Publisher: 2012Dissertation note: A cross sectional study was conducted during February 2012 to April 2012, in Chagai district, Balochistan. Information about education and economic status of the farmers, managemental practices, vaccination, outbreak history, veterinary services and transboundry animal movement was collected from 323 (282/323 farmers and 41/323 livestock traders) on a structured questionnaire. The status of foot and mouth disease (FMD) is not known in Chagai, following research has been planned to see the potential association between farming practices and FMD.
Factors which were significantly associated with the occurrence of foot and mouth disease in district Chagai were education level of Farmers (illiterate 60%, literate 40%) and livestock traders (illiterate 42%, literate 58%), socioeconomic status of the farmers <20000 rupees (63%) and >20000 rupees (37%) and livestock traders <20000 rupees (12%) and >20000 rupees (88%), type of animals in the herd of farmers (cattle, 2%, sheep 4.2%, goat 19%, cattle-sheep-goat 9% and sheep-goat 67%) and livestock traders (cattle 17%, goat 3%, cattle-sheep-goat 68% and sheep-goat 12%), housing system used by farmers (open 93%, closed 7) and livestock traders (open 12%, closed 78%), feeding methods in case of farmers (grazing 93%, stall feeding 7%) vaccination against FMD farmers (yes 3%, no 97%) and livestock traders (yes 39%, no 61%), veterinary services available to farmers (yes 17%, no 87%) and livestock traders (yes 48%, no 52%) , nomadic movement of farmers (yes 62%, no 38%), export of live animals (yes 73%, no 27%) and import (yes 10%, no 90%). Other managmental practices like quarantine (no, 100%), isolation of sick animals from the herd (no, 100%), feeding of young animals milk of the sick mothers (yes, 100%) and proper disposal of the dead animals (no, 100%) were factors which were not analyzed due to zero cell values.
It is concluded that illiteracy, poor economic status of farmers, type of animals (sheep and goat), open housing system, mixed grazing in the range land, low vaccine coverage, poor veterinary services and free movement of animals are strongly associated with the occurrence of foot and mouth disease in Chagai district. Transboudry animal movement of livestock to and from Afghanistan and Iran can aggravate the situation. Regular vaccination of livestock and awareness of farmers can help to improve the animal health status in Chagai.

Seroprevalence Of Brucellosis In Pregnant And Aborted Women Of Rural And Urban Areas In Three Selected Districts Of Punjab Pakistan
by Shakeela Anjum (2006-VA-172) | Dr. Iahtasham khan | Prof. Dr. Abdul shakoor | Prof. Dr. Muhammad Younus.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Brucellosis is an important zoonotic disease of animals and human. According to OIE
(Office International des Epizooties), it is the second most important zoonotic disease in the
world after rabies Brucellosis is more common in countries with Poorly standardized animal
and public health programme. Human Brucellosis caused by B. abortus, B. abortus are small,
non-motile, aerobic, facultative intracellular, Gram-negative cocobacilli.
The symptoms of human brucellosis are undulant fever, headache, weakness, body
pain, and sometimes endocarditis, orchitis, or arthritis may develop. Prolonged use of
combination of antibiotics and human vaccine is main control measure strategies for human
brucellosis. This disease is under investigated and hence people are ignorant of this insidious
problem. Serological surveillance is a good and cheap tool to diagnose this problem. There is
also need to know that which diagnostic antigen (Pakistani or French) is more sensitive and
specific from disease eradication and control point of view. Unfortunately annual incidence
of brucellosis in whole Pakistan is unknown but they are expected above 2 per 100,000
people. The hypothesis of present study was that brucellosis is considered to be endemic in
Pakistan but there is no data available about seroprevalence of brucellosis in pregnant,
aborted, rural and urban women with different risk factors in Pakistan.
In present study sero-screening of total 199 serum samples of pregnant and women
presenting with abortions from district Jhang, district Chinoit and district Faisalabad. Test
was performed on 199 samples which showed 40 (20%) positives by RBPT (Pakistan) and 42
(21%) positives by RBPT (France) (Table 4.4). While the indirect modified ELISA showing
5 (2.5%) positive samples. All sera tested positives (5) with modified i-ELIA were also tested
positives with another specific and highly expensive ELISA (Verion Serion) at OIE reference

Laboratory for brucellosis, Germany. Prevalence data was analyzed by chi square test
using SPSS version 20 Software (Apache License, USA) to find out correlation between risk
factors and brucellosis prevalence.
Risk factors such as consumption of raw milk, contact with animals, and symptoms
were significant. In our opinion, indirect modified ELISA is more sensitive than RBPT
(Pakistan) and RBPT (French). RBPT, (Pakistan) can be used for primary screening of
brucellosis cases because of cross reactivity present in RBPT antigen and confirmation must
be made with a more specific and sensitive serological test, such as B. abortus-specific
indirect modified ELISA. The results of present study showed that RBPT, Pakistan antigen
showed almost same sensitivity and specificity as that of RBPT (Pourquier, France) antigen.
Indirect modified ELISA is more specific as compared to RBPT (Pakistan) and RBPT
(French). It is highly suggestive to combine serodiagnostics test with molecular detection
including PCR and Real time PCR to increase the detection rate of brucellosis. Human
ELISA kit is extremely expensive that cannot be afforded in developing countries like
Pakistan to screen the human. PCR technique is highly reliable and less time consuming. It is
highly suggestive to conduct the study on human brucellosis on other districts of south
Punjab as it is believed that brucellosis is endemic due to lack of awareness and vaccination
in these areas. Availability: Items available for loan: UVAS Library [Call number: 2359-T] (1).

