title: Seroprevalence and Risk Factors of Fascioliasis in Yaks,Bos grunniens, from Three Counties of Gansu Province, China.
abstract: The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks,Bos grunniens, from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies againstFasciola hepatica. The overallF. hepaticaseroprevalence was 28.7% (454/1,584), with 29.2% in white yaks (284/974) and 27.9% in black yaks (170/610). The seroprevalence ofF. hepaticain yaks from Tianzhu, Luqu, and Maqu was 29.2%, 22.6%, and 29.5%, respectively. Female yaks (30.9%) had higherF. hepaticaseroprevalence than male yaks (23.4%). Also,F. hepaticaseroprevalence varied by different age group from 24.1% to 33.8%. Further, the seroprevalence ranged from 21.8% to 39.1% over different seasons. Interestingly, the season and age of yaks were associated withF. hepaticainfection in yaks in the investigated areas. These findings provided a basis for further studies on this disease in yaks from 3 counties of Gansu Province in northwestern China, which may ultimately support the development of effective control strategies of fascioliasis in these areas.
