ABSTRACT

Objective:

To investigate the infection rate and genotype distribution of Enterocytoon (E.) bieneusi in farmed black goats from the Hainan Province, China.

Methods:

A total of 341 fresh fecal samples were collected from black goats farmed in five different locations of the Hainan Province, China. E. bieneusi was examined and genotyped through PCR and sequencing analysis of the internal transcribed spacer (ITS) region of this pathogen.

Results:

The average prevalence of E. bieneusi in black goats from from the five locations was 24.0% (82/341) ranging from 6.3% (4/63) to 37.2% (32/86) (χ2 =17.252, P<0.01). The detected 82 E. bieneusi isolates belonged to eight ITS genotypes including six known genotypes (AHG1, CHG2, CHG3, CHG5, CM21 and D) and two novel genotypes (HNG-Iand HNG-II). Amongst the genotypes, CHG5 was the the most prevalent with a prevalence of 57.3% (47/82), followed by CHG3 (28.0%, 23/82), CHG2 (4.9%, 4/82), CM21 (3.7%, 3/82), D (2.4%, 2/82), AHG1 (1.2%, 1/82), HNG-I(1.2%, 1/82) and HNG-II(1.2%, 1/82). In those genotypes, only genotype D was found in humans previously.

Conclusions:

This represents the first report identifying E. bieneusi in black goats from Hainan Province of China. The results indicate that E. bieneusi has a high prevalence and a wide distribution in those animals from Hainan Province, but the risk of zoonotic transmission of E. bieneusi from them to human is low.
