　　Enterocytozoon bieneusi is a zoonotic pathogen of the phylum Microspora that infects humans as well as a variety of animal species worldwide.While molecular epidemiologic studies have characterized this parasite in various hosts,isolates from many susceptible hosts have not yet been examined.This experiment was conducted to study Enterocytozoon bieneusi genotypes in Pere Davids deer(Elaphurus davidianus)in Henan,China.In this study,E.bieneusi was isolated from 47 Pere Davids deer(Elaphurus davidianus)in Henan,China and characterized via PCR analysis of the internal transcribed spacer(ITS)gene.E.bieneusi was detected in 16 out of 47(34.0%)fecal specimens examined.Sequence analysis of the ITS revealed six known genoty pes: Type Ⅳ(4),EbpC(4),EbpA(4),BEB6(2),COS-Ⅰ(1),and COS-Ⅱ(1).Of these,Type Ⅳ,EbpC,and EbpA are known to cause human microsporidiosis worldwide,whereas the remaining genotypes are generally specific to ruminants.The present study indicated that Pere Davids deer are naturally infected with E.bieneusi,predominantly with zoonotic genotypes,and may pose a risk for human transmission.
