upper digestive system and respiratory system. So it affects both digestive system and respiratory system. It is mainly found in pigeons, but turkey, chicken, hawks, mourning doves, golden eagles, falcons and bustards may also be infested with this protozoa (Saleem et al. 2008).
Small, whitish to yellowish caseous nodules are found in the esophagus, pharynx and crop. Their size increased and may remain circumscribed and separate, or may become thick, caseous, necrotic mass present in lumen. The circumscribed disk shape lesion are known as yellow buttons. Size of nodule is 1 cm or more and found in liver, lungs and other organs (Taylor et al. 2007).
Infection spread to turkey and chicken by drinking contaminated water. The pigeon and other wild birds are also source of infection, which also use the water source. T. gallinae enters in the water through mouth and not from feces of the wild birds. Source of infection is direct contamination because this organism is very sensitive to drying and no cyst are found (Taylor et al. 2007).
There are more chances of trichomoniasis in young one than in adult pigeons. During feeding carrier pigeons transmit this disease to their young ones. The pathological lesions associated with trichomoniasis is inflammation, ulceration, and necrosis in nature. These lesion are more predominant in the oral cavity, esophagus, crop and proventiculus (Kennedy et al. 2001).
Introduction

This disease is present worldwide. A clonal strain of previously described organism has been recently developed as the cause of widespread disease of birds in Europe and causes a grate economic losses (Ganas et al. 2014). In Britain, this infectious disease was first described in 2005. This disease causes significant mortality in birds which results in decreased population of green finches and passenines (Robinson et al. 2010).
T. gallinae affects upper digestive system of birds and results in pathological changes in structure of different parts of digestive system. It causes slight inflammation of mucosa to large caseous lesions of esophages. These lesion sometime block the lumen of esophagus. Due to this secondary infection of parasites, bacteria and virus takes place in diseased birds. Different strains of parasites move toward other organs such as liver, air sacs, lung, and brain. They causes necrosis of these organ, which leads to the death of birds (De Carli et al. 2002).
Prevalence of T. gallinae infection is different in different age of birds. Prevalence increased with the age of nestling (Krone et al. 2005). A higher prevalence of Trichomoniasis has been recorded in pigeons in Pakistan season wise prevalence has been recorded to be 43%, being non significantly higher in April (56%) than in March (30%). Trichomoniasis positive cases show a significant decrease in hemoglobin concentration, number of monocyte, packed cell volume, body weight than healthy birds (Saleem et al. 2008).
T.gallinae is a parasite of different species of birds ranging columbiformes, diurnal raptors and captive gallinaceous birds. It causes stomatitis, esophagitis and ingluvitis (Bunbury et al. 2007).
This disease is recently emerged in British passerines. This parasite has caused high mortality in finch and their population is decreased and this disease is also spread to continental Europe (Chi JF 2013).
Introduction

The sequence of T.gallinarum is different from Tetratrichomonas gallinarum that is another trichomonad of birds, but it is genetically similar to Trichomonas Caninistomae that affect dog and cat and causes oral infection. Pigeons are prey of dog, so there is possibility that T. gallinae may have infected (carnivorous) mammals in the past (Gasper et al. 2007).
This disease causes large economic loss of avain livestock and also cause problems for wild species of birds. In UK T. gallinae has caused the death of greenfinches (Lawson et al.2006). Trichomoniasis was first reported in 2005 in Britain. It was discovered in finches. It caused large scale mortality in finches with population decline (Robinson et al. 2010; Lawson et al. 2011). In 2007 this disease is reported in finches in the Canadian Maritime provinces, southern Fennoscandia and northern Germany (Lawson et al. 2011). This disease caused high morbidity and mortality in finch population in Britian. It is estimated that about 1.5 million greenfinches which represent the 35% of national population have been died with this disease (Lawson et al. 2011).
In this disease multiple foci of caseous necrosis is seen in oral, esophagus and crop mucosae. There is heavy infiltration of inflammatory cells especially heterophill in these areas. There is multiple foci of necrotic inflammation is seen on liver. Due to excessive infiltration of heterophils in there is thickening of mucosa of easophagus. Necrotic material is also seen in mucosa and submucosa of easophagus. There is necrosis on the tip of villi of intestine and necrotic materials is seen in the mucosa of intestine (Al Sadi et al. 2011).
Trichomoniasis occurred more frequently in young than adult pigeons. High prevelance of trichomoniasis have seen in male than female pigeons (Al Sadi et al. 2011). Nestling birds are more susceptible to this disease than other birds. In Tucson, Arizon study was conduct and this study show that T. gallinae was present in oral cavity of 85% nestling coopers hawks compared to
Introduction

