中国畜牧兽医2013年第40卷第2期犬流感(H3N2亚型)血清学调查

为了解广东地区犬流感(CI)流行情况,以期为犬流感的预防提供参考依据,本研究采用ELSIA方法及血凝抑制试验(HI),对广东省内6地市的1440份犬血清样品进行抗体检测。结果显示,1440份犬血清中犬流感抗体平均阳性率为7.92%(ELISA)和6.25%(HI)。其中广州、深圳和惠州地区的犬流感抗体阳性率较高。1～3岁犬的犬流感抗体阳性率高于其他年龄段犬,雄性犬犬流感抗体阳性率高于雌性。结果表明,H3N2亚型犬流感病毒在广东局部地区流行。鉴于当前在部分地区CIV阳性率较高,结合CIV在犬群中迅速传播的流行特点,要避免CIV暴发流行及对人类的健康造成威胁,对于CIV的防制应结合当地实际情况,制定切实有效的防制措施。

Serological Investigation on Infection Canine Influenza Virus (H3N2)

To evaluate epidemic station of canine influenza virus infection in Guangdong, and provide reference basis for the prevention of canine influenza, 1440 canine serum samples from six different cities in Guangdong province were detected for the level of antibody by enzyme-linked immunosorbent assay (ELISA) and hemagglutination inhibition (HI) assay. The results showed that the average positive rates were 7.92% (ELISA) and 6.25% (HI), and the levels of antibody in Guangzhou, Shenzhen and Huizhou were higher than the other regions. The positive rate was highest in canines of 1 to 3 years old, and the morbidity of the canine influenza was higher in male canines. The results demonstrated that canine influenza virus infection was prevalent in parts of area of Guangdong and avian origin canine influenza virus H3N2 stubtype was the main type.
