Prevalence of Haemoprotozoan Diseases in Black Bengal Goats of Sylhet Region of Bangladesh

The study was conducted to ascertain the prevalence of haemoprotozoan diseases in Black Bengal goat at Sylhet District of Bangladesh during the period from January to December 2018. In this study, determination of haemoprotozoan disease in relation to age, sex and season dynamics were studied. A total of 100 goats were examined, among which 25 (25%) was found to be infected with different haemoprotozoan diseases where Babesiosis was (05%), Anaplasmosis was (12%) and mixed infection was (08%). In this study, determination of haemoprotozoan disease in relation to age, sex and season dynamics were studied. Male(15.22%)animals were more susceptible to Anaplasmosis infections than female (9.26%) where Babesiosis were higher in female (5.56%) than male (4.35%).In case of mixed infection male (8.70%) were more susceptible than female (7.41%).In age group, higher prevalence was found (8.11%) in >2 years of age than (4.17%) in 1-2 years in Babesiosis. Slightly higher prevalence was found (13.33%) in 2 years in Anaplasmosis. Higher prevalence was found (12.50%) in 1-2 years of age where (5.41%) in >2 years in case of mixed infection. In Babesiosis highest prevalence was observed in rainy season (7.50%) followed by winter (3.45%) and summer (3.23%). Comparatively higher prevalence was observed in rainy season (15.00%) followed by summer (12.90%) and winter (6.90%) in Anaplasmosis. In case of mixed infection higher prevalence was observed in rainy (12.50%) than summer (9.68%).In this study it was observed that there was no statistically significant relationship of haemoprotozoan disease in relation to age, sex, and seasonal variation.
