Abstract:
The present study was undertaken to know the prevalence of Bovine Theileriosis in South Bihar, during the period of June’2019 to May’2021 with the randomized sampling of biological sample with three districts of south Bihar by collecting blood samples from 500 tick infested animals. Thin blood smears were prepared, air dried, fixed with methanol and stained with Giemsa stain. The microscopic observation of stained blood smears was done to observe the presence of intraerythrocytic piroplasms, indicator of theileria. Prevalence of Theileriosis in South Bihar was recorded to be 33.20% and among 3 studied district, prevalence of Theileriosis was highest in Nawada (35.92%) followed by Patna (33.75%) and the least in Sheikhpura (27.03%). The highest number of clinical Theileriosis were recorded (47.59%) in rainy followed by summer (31.33%) and least in winter (21.08%) season. Age wise prevalence was found to be highest in above 3 years age group (40.98%) followed by 1-3 years age group (27.70%) and least in below one year age group (18.60%). Higher prevalence was occurred in females (35.19%) than males (20.59%) and more in lactating ((42.35%) than non-lactating (23.42%) cattle. Under breed wise, the highest prevalence (38.20%) occurred in HF cross followed by Jersey cross (30.46%) and least in non-descript breed (18.64%) of cattle.
