To survey the prevalence of coccidium infection in cats and dogs in the Tama area, Tokyo, fecal samples were collected from 834 kittens during 1975 to 1979 and from 224 puppies during 1978 to 1982, and examined by the sugar flotation method. Isospora felis oocysts were detected in 30 kittens (3.6%), I. rivolta in 5 (0.6%), Besnoitia wallacei in 6 (0.7%) and Toxoplasma gondii in 5 (0.6%). No oocyst of other coccidian species was observed in feces of these cats. This result indicated that 4 species of feline coccidia existed constantly in the Tama area, Tokyo. I. canis oocysts were detected in 4 puppies (1.8%), and I. ohioensis in 28 (12.5%). Two puppies were infected with both I. canis and I. ohioensis. No oocyst of other species was detected in dogs.
