Epidemiological investigation and risk factors of Peste des petitis ruminants (PPR) in yaks (Bos grunniens) and cattle in five regions of China

ABSTRACT

@#To investigate the prevalence of Peste des petitis ruminants in yaks and cattle in poorly studied areas of China. A total of 1202 and 560 blood samples were collected from yaks and cattle, respectively and processed using a commercial ELISA kit. Multivariable logistic regression model was piloted to find the variables, potentially associated with exposure of PPR infection in yaks and cattle. Results indicated that the overall prevalence of PPR in yaks was 11.2%. A total 66 (11.8%) out of 560 were examined out to be positive to PPR in cattle in Jiangxi province. According to conditional stepwise logistic regression, region, age and gender were found to be the more influencing risk factors in yaks, while region and age were found to be the potential risk factors in cattle. The current results reported the prevalence and associated risk factors of PPR in bovine for the first time in China.