only 1% of breeding age hawks. This disease is more prevalent in young pigeons. T. gallinae is sensitive to environmental pH. Trichomonas gallinae develop well when pH is between 6.5 and 7.5 (optimum 7.2), but cannot survive in more acidic pH. In fledgling and breeding Coopers Hawks pH of their oral cavity is acidic, so they are less susceptible to trichomoniasis and this is very important in differential prevelance among age group of birds (Urban et al. 2014).
Trichomonas gallinae changes the blood picture of infected birds. It causes decreased values of Hb, PCV and monocytes in infected pigeons than the healthy pigeons, while TLC, heterophils, lymphocytes and eosinophils are increased in disease pigeons than the healthy pigeons (Seddiek et al. 2014).

Publisher: 2015Dissertation note: Brucellosis is among the vital zoonotic and transmissible bacterial diseases of most of the animal’s worldwide (Shafee et al. 2011). Various types of brucella species are the causative agents of bovine brucellosis. In bovines, brucellosis is mainly triggered by Brucella abortus, less repeatedly by Brucella melitensis and sometimes by Brucellosis suis. As it is a zoonotic disease so, the public health is near thoughtful risk. According to (Pappas et al. 2006), it is considered to be the collective zoonosis worldwide, moreover 5, 00,000 cases of brucellosis are reported annually in both animals and humans. It is a common problem of under developed countries with poor health programs. This disease has been eradicated from USA, Canada, Japan, and New Zealand however; it is still an uncontrolled hazard in highly endemic regions of Africa, Latin America, Middle East and Asia (Refai, 2002).
According to Food and Agriculture Organization (FAO), World Health Organization (WHO) and Office International of Epizootics (OIE), brucellosis is considered the most wide spread zoonosis in the world (Schelling et al. 2003). The infection transfers via contact with the body secretions, aborted fetus, contaminated milk feeding, licking of aborted fetuses and also venereal disease. In animals, reproduction, fertility, reduced survival of newborn, decreased milk production and noticed able mortality of the adult are the main effects of brucellosis. (Al-Sous et al. 2004).
It is characterized by abortion during 3rd trimester of pregnancy, weak calves, still births infertility, placentitis, epididymitis, orchitis and the excretion of organisms in milk and uterine secretions. According to public opinion brucellosis is work-related disease it has more effects on

Veterinarians, slaughter house and farm workers likely butchers and shepherds (Yagupsky and Baron 2005).
Brucellosis occurs in cattle, Sheep, goats, swines, camels, dogs and it may also affect the other ruminants and marine mammals. The other names of brucellosis are Enzootic abortion, Contagious abortion, Bangs disease, Undulant, Malta and Mediterranean fever. It also causes significant losses in those animals which are sexually matured (Forbes and Tessaro 1996).
The main causative agent of bovine brucellosis is Brucella abortus (Ali et al. 2014). The animals and persons, who are directly or indirectly in contact with infected animals, its products and by-products, may acquire infection easily. The main source of human infection is the raw milk of the infected animal as it excretes brucella in milk (Shimol et al. 2012). The Serological, Bacteriological and Molecular Methods are used for the diagnosis of brucellosis in the farm animals and humans. Bacteriological method is considered to be the most standard method among all of the above mentioned methods (Sathyanarayanan et al. 2011). However, due to non-availability of ‘BSL-3 laboratory’ for culturing and isolation, time taking nature and because of the safety concerns of the laboratory workers, it is not widely applicable. According to Alton et al. (1998), in Pakistan, at animal and herd level, the molecular tools, like ‘Polymerase Chain Reaction’ (PCR), are not economical for screening due to limited resources. ‘Milk Ring Test’, a serological test, is economical and mostly used for the diagnosis of brucellosis however according to Huber and Nicoletti et al. (1986), its specificity and sensitivity is doubtful even now.
In most of the countries, for the control and eradication of the disease the serological diagnosis is widely used. Although, different techniques are used to detect the brucella antibodies but, different antibody isotopes were detected by each one of the technique to

