Epidemiological survey of fasciolosis in yaks and sheep living on the Qinghai-Tibet plateau, China

摘要

Fasciolosis is one of the biggest threats to livestock and human population. For this purpose, the seroprevalence of Fasciola hepatica was investigated in yaks and sheep living on the Qinghai-Tibet plateau, China by piloting commercial ELISA kits. A total of 3276 yaks and 1092 sheep were incorporated in this study. The prevalence of the parasite in yaks and sheep was 38.3% and 26.4%, respectively. The serological results revealed a relatively high prevalence of F. hepatica infection in yaks and sheep, respectively. The present study may greatly contribute to the prevention of this parasitic zoonosis and great importance should be given to the potential threat caused by F. hepatica in this special plateau.
