摘要
[目的]调查安徽省猪圆环病毒的感染情况。[方法]2018年,采用荧光定量PCR方法对来自安徽省3个地区12个猪场健康猪群的239份扁桃体样品进行了PCV2和PCV3检测。[结果]PCV2个体阳性率为67.4%(161/239)、群体阳性率为91.7%(11/12),PCV3个体阳性率为14.6%(35/239)、群体阳性率为58.3%(7/12),PCV2/PCV3混合感染个体阳性率为5.0%(12/239)、群体率阳性为41.7%(5/12)。不同生长阶段、不同地区和不同规模的生猪PCV2、PCV3及PCV2/PCV3混合感染存在差异。育肥猪PCV2感染率最高(84.3%),能繁母猪PCV3感染率(51.9%)及PC2/PCV3混合感染率(14.8%)最高;C地区PCV2感染率最高(89.9%),B地区PCV3感染率(36.2%)及PC2/PCV3混合感染率最高(8.8%);中型猪场PCV2感染率最高(82.2%),大型猪场PCV3感染率(38.3%)及PC2/PCV3混合感染率最高(10.0%)。[结论]安徽省猪群中存在PCV2和PCV3流行,需引起足够重视。
[Objective]To investigate the infection status of porcine circovirus in Anhui Province.[Method]In 2018,239 tonsils samples were collected from 12 healthy pig herds in A,B and C regions of Anhui Province to detect the infection situations of PCV2 and PCV3 by real-time PCR.[Result]The individual detection rate(IDR)of PCV2 was 67.4%(161/239 in overall samples,and IDR of PCV3 was 14.6%(35/239),and the mixed IDR of PCV2/PCV3 was 5.0%(12/239).The herd detection rate(HDR)of PCV2 was 91.7%(11/12)in overall pig farms,HDR of PCV3 was 58.3%(7/12),and the mixed HDR of PCV2/PCV3 was 41.7%(5/12).PCV2,PCV3 and PCV2/PCV3 mixed infection had difference in different scales of pig farms in different regions at different stages.Fattening pigs had the highest IDR of PCV2(84.3%),and fertile sows had the highest IDR of PCV3(51.9%)and mixed IDR of PC2/PCV3(14.8%).Region C had the highest IDR of PCV2(89.9%),and region B had the highest IDR of PCV3(36.2%)and IDR of PCV2/PCV3(8.8%).Medium-scale pig farms had the highest IDR of PCV2(82.2%),and large-scale pig farms had the highest IDR of PCV3(38.3%)and IDR of PCV2/PCV3(10.0%).[Conclusion]There were PCV2 and PCV3 prevalence in Anhui Province,and we should paid more attentions to it.