determine seropositive animal to brucellosis (Nielsen et al. 2001). The serological test is more sensitive as compare to the culture techniques but its specificity was quite low (Al-Attas et al. 2000).
Diverse studies have been conducted worldwide to evaluate different brucella diagnostic techniques. ELISA was found more sensitive and specific as compared to other serological techniques and the findings confirmed that standard tests, like Rose Bengal Plate test (RBPT) and Serum Agglutination Test (SAT) only detect antibodies to the LPS (lipopolysaccharides) antigen of Brucella abortus so, it has low specificity (Al-Attas et al. 2000). The advanced in specificity and sensitivity levels of the ‘Serological Diagnosis’ as compared to the other conventional technique are due to the introduction of the indirect immuno-enzymatic technique (Mousing et al. 1997).
The indirect ELISA uses cytoplasmic proteins to measure the immunoglobulins of classes M, G, and A. The clinical situation can thus be interpreted better further it also overcomes some of the short comings of serum agglutination test. A comparison shows that ELISA is more specific and sensitive than SAT (serum agglutination test) Almuneef and Memish (2003).
According to certain studies conducted worldwide and also in Pakistan, it has been proved that ELISA tests are more accurate and reliable than other tests like Serum Agglutination Test (SAT) and Milk Ring Test (MRT), showing high seropositive samples. Shafee et al. 2011 confirmed by using i-ELISA for the prevalence of brucellosis in Quetta city and the result was found to be 3 and 8.5 percent overall prevalence in cattle using MRT and indirect ELISA respectively.
The Gilgit Baltistan is at developing stages in the livestock sector, small farmers owning 95% of the Gilgit Baltistan’s livestock and are landless, providing an opportunity for improving

the quality of their livestock. The areas selected for the study were the villages (Shagaribala, Shagari kalan, Kathpanah, Chunda, Kachura, Hussain abad and Sadpara) of Skardu district, which are very important from livestock point of view. There is a dire need of screening these animals for the zoonotic point of view. It is the first time that effort for the diagnosis of brucellosis in Gilgit Baltistan by using the serological test like Rose Bengal Plate Aggulutination Test (RBPT) and Indirect Enzyme Linked Immunosorbent Assay (ELISA) has been made.

