Genetics, Evolution, and Phylogeny - Short Communication
Enterocytozoon bieneusi is an opportunistic enteric pathogen which can infect a wide range of animal species and humans. It is the most diagnosed species of Microsporidia in humans and has an impact on public health. Many infected animals including foxes may be a potential source for transmitting E. bieneusi to humans. However, limited information is available on the E. bieneusi prevalence and genotypes in farmed foxes in China. Therefore, in the present study, 344 fresh fecal samples were collected from farmed foxes (Vulpes vulpes and Vulpes lagopus) in Shandong Province, and the prevalence and genotypes of E. bieneusi were examined based on sequence analysis of the ribosomal internal transcribed spacer (ITS) region. The overall E. bieneusi prevalence was 9% (31/344); of them, 6.5% (9/138) in farmed silver foxes (V. vulpes) and 10.7% (22/206) in farmed arctic foxes (V. lagopus). Moreover, four known (Hum-q1, NCF2, HND-1, and Type IV) and two novel E. bieneusi genotypes (SDF1 and SDF2) were identified in farmed foxes in the present study. All of the E. bieneusi genotypes belonged to the zoonotic group based on phylogenetic analysis. In addition, 2, 4, 0, and 11 samples were successfully amplified at MS1, MS3, MS4, and MS7 loci, respectively. The present study reveals E. bieneusi prevalence and genotype distribution in farmed foxes in Shandong Province and enlarged the host and geographic information of E. bieneusi in China.
