ABSTRACT

Classical swine fever (CSF) is a major hazardous disease to the pigs and as a dangerous epidemic; it causes a serious economic losses to the pig industry. Though, a national compulsory immunization of CSF vaccines had been carried out for a long time, scarce information can be got about the immune effect of CSF in Tibetan pigs. The present study was to investigate the seroprevalence of CSF in Tibetan pigs in Nyingchi area of Tibet, China. A total 454 samples were collected from November 2014 to January 2015 and were investigated through enzyme-linked immuno sorbent assay (ELISA). The results showed that 241 (53.1%, 95% CI 48.4-57.8) pigs were found to be positive for CSF with the further distribution of 53.3% (95% CI 46.8–59.6), 49.5% (95% CI 42.2-56.8) and 93.8% (95% CI 69.8-99.8) in Tibetan counties of Nyingchi, Mainling and Gongbo’gyamda, respectively. There was no significant difference in male (52.8%, 95% CI 46.4-59.1) and female pigs (50.0%, 95% CI 42.6-57.4). Though, 53.1% of  the serum samples were tested out positive to CSF, only the seroprevalence of CSF in Tibetan pigs in Gongbo’gyamda were higher than 70% which was ruled by the government. The low seroprevalence of CSF in Tibetan pigs should arise a serious concern and effective methods should be taken, in order to prevent CSF infection effectively.
