Prevalence of Haemoprotozoan Disease in Cattle in Rainy Season

Abstract

Prevalence of haemoprotozoan disease in cattle during rainy season was studied by examining 803 blood smears of suspected cases, received on the reference of field veterinarians from July 2016 to November 2016. Mostly the cases were with general clinical symptoms of pyrexia, anorexia, anaemia, pale conjunctiva membrane, corneal opacity, swollen lymph node, haemoglobinurea, nasal discharge and coughing, circling movement, grinding of teeth, reduced milk yield and abortion. Out of which, 598(74.47%) cases were found positive for haemoprotozoan disease by using Giemsa staining technique. Among different haemoprotozoan diseases, the highest prevalence of theileriosis (42.59%) was recorded followed by anaplasmosis (7.97%), trypanosomosis (1.62%) and babesiosis (1%). However, 21.29% of the cases were found positive for mixed infection. Most of the cases of mixed infection were observed concomitant infection of theileriosis and anaplasmosis. Such type of cases was found more severe than the cases with single infection.
