Epidemiological Investigation of PR and Study on Prevention and Control Measures in Chuxiong Region of Yunnan Province
摘要
Abstract
In order to understand the infection status of PRV wild isolate in the farms located in Chuxiong region from 2009 to 2013,the PRV serum antibodies of 2 811 serum samples from different batches collect-ed from different scale immunized farms of Chuxiong regain were detected by PRV gE-ELISA antibody de-tection kit.Prevention and control measures were taked in 4 farms.The serological survey result showed that 758 farms were detected and the positive rate was 31.70%.The average positive rates of commercial pigs and boars were 26.34% and 35.06% respectively.The positive rates of scale farms and scattered farms were 37.67% and 28.62% respectively.The positive rate of PR in sows were 56.82% (un-vaccinated), 45.16% (once vaccinated),29.41% (twice vaccinated )and 18.33% (three vaccinated).The positive rate of PR in un-vaccinated sows were higher than the rate of once vaccinated,twice vaccinated and three vacci-nated.After taking the prevention and control measures 12 months,the positive rate of PR apparently de-clined.The result showed that the infection of PRV wild isolate were widespread in Chuxiong region.En-hancing bio-safety,developing reasonable anti-epidemic systems and using by gene-deleted vaccine are effi-cient ways to control PR further spreading in farms.关键词
