2019—2022年河池市屠宰猪群主要疫病监测分析

Monitoring analysis of major epidemicdiseases in slaughtered pigs in Hechi City during 2019 to 2022

研究旨在了解河池市屠宰猪群主要疫病感染情况,于2019—2022年采集屠宰猪群组织混合样品,应用实时荧光定量RT-PCR检测猪繁殖与呼吸综合征病毒(PRRSV)、猪瘟病毒(CSFV)、口蹄疫病毒(FMDV)、猪塞内卡病毒(SVA),应用荧光PCR检测圆环病毒2型(PCV2)、圆环病毒3型(PCV3)、伪狂犬病毒(PRV)。结果显示,检测的1745份样品中,除FMDV和PRV没有检出外,其余5种病原均有检出,样品总体阳性率由高到低依次为42.87%(PCV2)、11.63%(PCV3)、8.48%(PRRSV)、0.80%(CSFV)、0.80%(SVA);县区检出率依次为100.00%(PCV2)、100.00%(PRRSV)、90.91%(PCV3)、54.55%(CSFV)、27.27%(SVA);5种病原存在不同程度的混合感染。研究表明,圆环病毒病、猪繁殖与呼吸综合征和猪瘟在河池市及其周边地区猪群中流行普遍,需进一步加强监测和做好防控措施。

The aim of the study was to understand the infection situation of major diseases in slaughtered pigs in Hechi City.Mixed samples of slaughtered pig tissues were collected from 2019 to 2022,and real-time fluorescence quantitative RT-PCR was used to detect PRRSV,CSFV,FMDV and SVA.PCV2,PCV3 and PRV were detected by fluorescent PCR.The results showed that in 1745 samples,except for FMDV and PRV,the other five pathogens were detected.The overall positive rate of samples was 42.87%(PCV2),11.63%(PCV3),8.48%(PRRSV),0.80%(CSFV),0.80%(SVA)in order from the highest to the lowest.The detection rates were 100.00%(PCV2),100.00%(PRRSV),90.91%(PCV3),54.55%(CSFV),27.27%(SVA),respectively.The five pathogens had mixed infection to different degrees.The study indicates that circovirus disease,porcine reproductive and respiratory syndrome and swine fever are prevalent in the pig population in Hechi City and its surrounding areas,and further surveillance and prevention and control measures should be strengthened.
