Abstract:
Enterocytozoon bieneusi, an important microsporidian fungus, causes chronic diarrhea in humans and animals worldwide. Out of the 502 fecal samples from wild boars, 13 were positive for the E. bieneusi internal transcribed spacer region, with a prevalence of 2.6%. Six E. bieneusi genotypes, D, EbpC, and four novel KWB1-KWB4, were identified with zoonotic potential. Genotypes D (subgroup 1a) and EbpC (subgroup 1d) were first reported in Korean swine and Korea, respectively; KWB1-KWB4 (subgroup 1e) were most prevalent in this study. Because zoonotic genotypes have been identified, E. bieneusi transmission through wild boars must be closely monitored for proper prevention and treatment, despite their low prevalence.
Lay Summary:
Enterocytozoon bieneusi is an important microsporidian fungus. Its sequences from wild boars were identified with zoonotic potential. Genotypes D and EbpC were first reported in Korean swine and Korea, respectively. E. bieneusi should be closely monitored to properly prevent and treat animals.
