Аннотация
Blastocystis sp. is a gastrointestinal pathogen that is frequently found in humans and animals worldwide. In this study, 201 fecal samples were collected from captive Alpine musk deer (Moschus chrysogaster) at three farms in Gansu province. Blastocystis was detected and subtyped by amplifying and sequencing the small subunit ribosomal DNA gene. The overall prevalence of Blastocystis was 39.8% (80/201). Five known Blastocystis subtypes (STs), including ST1 (n = 1), ST4 (n = 12), ST10 (n = 50), ST14 (n = 6), and ST24 (n = 11) were identified using subtyping and evolutionary analysis. ST10 was the most common ST observed in each farm. This study showed the infection status and genetic characteristics of Blastocystis in M. chrysogaster. Based on the surveyed data, because various potentially zoonotic STs, such as ST1, ST4, ST10, ST14, and ST24, were detected, it is believed that the zoonotic risk of Blastocystis from the Alpine musk deer in this area cannot be ignored.
