江苏羊群各型流感病毒抗体的血清学检测与分析

The sero-epidemiological survey of different influenza subtypes in goat/sheep flocks in Jiangsu,China

为了解羊群是否存在流感病毒的感染,采用血凝抑制试验对江苏省7个县市不同羊场的2012—2014年323份羊血清中不同亚型(H1、H5、H7、H9)流感病毒抗体进行检测。结果显示,羊的H9亚型和H5亚型(Re-4株)抗体阳性率分别为95%和71.7%;H7亚型抗体阳性率为25.5%;甲型H1N1流感病毒抗体阳性率为14.7%;H5亚型(Re-5株和Re-6株)抗体阳性率均为0。结果表明,不同亚型流感病毒在羊群中均普遍存在,流行情况各有不同,应对其流行病学和公共卫生意义给予重视。

To investigate the epidemic situations of influenza virus in goats of Jiangsu province, a total of 323 serum samples in seven areas of Jiangsu from 2012 to 2014 were collected from goats and the antibodies against influenza virus HIN1, H5 （Re-4.Re-5.Re-6）, H7 and H9 subtypes were measured by heamoglutination inhibition （HI） test. The results indicated that the positive rates were 95%,71. 7%,25.5% and 14.7% against H9,H5 （Re-4）,H7 and HINlsubtype,respectively. No specific antibodies were detected for H5 （Re-5） and H5 （Re-6） subtypes. It showed that the influenza A viruses could infect goats in nature,and different subtypes of the viruses varied epidemic patterns significantly. It is necessary to pay more attentions to its significance in epidemiology and public health.
