[Prevalence of Strongyloides spp. infection in household dogs].
A total of 1,505 household dogs were investigated for the prevalence of Strongyloides spp. infection by fecal examination in relation to their fecal conditions, rearing environments, origins, age, sex and breed. Strongyloides spp. infection was demonstrated in 29 of 1,505 (1.93%) dogs. Strongyloides stercoralis was detected in 28 dogs, and Strongyloides planiceps was detected in one dog. The rate of Strongyloides spp. infection was higher in dogs reared indoors, originated from pet shops/breeding kennels and aged 1-6 months. The infected rate was higher in dogs excreting soft feces. No significant sex-related difference was observed in Strongyloides spp. infection. The rate was high in Pomeranians and low in mongrels. The detection of S. stercolaris in dogs reared indoors will involve a serious problem in public health, because the parasite has zoonoitic potential. It suggests that a positive sanitary instruction against a dog's owner and a worker in pet shops/breeding kennels seems necessary for prevention of transmission from dogs to humans. Furthermore, the reliable treatment for dogs infected with S. stercoralis seems to be important.
