Abstract

The case-study was carried out to identify some epidemiological characteristics of Toxocariasis at some communes and wards of Thai Nguyen city. A total of 337 dog feces samples were collected to determine the rate of infection and infectious intensity of dog roundworm using the Fulleborn method. The results of the study showed that the rate of ringworm infection in dogs raised in some communes and wards in Thai Nguyen province reached an average of 35% and the intensity of roundworm infection was mild with a rate of 51.69%. Dogs under 2 months of age have the highest rate of ringworm infection, while domestic dogs at 12 months of age have the lowest rate. Dogs raised in March, April and September had the highest rates of roundworm infection compared to other months of the year. Domestic dogs infected with roundgworm are higher than exotic ones, and female dogs have a higher rate of roundworm infection than male ones.
