Abstract

An epidemiological study was conducted to investigate the epidemiology of humpsore (stephanofilariasis) infection on cattle of different age and sex by collecting information from samples conveniently from different areas of Mymensingh district in Bangladesh. Clinical history and direct examination is done to detect the infection. Out of 503 samples total 43.14% cattle were found stephanofilariasis positive. The prevalence of stephanofilariasis was higher (27.24%) in cattle between 5-10 years old cattle than of less than 5 years (10.93%) and more than 10 years (4.97%) old cattle. Females have shown more positive (36.98%) result than male (male entire= 3.18%, male castrated= 2.98%) that was 6.16% (Odds ratio= 1; P value= 0.987, ?²= 0.003). Local breed shown 36.98% positive to stephanofilariasis followed in descending order by 2.98% in Red Sindhi, 0.99% in Sahiwal, 0.80% in Jersey cross, 0.40% in Holstein cross, Haryana and Red Chittagong breeds and 0.20% in Pabna breed.
