了解云南省部分猪场猪瘟发病情况,为猪场制订合理的防控规程提供依据,采用RT-PCR方法对2013—2015年间云南省部分猪场1 055份样品进行了猪瘟病毒(CSFV)的病原检测。结果表明:2013—2015年猪瘟病毒阳性率分别为7.20%、17.65%、12.26%,三年间猪瘟参与混合感染占总混合感染的比例分别为37.5%、46.4%、67.4%。说明在云南省境内部分猪场猪瘟的发病率仍然很高,有的猪场甚至在使用疫苗后仍然发病。
To understand the incidence of swine fever in some pig farms in Yunnan Province and provide the basis for the development of reasonable prevention and control procedures in pig farms. RT-PCR was used to analyze the prevalence of swine fever virus (CSFV) in 1 055 samples of some pig farms in Yunnan Province between 2013 and 2015, Pathogen detection. The results showed that the positive rates of classical swine fever virus in 2013-2015 were 7.20%, 17.65% and 12.26%, respectively. The proportion of classical swine fever to mixed infection in the three years was 37.5%, 46.4% and 67.4% respectively. This shows that the incidence of CSFV in some farms in Yunnan Province is still very high, and some pigs are still infected even after using the vaccine.
