Abstract
Background: Poultry sector is a vibrant segment of Pakistan economy and is a viable source
of animal origin protein source. The growth of this sector is badly affected by different
devastating problem’s in-term of mortality and morbidity. Hazara region is so called Georgia
of Pakistan for poultry Production. Coccidiosis is an economically devastating problem in the
area and throughout the year its cases have been reported.
Methods: The present study was conducted to know the round the year and seasonal
prevalence of disease. During July 2012 to June 2013, a total of 1440 (n=1140) postmortem
cases were carried out for disease diagnosis. Cases suspected for coccidiosis were confirmed
by grass pathological lesions manifestation on the intestine and ceaca. Brief history including
age, flock size was taken. For morphological examination, the oocytes were sieved and
centrifuged at 3000 rpm with sugar solution.
Results: A total no of (n=1440) cases brought to outdoor patient services of Veterinary
Research & Disease Investigation Centre, Abbott bad for disease diagnosis and treatment. Out
of the total cases n=546 were found positive showing the overall prevalence of 37.91%.During
hot and humid climatic conditions of monsoon season its prevalence was significantly high,
during the month of August and September the observed infection percentage as 60.16% and
62.29 % respectively while low infection rate has been observed during the month of April
which was 20.17%. Predominance of eimeriosis was high in young birds (3-4 weeks) and adult
birds and less than 3 week of age birds was 74.90%, 17.94% and 7.14% respectively.
Conclusion: In the present study the higher prevalence of infection during the rainy season of
monsoon observed indicating that warmth temperature and humid condition favors the oocytes
sporulation and subsequent transmission.
