摘要： Enterocytozoon bieneusi is a common microsporidian species, which can infect humans and various species of animals. However, little is known about E. bieneusi prevalence and genotypes in farmed raccoon dogs (Nyctereutes procyonoides) in Shandong Province, China. In this study, a total of 356 fecal samples were collected from farmed raccoon dogs in Weihai, Weifang, and Yantai cities in Shandong Province, China. A total of 23 (6.5%) samples were E. bieneusi-positive by nested PCR amplification of the internal transcribed spacer (ITS) region of ribosomal DNA. Statistical analysis showed that E. bieneusi prevalence in male raccoon dogs was higher than that in female raccoon dogs, and the highest E. bieneusi prevalence was detected in adult raccoon dogs. Sequence analysis revealed four known E. bieneusi genotypes (D, type IV, CHG1, and Peru8), and type IV (11/23) was the predominant genotype. The genotypes type IV, Peru8, and CHG1 were reported in raccoon dogs for the first time in China. Phylogenetic analysis showed that three human-pathogenic genotypes (D, type IV, and Peru8) were clustered into group 1, and the CHG1 belonged to group 2. These findings expand the current understanding of E. bieneusi prevalence and genotype distribution in raccoon dogs in China. Our study also shows that raccoon dogs are hosts for E. bieneusi belonging to several genotypes, including zoonotic ones, highlighting the possibility of transmission of this pathogen between raccoon dogs and humans.
