First surveillance and molecular identification of the Cryptosporidium skunk genotype and Cryptosporidium parvum in wild raccoons (Procyon lotor) in Osaka, Japan

Recent research suggests that raccoons ( Procyon lotor ) can transmit several important pathogens affecting humans, including protozoans. In Japan, the number of wild raccoons has increased since they were first introduced more than 50 years ago. Here, we report the first survey of Cryptosporidium i...

Description
Summary:Recent research suggests that raccoons ( Procyon lotor ) can transmit several important pathogens affecting humans, including protozoans. In Japan, the number of wild raccoons has increased since they were first introduced more than 50 years ago. Here, we report the first survey of Cryptosporidium infection using fecal swabs of raccoons captured in Osaka, Japan. Of 116 raccoons examined by PCR targeting of the Cryptosporidium 18S rRNA gene, 7 (6.03%; 2 adults and 5 young animals) were positive, and the isolates were identified as Cryptosporidium skunk genotype (subtype XVIa) and C. parvum based on sequence and phylogenetic analyses. Both species and the genotype are zoonotic; thus, our results suggest that raccoons could transmit Cryptosporidium infections to humans in Japan.
