英文摘要	BackgroundGastrointestinal nematodes (GINs) have seriously affected the production and earnings of animal husbandry in various countries, while some species of GINs infect humans. At present, little is known about the species and prevalence of GINs in Qinghai-Tibetan Plateau (QTP).MethodsIn this study, 528 fresh faecal samples were collected from typical areas in different altitudes with seven species of livestock in Qinghai, Tibet, Gansu and Yunnan Provinces. ITS-2 rRNA gene of nematodes was employed to detect by PCR and sequencing analysis. Phylogenetic analysis of related sequences was performed using MEGA 6.0 software.ResultsThe overall prevalence of GINs was 80.3% with 20 species of GINs detected, while Teladorsagia circumcincta was the dominant one, and four of which were zoonotic species such as Trichostrongylus colubriformis, Trichostrongylus axei, Trichostrongylus vitrinus and Oesophagostomum stephanostomum.ConclusionThe study provided panoptic information on the prevalence and species diversity of GINs in QTP area, which is useful and valuable for reference of measure formulation in livestock husbandry and public health concerns. The parasites of T. circumcincta, Cylicocyclus nassatus, Strongylus edentatus, Cylicostephanus longibursatus, Telephlebia brevicauda, Cyathostomum catinatum, Mecistocirrus digitatus, Cooperia punctata, Cylicodontophorus bicoronatus, Nematodirus oiratianus and Oesophagostomum asperum were firstly reported the presence in QTP area. The study also showed that horse could be infected by T. circumcincta, goat could be infected by C. nassatus, cattle could be infected by S. edentatus and C. bicoronatus,and O. stephanostomum could infect yak, cattle and Mongolian sheep in worldwide. Nevertheless, more investigations are needed, such as microscopic examination, to accurately determine the species in the region. 1. Provided panoptic information on the prevalence and species diversity of GINs in QTP of China.2. Some gastrointestinal nematodes that have not been reported in this area were detected.3. O. stephanostomum, T. circumcincta, C. nassatus, S. edentatus and C. bicoronatus can transmit cross-species.image
