1981年12月至1882年7月在广东省珠江三角洲调查家鸭感染流感病毒的情况。共收集到当地饲养的鸭咽拭子和泄殖腔拭子292份,分离到甲型流感病毒24株,阳性率为8.22％。经琼脂双扩散试验证实A/鸭/广东/248/82和A/鸭/广东/249/82病毒为甲型流感病毒,经血球凝集抑制和神经氨酸酶抑制试验证实这两株病毒的表面抗原为H_1N_4(Hsw_1Nav_4),经交叉血凝抑制试验鉴定这两株病毒的Hsw_1与A/Swine/Iowa/15/30以及A/New Jersey/8/76病毒抗原性有明显差异。具有Hsw_1血凝素的流感病毒在我国尚未见报告。本文讨论了这两株病毒在流感病毒生态学中的意义和家鸭在人类流感病毒新亚型起源中的作用。
December 1981 to July 1882 in the Pearl River Delta in Guangdong Province to investigate the duck infected with influenza virus situation. A total of 292 duck swabs and cloacal swabs were collected and 24 strains of influenza A virus were isolated, the positive rate was 8.22%. Agar double diffusion test confirmed A / duck / Guangdong / 248/82 and A / duck / Guangdong / 249/82 virus as influenza A virus, hemagglutination inhibition and neuraminidase inhibition test confirmed that the two virus surface The antigen was H_1N_4 (Hsw_1Nav_4). The antigens of Hsw_1, A / Swine / Iowa / 15/30 and A / New Jersey / 8/76 were identified by cross-hemagglutination inhibition test. Influenza virus with Hsw_1 hemagglutinin has not been reported in our country. This article discusses the significance of the two viruses in influenza virus ecology and the role of house ducks in the origin of the new subtype of human influenza virus.
