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.