Publisher: 2014Dissertation note: Pakistan being an agriculture country has 70% of its population that is totally dependent on agriculture and livestock sector which plays an important role in the economy of the country. Livestock has contribution of about 55.4 percent to the agricultural value added and 11.9 percent to the National GDP. Pakistan has population of about 64.9 millions of goat, 38.3 millions of cattle, 33.7 millions of buffaloes and 28.8 millionsheep population according to the economic survey estimate. Mutton production is about 643 million tons and beef production is about 1,829 tons out of total 3,379 million tons of meat production. Livestock produces approximately 49,512 million tons of milk out of which buffalo produces 62.0% while cattle produces 35% and sheep-goat produces 1.69% (Economic Survey, 2012-2013). Pakistan is the 3rd largest milk producing country in the world (Afzal, 2010).
Diarrhea can be defined as an increased in volume and quantity of fecal excretion. The diarrhea may contain mucous, blood, poor odor and variation in color then the normal feces.On the basis of time period, diarrhea has different types likeacute, constant and chronic. Time Period of acute diarrhea is not more than 14 days while in case of persistent/constant form, it continued for more than 14 days and in chronic case the diarrhea remain for a time period of 28 days(Bazeley, 2003)
Diarrhea is a leading factor towards the death of calves. Neonatal calf diarrhea is among the very important diseases of the calves worldwide. It is animportant contribution to the major economic losses in cattle industry. The cause of calve diarrhea may be infectious or non-infectious (Elhassan et al. 2011).
Bad hygiene, overpopulation, overfeeding, hot/cold temperature, feeding the calves artificially and the colostrum’s deprivation are all predisposing factor in the complex etiology of the disease (Hemashenpagam et al. 2009).
Infectious agent and the co-infection of different multiple pathogens are common in calves having diarrhea. Rotavirus, Cryptosporidium, corona virus and enterotoxigenicE. coli collectively are associated with 75-95% of the infections in calf diarrhea around the world. Clinically, Neonatal calf diarrhea is characterized by profuse acute watery diarrhea, progressive dehydration, acidosis and death within a few days. The degree of dehydration is estimated by the physical examination of calf and has been introduced as a reliable method (Radostits et al. 2009).
Experimentally the intestinal potassium and sodium combination can be bothered by different causes and various types of factors. However, electrolytes that are built up in the gastrointestinal tract have a function to reduce the water assimilation. Due to this, the organism losses water and the electrolyte commonly (Smith, 2009)
To evaluate the serum electrolytes as well as the acid-base imbalance, there is a need of laboratory tests which cannot be measured regularly in field condition.To check the degree of dehydration is a uniform protocol and is anticipated by body condition score of calves (Naylor 1989).
The electrolytes deficiency in neonatal diarrheic calves might be the cause of death in some cases. Althoughit is understood that serum concentrations of potassium (K) and sodium (Na) are very much necessary with reference to the fluids composition used for treatment purpose (Rucker et al. 2008).
Trace elements have also important part inthe reproduction, growth and productivity of the householdanimals. The imbalance and Difference in ratio of minerals leads towards both production and economic losses throughout the world. The important symptoms of trace element deficiencies that can be clinically shown in animals are anemia, diarrhea, loss of hair, pigmentation loss, growth disorders in bones, difficulty during walking, a flaky deposit in skin, bending, hyperkeratosis, Para keratosis, lack of appetite, decrease in reproductivity and fertility, young animal growth disorders, Tetany, reduction in protein synthesis, immunity compromised calves, abortion related to non-infectious factors and pica. However, reduction in the concentration of trace elements like cobalt, copper, iron, iodine, manganese, selenium or zinc leads to lower reproduction rates and lactation. Untreated changes in the serum concentrations of Ca, Mg and some trace elements may be the root of cause of some death or post diarrhea complications such growth retardation (Tajik and Nazifi, 2012).
The serum values of calcium (Ca) and magnesium (Mg) that is abnormal persists for a significantly long duration after the treatment of neonatal diarrheic calves. The normal serum concentration of Ca in cow has been reported as 2.43-3.1 mmol/L while the mean serum Ca in diarrheic calves reported was 1.297mmol/L. The normal serum concentration of Mg in cow has been reported as 0.74-0.95 mmol/L while the mean serum Mg was reported to be 0.8145mmol/L (Kaneko et al. 2008).
There are many advantages of using the hypertonic saline solution (7.5% NaCl; 4ml/kg BW) in diarrheic buffaloes and cattle to resuscitate them. Infusion of Hypertonic saline solution resulted in significant increase in sodium and chloride level in serum. The important feature for the successful and complete resuscitation of hypovolemia along with endotoxaemia in diarrheic buffalo calves is the total amount of sodium. The infusion of Hypertonic saline solution is quite safer and it does cause hypernatremia but not for a prolonged period. So, hypertonic saline solution has advantage of resuscitating the calves from acidemia and hypovolemia. It was also helpful in the improvement of oxygenation and cardiovascular performance (Zafar et al. 2012).
The neonatal calf diarrhea can be cured by using the electrolyte therapy like ringer lactate, non-steroidal anti-inflammatory medicines and antibiotics in case of infectious diarrhea and through better farm management depending upon the root of cause (Radostits et al. 2009). There is a hypothesis that treatment of diarrheic calves with NSAIDs attenuates the behavior of sickness as well as gastrointestinal discomfort and encourages the calves to maintain an appetite supports the calves for better performance (Ghanem et al. 2012)

