Abstract

This study was carried out to investigate the prevalence of pocine circovirus type 2(PCV2) infection and post-weaning multi systemic wasting syndrome(PMWS) of swine in Gyeongbuk province from June to December in 2003. Gyeongbuk Veterinary Service Laboratory had tested PCV1 and PCV2 by the PCR method against 210 infected pigs of 105 farms, which were requested diagnosis of disease and investigate compositive infections with bacterial disease. The following results were obtained; 1. Among 210 pigs, The pigs infected with PCV1 were 134(63.8%) heads and with PCV2 were 143(68.1%) heads. 2. Using PCR, the rate of PCV1 infection of 105 farms which were requested of diagnosis of disease is positive in 75(71.4%) farms and 78(74.3%) farms were positive in PCV2, and compositive infections of PCV1 and PCV2 were 75(71.4%) farms. 3. According to age of requested pig, the frequency of PCV infection rate was following, the pig under 4 weeks of age were 28.6% in PCV1 and PCV2, respectively, and the pig of 4-7 weeks of age were 58.6% in PCV1 and PCV2, respectively. The pig of 8-11 weeks of age were 73.1% in PCVl and 74.6% in PCV2, the pig of 12-18 weeks of age were 80.9% in PCV1 and 88.1% in PCV2. 4. In the distribution of compositive infection with bacterial disease related to PCV2 among requested samples, PCV2 infection was 39.7% in 78 cases, two kinds of compositive infection was 38.5%, three kinds of compositive infection was 18.1% and four kinds of complex infection was 3.9%.
