Host-adaptation of the rare Enterocytozoon bieneusi genotype CHN4 in Myocastor coypus (Rodentia: Echimyidae) in China.

ABSTRACT:

Background

Enterocytozoon bieneusi is a zoonotic gastrointestinal pathogen and can infect both humans and animals. The coypu (Myocastor coypus) is a semi-aquatic rodent, in which few E. bieneusi infections have been reported and the distribution of genotypes and zoonotic potential remains unknown.

Methods

A total of 308 fresh fecal samples were collected from seven coypu farms in China to determine the infection rate and the distribution of genotypes of E. bieneusi from coypus using nested-PCR amplification of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene.

Results

Enterocytozoon bieneusi was detected with an infection rate of 41.2% (n = 127). Four genotypes were identified, including three known genotypes (CHN4 (n = 111), EbpC (n = 8) a
