Abstract

Blastocystis spp., Enterocytozoon bieneusi and Encephalitozoon spp. are prevalent zoonotic gastrointestinal parasites that cause severe diarrhoea and enteric diseases in humans and animals worldwide. This study investigated the molecular occurrence, genetic diversity and zoonotic potential of E. bieneusi, Blastocystis spp. and Encephalitozoon spp. in domestic hair goats in Central Anatolia.
A total of 300 faecal samples were collected from hair goats in Kayseri, Aksaray and Sivas Provinces and genomic DNA was extracted from these samples. The presence of the three pathogens was detected using PCR and nested PCR targeting the SSU rRNA for Blastocystis spp., the internal transcribed spacer (ITS) for E. bieneusi and Encephalitozoon spp., respectively. Positive PCR products were sequenced to determine the species, subtypes and genotypes of the pathogens.
The overall prevalence rates of E. bieneusi and Blastocystis spp. were 5.3% (16/300) and 6.7% (20/300), respectively. None of the faecal samples tested was positive for Encephalitozoon spp. and no co-infections among these three pathogens were detected. The SSU rRNA sequence analysis revealed Blastocystis spp. ST10, a subtype predominantly associated with animals. Additionally, one known E. bieneusi genotype (BEB6) was identified. The BEB6 genotype falls into zoonotic Group 2 of E. bieneusi in the phylogenetic tree.
Our study is the first report of Blastocystis spp. and E. bieneusi infection in hair goats in Türkiye, highlighting their potential role in zoonotic transmission within a One Health framework. Our results provide scientific data for the prevention and control of these two intestinal pathogens. Further investigations are necessary to better understand their genetic characteristics and zoonotic potential in Türkiye.
