Abstract

Prevalence of microfilariae, Dirofilaria immitis, Dirofilaria repens, Acanthocheilonema dracunculoides from 506 German Shepherd dogs reared in Korea was investigated by modified Knott's test to detect circulating microfilaria and by acid-phosphatase staining for differentiation of each microfilaria species. In the modified Knott's test, 74 of 506 dogs (14.6%) were microfilaria positive, and the prevelance of each species of microfilaria was 90.5% (67 of 74 samples) for D. immitis, 5.4% (4 of 74 samples) for duplicate infection with D. immitis and D. repens and 4.1% (3 of 74 samples) for mixed infection with D. immitis, D. repens and A. dracunculoides. It was considered that the paying attention to the existence not only D. immitis but also other microfilariae were needed in canine filariasis.

Key Words: microfilaria, modified Knott's test, acid phosphatase staining
