abstract
An epidemiological study was conducted to determine prevalence of canine microfilariosis in and around Shivamogga, Karnataka for a period of one year from March-2018 to February-2019. A total of 101 blood samples were collected from dogs suspected for microfilariosis and were screened for microfilaria by modified Knott's method. Out of 101 samples screened, 4 samples were found positive for microfilaria with prevalence of 3.9 per cent. The species of microfilaria was identified as D. repens based on the morphology and micrometry. Age wise prevalence was found highest in 1-3 years old dogs. The infection was seen only in males and no female dogs found positive for microfilariae. The breed wise prevalence was found highest in Boxer breeds. During the present study, the highest prevalence was observed during winter season from January to February months. The infection was found more in dogs kept outdoor as well as near farm area compared house hold dogs.
