Abstract

Fecal samples were collected from 325 adult cattle and 108 pigs in a slaughterhouse in Hokkaido, the northern island of Japan. Five adult cattle were found to be positive for oocysts of Cryptopsoridium (1.5%). The oocysts were morphologically similar to those of Cryptosporidium andersoni. The partial sequence of the 18S rRNA gene of the isolate was 100% identical with that of the C. andersoni Kawatabi strain. SCID mice were infected after oral administration. Based on the morphology of the oocysts, the sequence of the 18S rRNA gene and the infectivity to SCID mice, the isolate was concluded to be of the same type as the C. andersoni Kawatabi strain that has been isolated in Honshu, the main island of Japan.
