• Enterocytozoon bieneusi is a potentially important zoonotic pathogen. However, there is no information on E. bieneusi infection of captive long-tailed macaques (Macaca fascicularis) in Hainan Province, China. Here 193 fecal specimens of M. fascicularis were collected from a breeding base in Hainan Province, China, housing non-human primates for experimental use. E. bieneusi was identified and genotyped by nested PCR analysis of the internal transcribed spacer (ITS) region of the rRNA gene. A total of 59 (30.6%) specimens were PCR-positive for E. bieneusi and 16 ITS genotypes were identified including nine known genotypes: Type IV (n = 19), D (n = 11), CM1 (n = 8), PigEBITS7 (n = 4), Pongo2 (n = 4), Peru8 (n = 3), Peru11 (n = 1), WL21 (n = 1) and CM2 (n = 1) and seven novel genotypes HNM-I to HNM-VII (one each). Importantly, genotypes D, Type IV, Peru8, PigEBITS7, and Peru11, which were the predominant (38/59, 64.4%) genotypes identified among captive M. fascicularis in this study, are also well-known human-pathogenic genotypes. All the genotypes of E. bieneusi identified here, including the seven novel ones, belonged to zoonotic Group 1. This is the first report of the identification of E. bieneusi in M. fascicularis in Hainan Province, China. The finding that the numerous known human-pathogenic types and seven novel genotypes of E. bieneusi all belong to zoonotic Group 1 indicates the possibility of transmission of this important pathogenic parasite between M. fascicularis and humans.