Publisher: 2015Dissertation note: Agriculture sector plays a pivotal role in the economy of Pakistan. At present it
participates 11.4% to GDP. Agriculture provides 45% employment to labour of our country
and contributes in the development of other sectors of the economy. The livestock sector
occupies a distinguishing position in the National Agenda of economic development. It
provides net source of foreign income. In the history livestock has been dominated by small
holders to meet their needs of milk, food safety and cash earnings on daily basis. Besides,
livestock is considered a source of employment generation at rural level. It plays an important
role in poverty mitigation and keeps in elevating the socio-economic situation of our rural
commonalities. Livestock share approximately 55.4 percent to the agricultural value added
and 11.9 percent to national GDP during 2013-14. Anonymous (2013-14).
Parasitism is one of the major problems lowering livestock productivity round the
earth Vercruysse and Claerebout et al. (2001). The significance of helminthes infections is
increased manifold in developing countries like Pakistan where 65.2% population is rural
(Population Census Organization (2007) depending upon livestock for their incomes and
where parasitism acts as a serious trouble for livestock economy Chaudhry et al. (1984).
Among helminthes infections, fasciolosis commonly called as liver fluke disease is of vital
importance due to its wider spectrum of ultimate hosts Rondelaud et al. (2001) causing acute
and chronic infections Sampaio-Silva et al. (1996). The disease is primarily caused by
Fasciola hepatica and Fasciola gigantica Soulsby et al. (1987). Fasciolosis is a parasitic liver
infection of wild and domestic ruminants caused by genus Fasciola, which has worldwide
distribution Soulsby et al. (1986). Fasciolosis causes economic losses as a result of
mortalities, abortions, retard growth, reduced milk and meat production, condemnation of
infected liver and emaciated carcasses and cost of animal treatment Gracey and Collins et al.
(1992). Fasciolosis caused by F. hepatica is a cause of important economic losses in
ruminants. The disease is widely spread throughout in Africa, Asia and the Pacific. Although
mostly a problem of young stock, the disease is also found in older animals where it
adversely affects health, growth rate and development. Apart from its great veterinary
importance throughout the world, fasciolosis caused by both F. hepatica and F. gigantica has
recently been shown to be a re-emerging and wide spread zoonosis affecting a number of
human populations Mas-Coma and Bargues et al. (1997); Esteban et al. (2003).
Prevalence of fasciolosis infestation in buffaloes is 49.01%. The infestation of
fasciolosis was optimal from January to September, while least during October to December.
Fecal samples indicated F. hepatica prevalence 65%. Whereas prevalence of F. gigantica
was observed higher in adult cattle as compared to cattle calves by fecal egg counts Khalil et
al. (2009). 4% Buffalo calves infested with trematodes. Availability of intermediate host and
the grazing habits of the final host determines the epidemiology and seasonal pattern of
infection with trematodes Pfukenyi et al. (2005); Bhutto et al. (2002). The life cycle of F.
hepatica includes many stages which develop in the environment or the intermediate host.
Metacercariae which is the infective stage encysted and ingested by grazing herbivores.
Temperature and rainfall are the important factors affecting the life cycle and the prevalence
of F. hepatica infection McCann et al. (2010). Many studies revealed that F. hepatica is
endemic in buffaloes, cattle, goats, sheep and humans in Pakistan Ijaz et al. (2009); Iqbal et
al. (2007); Khan et al. (2010) and Qureshi et al. (2005).
Fasciolosis is the disease by which about 250 million sheep and 300 million cattle are
potentially affected worldwide Boray et al. (2005), and more significantly infects all
ruminants Iqbal et al. (2007). F. hepatica and F. gigantica are the two liver flukes commonly
reported to cause fasciolosis in ruminants Walker et al. (2008). Infected cattle can exhibit

