Prevalence and molecular identification of gastrointestinal nematodes in Qinghai-Tibetan Plateau of China.

The 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.
