Characteristics of a Novel Type of Bovine Cryptosporidium andersoni

ABSTRACT We isolated oocysts that resemble Cryptosporidium andersoni from cattle grazing on a farm in Japan. The partial sequences of genes from the isolate were coincident with published sequences of genes of C. andersoni. Since the isolate was able to infect SCID mice, the isolate appears to be a novel type of C. andersoni.