poor weight gain and dairy cattle have lower milk yield, and possibly metabolic diseases
Mason et al. (2004). Losses due to fasciolosis in the United Kingdom and Ireland alone are
more than ￡18 million a year Mulcahy and Dalton et al. (2001); €52 million a year or €299
per infected animal in Sweden Schweitzer et al. (2005); 0.26 million USD annual due to
fasciolosis associated liver condemnations in cattle slaughtered in Kenya Kithuka et al.
(2002). In Pakistan, 35697 USD (3141360 PKR) are reported in only one tehsil of Punjab
province, the Sargodha T.U. Rehman et al. (2013). While Fasciolosis is prevalent in whole
Punjab province of Pakistan but the marshy areas such as regions of Gujranwala, Lahore,
Multan, Faisalabad, Jhang, Muzaffargarh, Sheikhupura, and Sargodha are of major concern.
Fascioliasis in ruminants causes substantial economic losses, estimated at US$ 2
billion per annum worldwide, to rural agricultural communities and commercial animal
producers due to death of infected animals, condemnation of affected livers and production
losses associated with reduced feed conversion efficiency Urquhart et al. (1996); Spithill and
Dalton et al. (1998). In tropical countries, fascioliasis is prevalent up to 90% and is
considered the most important helminthes infection of cattle Spithill and Dalton et al. (1998).
Most important, human can also become infected with Fasciola spp. and the disease is
referred to as human fasciolosis. It is estimated that 2.4 million people in more than 60
countries are infected and the number of people at risk is more than 180 million throughout
the world Haseeb et al. (2002); Mas-Coma et al. (1999); Ishii et al. (2002). Khalil et al.
(2009) recorded 49.01% prevalence of fasciolosis infestation in buffaloes. He also observed
that optimum infestation was seen from January to September, while minimum during
October to December. Whereas Bhutto et al. (2002) recorded 4% buffalo calves infested with
trematodes.
Introduction

Morphological identification of Fasciola species requires significant parasitological
skills and is not an accurate method of characterization, especially for the ‘intermediate’ form
Kendall et al. (1965); Lin et al. (2007); Le et al. (2008). Hence, different molecular tools have
been developed during the last decade for the accurate identification of Fasciola spp.
Marcilla et al. (2002); Velusamy et al. (2004); Cucher et al. (2006); Magalhaes et al. (2008);
Ai et al. (2010). Conventional techniques like fecal examination used for its diagnosis are not
comprehensive because of Species similarity in distribution in many countries of East and
North Africa, and Southeast and Central Asia, and are similar in egg morphology.
Coprological methods continue to be the most widely used approach for the detection and
quantification of Fasciola and other helminth eggs in laboratory animals, domestic and
sylvatic animals and humans Cringoli et al. (2004, 2010); Bergquist et al. (2009), with a more
recently developed method that is currently undergoing broad-scale validation the FLOTAC
techniques Cringoli et al. (2010) for the detection and quantification of F. hepatica eggs in
feces obtained from experimentally-infected rats before and after drug administration.
FLOTAC has been used successfully in the diagnosis of F. hepatica infections in naturallyinfected
sheep, which underwent treatment with standard Cringoli et al. (2006). However
PCR based diagnosis using specie-specific primers has been proved more accurate and
successful in diagnosis and distinction of Fasciola species Le TH et al. (2012). The molecular
technique such as PCR is used for the recognition of parasite. These molecular techniques are
largely accepted all over the world. These are more exact methods than traditional in
epidemiological studies Heckeroth and Tenter et al. (1999).
Herbal drugs have been used since ancient times to cure diseases and medicinal plants
have been used to treat fasciolosis among these Nigella sativa and Allium sativum have been
used to treat the worm infestation. No report of resistance development to plant anthelmintic
although many have been used in veterinary medicine for many years Ashaal et al. (2010);

Publisher: 2015Dissertation note: Brucellosis mainly infects food animals such as cattle, buffalo, goats and sheep. Brucella abortus is the principal cause of brucellosis in cattle and is shed from the infected animal at or around the time of calving or abortion. The present study was conducted on 450 animals on three different strains/breeds of cattle i.e. Exotic (150), Cross-bred (150) and local cattle (150) from 10 different privately owned livestock farms of varying holdings of district Lahore. An epidemiological questionnaire focusing on herd traits as well as husbandry and sanitary practices that could be associated with the risk of Brucellosis infection was completed. Serum samples were collected and analyzed using Rose Bengal Plate Test (RBPT). The serum samples positive for Brucellosis through RBPT further subjected to Serum Agglutination Test (SAT). To check the effect of Brucellosis on hemogram, blood samples from 18 cattle (n=6 indigenous; n=6 cross-bred; n=6 exotic) positive for Brucellosis and 18 animals (n=6 indigenous; n=6 cross-bred; n=6 exotic) negative for brucellosis were collected and processed for TLC, DLC, RBC, Hb, MCV, MCHC MCH and platelets using automated haematology analysed at UDL, UVAS, Lahore. Similarly, to see the effect of Brucellosis on Serum biochemistry, serum samples from 18 cattle (n=6 indigenous; n=6 cross-bred; n=6 exotic) positive for Brucellosis and 18 animals (n=6 indigenous; n=6 cross-bred; n=6 exotic) negative for brucellosis collected and analysed for glucose, total protein, albumin, Creatinine, Alanine Aminotransferase (ALT), Aspartate Aminotranferase (AST) and Sorbitol Dehydrogenase (SD) using commercially available kits.
Summary

