Abstract:
An epidemiological investigation was conducted to ascertain the prevalence of
hemoprotozoan diseases of cattle in Pabna district of Bangladesh, during the period of
January 2021 to December 2021.During study period a total of 60 cattle were
examined from three upazilas (Bera, Santhia and Faridpur) of Pabna district. The
investigation was carried out in three visits on three seasons (summer, rainy and
winter). On Geimsa stained blood smear examination, 14 were found to be infected
with hemoprotoza diseases. Overall prevalence of Anaplasma marginale, Anaplasma
centrale, combined infection of A. marginale and A. centrale and Babesia spp.

of age, sex, breed and seasons were observed in cattle during this study. The highest
prevalence of Anaplasma spp. and Babesia spp. (25% and 10% respectively) was
reported in the older cattle (> 3 years of age) and the prevalence of Anaplasma spp.
and Babesia spp. was higher in female (20% and 10% respectively) than male
(13.33% and 3.33% respectively). All crossbred cattle showed higher prevalence of
Anaplasma spp. and Babesia spp. (23.33% and 10% respectively) than local cattle
(10% and 3.33% respectively). The prevalence of of Anaplasma spp. and Babesia spp.
was noticed as the highest in the rainy season (25% and 10% respectively) in relation
to summer (15% and 5% respectively) and winter (10% and 5% respectively) season.
