Abstract

Parasitic nematodes of Oesophagostomum spp., commonly known as ‘nodular worms’ are one of the most widely distributed and prevalent emerging zoonotic nematodes. However, little is known about the prevalence and gene characteristics of those parasites in Tibetan pigs. Therefore, a study was carried out to investigate the prevalence, isolation and identification of Oesophagostomum spp from Tibetan pigs by genetic markers of nad1,cox3 and ITS1 for the first time. The results revealed that the infection rate of O. dentatum and O. quadrispinulatum by genetic markers of nad1 was 81.13%; 35 (66.04%); the O. dentatum and O. quadrispinulatum by genetic markers cox3 was 66.04%, and O. dentatum and O. stephanostomum by genetic markers ITS1 was found to be 77.36%. Interestingly, the O. stephanostomum specie was identified and isolated from 90.48% stomach and 69.23% colon samples by genetic markers of ITS1. The present study, for the first time has described the presence and genetic characterization of Oesophagostomun spp of O. dentatum, O. quadrispinulatum and especially O. stephanostomum in Tibetan pigs from the high and remote Tibetan plateau. A public concern should be raised in terms of economical losses and severe public health problem.