Prevalence Of Hydatidosis In Small Ruminants Slaughtered At District Dera Ghazi Khan Punjab
by Muhammad Qumer Zaman (2007-VA-96) | Dr. Nisar Ahmad | Dr. Muhammad Lateef | Dr. Jawaria Ali khan.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Hydatidosis is important zoonotic and economic disease of livestock and human beings.Hydatid cyst is larval form of genus Echinococcosis Granulosis. Hydatidosis causes considerable economic loss in livestock due to condemnation of organs. Dogs are the primary definitive hosts for this parasite, with livestock acting as intermediate hosts and humans as aberrant intermediate hosts. The outcome of infection in livestock and humans is cyst development in the liver, lungs, or other organ system. The disease is spread when food or water that contains the eggs of the parasite is eaten or by close contact with an infected animal. The eggs are released in the stool of meat-eating animals that are infected by the parasite. For these animals to become infected they must eat the organs of an animal that contains the cysts such as sheep or rodents.The type of disease which occurs in people depends on the type of Echinococcus causing the infection. It is a type of worm infection and is a neglected tropical disease.
To find out the prevalence of Hydatid cyst in small Ruminants, total 300 samples were studied from 300 samples, 150 were of sheep and 150 samples were of goat.Among those samples infected organs of animal like liver ,lung heart were separated in sterile container.then hydatid cyst fluid be obtained by penetrating the needle into cyst wall .A drop of cyst fluid was taken on microscopic Glass slide and cover slip was applied on it and observed under microcope for motility of flame cells to see viable protoscoleces ,live and movable protoscoleces identify as fertile cyst.
Summary
Conclusion
This study Will be helpful to acess the prevalence of zoonotic hydatid cyst disease in the Punjab, Dera Ghazi Khan area and surroundings.And study ultimately help us to control the spread of zoonotic infection and we were be able to guide public to adopt preventive mesures against the disease.

Publisher: 2016Dissertation note: Gastrotomy is suggested in case of gastric dilatation with volvolus, gastric foreign bodies, gastric retention, out flow obstruction, hypertropicgastropathy, gastric neoplasia, and gastroduodenal ulceration. Gastrotomy closure technique after gastric surgery is very crucial to avoid post-operative complication like peritonitis. Different techniques are considered to close gastric incisions like absorbable suturing material, stapler suture and use of adhesive glue. These techniques give different kind of effects on gastrotomy closure.
The present study was carried out on 12 adult mongrel dogs with an average of 15 to 20 kg body weight. They were divided into three groups, each group having 4 animals and designated as group A, B and C. Standard Gastrotomy procedure was performed in group A B and C. After performing surgery, the dogs of group A were sutured by cushing suture, followed by continuous lambert suture by 2/0 synthetic absorbable suture. While in group B dogs, stapler sutures were used to close gastric incision and in dogs of group C, incision site was closed through use of tissue adhesive glue (cyanoacrylate).
Comparison of all suturing and sutureless techniques was carried out through Physical evaluation, food, water intake and defecation, Weight loss / gain, Complete Blood Count, Leakage evaluation by contrast radiography and postmortem findings. It was concluded that suturing technique (using absorbable suture material in two layers) maybe considered much better than other two methods (adhesive glue and stapling) economically, due to use of ease and least post-operative complication. Although glue may be considered as second option due to easy handling, minimum fibrosis, least stenosis and better healing time. Stapling may be the third one

because it experiences difficulty to fire, greater chances of infection due to staples and more prone to leakage and stenosis.
The results of this study will help veterinarian, field workers and pet practioners to use suturing technique as most effective and appropriate technique for gastrotomy closure in terms of better healing, less blood loss and least chances of post operation complications.
