Abstract

A survey on the prevalence of internal parasites in the laboratory rats in the Chonnam and Kyunggi areas was carried out. A total of 208 rats was selected for necropsy and the parasites were collected from the organs and the fecal samples. The infection rate of the internal parasites was high as 63.9% and eight species of parasites were identified. Among the species identified A tetraptera(21.6%) and H diminuta(20.7%) appeared with relatively higher infection rates than any other species identified. A significant difference in numbers of parasites was recognized between the regions as 8 species in Chonnam and 4 species in Kyunggi. The laboratory rats reared in stainless steel cage showed the higher infection rate than those in polycarbonate cage, with some exception in H spumosa and H nana. In this survey T crassicauda was firstly in the laboratory rats in Korea.
