    摘要:

    为了解广西玉林市鸭圆环病毒(duck circovirus,DuCV)感染情况,通过PCR方法,对2016—2019年玉林市629个养鸭场送检的856份病死鸭样品进行DuCV病原检测,并对检测结果进行不同月份、不同日龄以及混合感染情况统计分析。结果显示:2016—2019年玉林市送检病死鸭的DuCV检出率为10.63%(91/856),其中20日龄以内、21~65日龄、65日龄以上的检出率分别为7.76%、15.38%、11.32%;2019年(14.52%)和2018年(16.33%)的检出率高于2017年(5.82%)和2016年(2.38%);3—5月(13.15%)和上年12月—2月(11.88%)的检出率高于6—8月(4.35%)和9—11月(8.56%);95.60%(87/91)的DuCV阳性样品中检出副黏病毒、禽多杀性巴氏杆菌、鸭疫里默氏杆菌。结果表明:玉林市养鸭场中存在一定水平的DuCV流行,春冬季DuCV感染率较高,各日龄段鸭均易感,DuCV易与其他病毒和细菌发生混合感染。结果提示,要加强春冬季节DuCV感染的预防,采取综合防控措施,控制混合感染。

    Abstract:

    In order to investigate the infection status of duck circovirus(DuCV)in Yulin City of Guangxi Zhuang Autonomous Region,856 samples from diseased and dead ducks delivered by 629 duck farms from 2016 to 2019 were detected by PCR assay,and the results were statistically analyzed from the aspects of different months,different day-old ducks and the status of mix infection. The results showed that the detection rate of DuCV was 10.63%(91/856),among which,the detection rates were 7.76%,15.38% and 11.32% for ducks at the ages of less than 20 days old,21 to 65 days old and above 65 days old respectively;the detection rates in 2019(14.52%)and 2018(16.33%)were all higher than those in 2017(5.82%)and 2016(2.38%);the detection rates in March to May(13.15%)and in December last year to February were higher than those in June to August(4.35%)and in September to November(8.56%);Paramyxovirus,Pasteurella multocida and Pasteurella multocida were detected out from 95.60%(87/91)DuCV positive samples. It was concluded that DuCv was prevalent in the farms in Yulin City to some extent,especially in spring and winter,all ducks were susceptible,and mixed infection of DuCV with other viruses and bacteria occurred usually. Therefore,it was necessary to strengthen the prevention of DuCV infection in spring and winter and to control mixed infection by taking comprehensive measures.
