Abstract | This study aimed to conduct a cross-sectional study to investigate the prevalence of haemoprotozoan diseases in Sylhet district of Bangladesh. A one year (January to December 2018) study on hemoprotozoan diseases was conducted in crossbred and indigenous cattle. Blood samples were collected randomly from 81 crossbred and from 19 indigenous cattle from four representative areas in three seasons. Blood samples were examined by Giemsa’s stained thin blood smear method. The effect of breed, sex, age and season was observed in cattle during this study. The overall prevalence of haemoprotozoan diseases in Sylhet district was 52%. Three (3) types of haemoprotozoan diseases have been identified (Anaplasmosis, Babesiosis, Mixed) among them prevalence of Anaplasmosis was 28%, babesiosis was 08% and mixed infection was 15%. The prevalence of haemoprotozoan diseases was not significant (P>0.05) in relation to breed but the highest prevalence found in crossbreed cattle was Anaplasmosis (29.63%). Sex-wise prevalence was also not significant (P<0.05) in each of the diseases and here, the highest prevalence was found in male (31.48%) in case of Anaplasmosis. In relation to age, only mixed infected cattle were differ significantly (P<0.05) where the highest prevalence was observed (30.43%) in case of Anaplasmosis. Hemoprotozoan diseases were predominant in summer (36.11%) season followed by rainy (29.41%) and winter (16.67%) season. In case of mixed infection, adult cattle had significantly higher prevalence which was statistically significant (P<0.05). Study results revealed that burden of haemoprotozoan diseases are apparently high in Sylhet district regardless of the age, sex, breed and season. The data generated through this study will help to take adoptive control measures against haemoprotozoan diseases in Bangladesh.
