Molecular detection and zoonotic genotyping of Enterocytozoon bieneusi in Siberian tigers (Panthera tigris altaica), Northeast China
Year: 2026
Type: article
Abstract: Enterocytozoon bieneusi is an important zoonotic pathogen. This study examined its prevalence and genotypes in Siberian tigers in Northeast China. Fecal samples from 97 captive and 5 wild tigers were analyzed by nested PCR targeting the ITS region. Prevalence in captive tigers was 40.2% (39/97), with no significant site differences. Three genotypes were identified: D (89.7%), Peru8 (7.7%), and Type IV (2.6%), all within zoonotic Group 1. E. bieneusi was detected for the first time in a wild Siberian tiger (genotype D). The predominance of genotype D-common in poultry-suggests dietary transmission through contaminated chicken meat. These results indicate high prevalence of zoonotic genotypes in tigers, underscoring cross-species transmission risks and the need for strengthened biosecurity and surveillance.
