Paratuberculosis or Johne’s disease (JD), caused by Mycobacterium avium subspecies paratuberculosis (MAP), is a chronic infectious granulomatous enteritis of ruminants and other animals, which has a worldwide occurrence, but little is known of MAP infection in domestic sika deer in Jilin Province, China. The objective of the present investigation was to examine seroprevalence and risk factors of MAP infection in Jilin Province. Serum samples collected from 1400 sika deer from 16 sika deer herds were collected in the 4 districts of the province between May 2013 and August 2014 and were tested independently for the presence of antibodies against MAP. A total of 247 (17.64 %) sika deer tested positive for MAP antibodies using a commercially available enzyme immunoassay kit. The management level of farm and collecting region of sika deer was the main risk factor associated with MAP infection. The present study revealed the seroprevalence of MAP infection in sika deer in Jilin Province, China, which provided the baseline data for taking comprehensive countermeasures and measures in effectively preventing and controlling MAP infection in sika deer.
