新疆部分规模化养猪场中猪圆环病毒2型和3型监测
Monitoring of Porcine circovirus(PCV)types 2 and 3 in some large-scale pig farms in Xinjiang
摘要
Abstract
[Objective]To investigate the prevalence of Porcine circovirus type 2(PCV2)and Porcine circovirus type 3(PCV3)in Xinjiang.[Methods]From October 2022 to September 2023,1403 samples from 7 large-scale pig farms were detected and sequenced by fluorescent quantitative PCR.[Results]The o-verall positive rate of PCV2 was 3.20％(45/1403),the overall positive rate of PCV3 was 33.00％(463/1403),and the combined infection rate of PCV2 and PCV3 was 7.84％(11/1403).The positive detection rate of PCV2 and PCV3 in C field was the highest,with PCV2 7.46％(10/134),PCV3 64.18％(36/134),and PCV2 and PCV3 mixed infection rate 3.73％(5/134).The positive rate of PCV2 and PCV3 was the high-est,and the positive rate of PCV2 was 4.78％(25/523).The detection rate of PCV3 was 57.36％(300/523).The detection rates of PCV2 and PCV3 were high in all seasons,and the PCV3 strain was PCV3b and PCV3c.[Conclusion]PCV3 infection has been found in some large-scale pig farms in Xinjiang and the prevalence rate of PCV3 is much higher than that of PCV2,and PCV3 strain is PCV3b and PCV3c.关键词
