Abstract
- Enterocytozoon bieneusi is an obligate intracellular microsporidian parasite with a worldwide distribution. As a zoonotic pathogen, E. bieneusi can infect a wide range of wildlife hosts through the fecal-oral route. Although the feces of flying squirrels (Trogopterus xanthipes) are considered a traditional Chinese medicine (as "faeces trogopterori"), no literature is available on E. bieneusi infection in flying squirrels to date. In this study, a total of 340 fresh flying squirrel fecal specimens from two captive populations were collected in Pingdingshan city, China, to detect the prevalence of E. bieneusi and assess their zoonotic potential. By nested PCR amplification of the ITS gene, six specimens tested positive, with positive samples from each farm, with an overall low infection rate of 1.8%. The ITS sequences revealed three genotypes, including known genotype D and two novel genotypes, HNFS01 and HNFS02. Genotype HNFS01 was the most prevalent (4/6, 66.7%). Phylogenetic analysis showed that all genotypes clustered into zoonotic Group 1, with the novel genotypes clustering into different subgroups. To our knowledge, this is the first report of E. bieneusi infection in flying squirrels, suggesting that flying squirrels could act as a potential reservoir and zoonotic threat for E. bieneusi transmission to humans in China.<br /> (© X.