Seroprevalence Of Brucellosis In Ruminants At Sale And Purchase Markets And Abattoirs In Three Selected Districts Of Punjab, Pakistan
by Muhammad Tahir (2008-VA-301) | Dr. Iahtasham Khan | Prof. Dr. Muhammad Younus | Dr. Syed Ehtisham-ul-Haque.
Material type: ; Literary form:
not fiction
Publisher: 2016Dissertation note: This is a representative study from Pakistan accompanied in three districts of
Punjab i.e. Jhang, Layyah and Toba Tek Singh which are rich in livestock population.
There is a lot of research work on livestock farms but the sale and purchase markets and
abattoirs are neglected. Pakistan is an agricultural country and livestock contribute a major
share to agriculture in Pakistan GDP and its economy. Sheep, goats, cattle and buffaloes
contribute in the economy of Pakistani people by milk and meat production on majority
basis. Livestock contribution to the agriculture value added is 56.3%, while it contributes
11.9% to the national GDP during 2014-15. More than 8.0 million rural families of the
country are involved in raising livestock. But productivity of livestock is questioned by a
lot of factors. Infectious zoonotic diseases are among these.
Brucellosis is one of the major and unreported problem amongst livestock markets
and abattoirs of our country. It results in losses to the economics of the farmers or owners
in terms of poor health, abortions, long calving interval, production of weak offsprings and
deprived quality of milk and meat. This disease is under investigated and hence people are
unaware of this deceptive problem. Serological surveillance is a good and cheaper tool to
diagnose this problem. Determination of the seroprevalence is important to know the load
of disease and pockets of infections in the area of Punjab, Pakistan. There is also a need to
know which diagnostic antigen is more sensitive and specific from disease eradication and
control point of view.
A total of 300 animals serum samples were collected from three districts of the
Punjab province and tested by conventional screening test i.e. Rose Bengal Plate
Agglutination Test (RBPT) by using two antigens of different countries origin i.e. VRI
(Lahore, Pakistan), IDEXX (Pourquier, France) and ID.vet, France and then tested with
indirect Enzyme-linked Immunosorbent Assay (iELISA). The data thus obtained regarding
seroprevalence was analyzed using Chi-square SPSS version -19 (Nahar et al. 2009).
Of the total 300 animals (77 male and 223 female), 1.3% male and 35.66% female
were seropositive for anti-Brucella antibodies. Different risk factors were also included in
study like sex, area, age, gender, abortion, reproductive problems and also history of orchitis
in male. All of these risk factors were statistically analyzed to reveal the truth about ruminants
brucellosis. Among the various risk factors studied, the risk factors including history of
abortion (16.44%), orchitis (1.3%), retained placenta (26.47%), species cattle (35.55%) and in
Toba Tek Singh (47.36%) were statistically significant which could be potential source of
threat for humans and other animals. The testing was performed using conventional methods
as well as using iELISA. It is concluded that iELISA is more sensitive and specific than
conventional screening tests but molecular diagnosis is highly recommended for future
studies. The current study will help to minimize and eradicate the low prevalence of ruminants
brucellosis by creating awareness between the farmers and through vaccination and herd
immunization. By implementing the policy of testing and culling of positive reactors will be
pivotal to achieve the objectives.
For confirmatory diagnosis all the sera were further tested with iELISA. For this
purpose an exclusive commercially available iELISA Kit (ID.vet, France) was used which
would be able to differentiate anti-Brucella antibodies of B. abortus and B. melitensis and this
iELISA kit would be able to be used for multispecies including cattle, buffaloes, sheep and
goats. Availability: Items available for loan: UVAS Library [Call number: 2556-T] (1).

Application Of Euroscore To Predict Risk Of Mortality After Coronary Artery Bypass Grafting In Pakistani Population
by Ali Naeem (2014-VA-780) | Dr. Muhammad Hassan Mushtaq | Dr. Ammar Hameed Khan | Dr. Mamoona Chaudhry | Dr. Muhammad Nasir.
Material type: ; Literary form:

Publisher: 2016Dissertation note: Coronary artery bypass surgery has become the standard of care for advanced coronary artery disease. It is one of the most audited and closely monitored operations in the history of surgery. Morbidity and mortality associated with this operation is also very closely monitored by surgeons, hospitals, professional bodies and governments at large. Based on the preoperative clinical information available about patients preparing to undergo coronary artery bypass surgery various predictive models for assessment of mortality risk have been developed over the last two decades in various regions across the world. Euro SCORE is one such predictive model which can accurately predict the risk of mortality for large groups of patients for the population in which it was developed. A large number of Pakistanis and nationals from South East Asian countries reside in different European countries and form part of the population on which this score has been developed and validated. We intend to find out the predictive accuracy of this model in our patients living in Pakistan.
Euro SCORE accurately predicts operative mortality in patients from Pakistani population.
This study will be conducted at the Department of Cardiac Surgery Shalamar Hospital Lahore. One hundred consecutive patients admitted to hospital for coronary artery bypass surgery will be enrolled in study. A total of 18 variables as included in EuroSCORE (Appendix 1) will be collected and entered into database. The expected mortality risk will be calculated by the EuroSCORE Calculator software (http://www.euroscore.org/). Actual or observed mortality and morbidity will also be recorded.
Statistical analysis will be performed using SPSS version16. Continuous numerical data will be presented as mean ± Standard deviation, the Student t test will be used to compare means of normally distributed data. The qualitative data will be analyzed using chi square test. The relationship of the observed and the expected rates of mortality will be assessed using ROC curves for the accuracy of prediction of the Euro-SCORE.
This study will indicate how accurately Euro SCORE can predict the risk of mortality after coronary artery bypass grafting in our population and more over it may indicate other patient related variables that can contribute to operative mortality other than Euro SCORE.
