Conventional And Molecular Characterization Of Theileria Species Prevalent In Cattle

by Fafiz Muhammad Nadeem (2003-VA-77) | Dr. Nisar Ahmad | Prof. Dr. Azhar Maqbool | Dr. Muhammad Ijaz.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Theileriosis is the destructive disease caused by the protozoan in cattle. It is major cause of huge losses in production of cattle. It is a wide spread protozoan syndrome of cattle playing foremost role in production losses. Early and exact diagnosis of theileriosis can be helpful in reducing production losses. Early and exact diagnosis of theileriosis can be helpful in the control of disease.( Hypothesis ) Incidence of different Theileria species was recorded. Blood samples was collected in sterilized vacutainers. The samples were examined by preparing fresh blood smears followed by Giemsa staining and observing under microscope. Identification on preliminary basis was done by morphological characters of Theileria. In order to find the harmful effect of the theileriosis, blood hematology and biochemistry values were also be determined in both healthy and infected cattle. The samples from theileriosis positive animals were used for nucleic acid extraction. The extracted nucleic acid was amplified using Species specific primers.Agarose gel electrophoresis was used to visualize the amplified DNA. Amplicons of nucleic acid was treated with different restriction enzymes and pattern was visualized to find differences among different species of Theileria. Suitable statistical tool was used to analyze the data collected. Chi was applied on data by using statistical software SPSS version 20.0. This research will help to confirm for the conventional and molecular diagnosis of theileriosis in dairy animals. Also genetic variation in Theileria species will be determined.

Prevalence Of Intestinal Parasites From Fingernails Of Primary School Going Children Of District Lahore

by Javeria (2012-VA-16) | Dr. Nisar Ahmed | Prof. Dr. Kamran Ashraf | Dr. Muhammad Ijaz.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Intestinal parasitic infections are extensively spread globally and most affected population is children. In primary schools environments children are confirmed as a most susceptible for acquiring Intestinal parasites(IP) through nails. Intestinal parasites were more prevalent in fingernails of children of primary schools in District Lahore. A total of 300 nail samples were collected from the fingernails of the school children of different age and sex. The nails were swabbed into a clean sterile container containing normal saline. Finger nail clippings were collected from both hands of each subject using sterile nail clippers and were placed in labeled containers containing normal saline. Samples were examined by direct microscopy using Lugol’s iodine and Eosin preparations. Sediments from the nail clippings were examined after digestion with 10% Potassium hydroxide and centrifugation at 2500rpm for 5minutes.The parasites were isolated from the fingernails of the primary school children of both sexes and prevalence was recorded. The collected data was analyzed using SPSS version 20. The prevalence of parasites was presented as descriptive statistics, while the relationship between several variables (age, gender,educational level) and presence of parasites was determined by the chi-square test. The level of significance used was P<0.05. This study will help to create awareness among society especially school children about parasites and parasitic infections. It will also help to improve health level of school children, education and environment of schools and will develop the habit of keeping hygiene and handwashing practice in children as a result of which a healthy study competition will be developed among school children.

Control Of Nematode Infections In Bovines In Different Parity At Calving And Its Effect On Milk Production

by Muhammad Saqib Ali (2008-VA-188) | Prof. Dr. Khalid Saeed | Dr. M. Imran Rashid | Dr. Muhammad Ijaz.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Gastrointestinal nematodes are responsible for wide range of health problems, economic losses in bovines and are characterized by reduced milk production, decreased working efficiency and even death. This study was done to evaluate the effect of different anthelmintics on nematode control in different parity cattle at calving and their effect on milk yield. In this study, we screened cattle of 1st and 2nd parity for nematodes. Animals were randomly selected in each group. In first parity animals, we found 23 positive cattle which were divided into 3 different groups while in second parity animals, we found 20 positive cattle which were divided into 3 groups. We used Albendazole (Velbazine) @ 10mg/kg body weight and levamisole (Nilverm) @ 7.5mg/kg bodyweight for treatment. In this study both drugs were found effective in controlling nematodes infections in cattle. Percentage reduction of epg by albendazole was 48.20%, 85.34%, 93.90% and 51.54%, 81.43%, 91.74% on day 7, 14 and 21 in 1st and 2nd parity animals respectively. Percentage reduction of epg by levamisole was 44.45%, 76.92%, 88.03% and 46.60%, 73.78%, 85.43% on day 7, 14 and 21 in 1st and 2nd parity animals respectively. The increase in milk production in current study was 0.39 liter per day and 0.92 liter per day in 1st and 2nd parity cattle respectively. Albendazole increased the milk fat by 0.07 %, while levamisole decreased 0.02 % in 1st parity cattle. In 2nd parity cattle, there was sufficient increase of 0.1% of milk fat by albendazole while levamisole has decreased 0.05 %. We conclude from our studies that anthelmintic treatment of recently calved cattle have significant effect on milk production due to the nematode control. Milk production increased significantly in 2nd parity friesian crossed cattle following anthelmintic treatment as compared to Summary 70 1st parity animals. Levamisole has negative effect on fat concentration in friesian crossed cattle while albendazole treated cattle has positive effect. Albendazole has been found more efficient in reducing EPG of helminths in both parity animals as compared to levamisole treated animals. It is recommended that cattle should be checked for GIT parasites by faecal examination on regular basis so that cattle should be dewormed when needed.
