| Abstract: |
| 1979~1980年在广州郊区采集当地饲养的鸭咽拭子和/或泄殖腔拭子132份 (371只鸭), 分离到8株甲型流感病毒, 阳性率为6.1%. 经血凝抑制和神经氨酸酶抑制试验鉴定, 这8株病毒的表面抗原组合分为五种方式: Hav6 Nav4、Hav7 Neq2、Hav6Nav5、Hav6Nav 6、Hav8 N2,其中Hav8 N2的结合方式未见有报道. 8株病毒的血凝素分为三个亚型 (HaV6、HaV7、HaV8)神经氨酸酶分为五个亚型 (NaV4、NaV5、Nav6、Neq2、N2). 上述结果说明广州郊区的鸭是甲型流感病毒的重要自然宿主, 这对研究人类流感病毒新亚型的起源以及控制流行有重要的意义. |

| In 1979-1380, 132 samples of throat swab and/or cloacal swab were collected from 371 locally raised ducks in the suburbs of Guangzhou (canton). Eight strains of influenza A virus were isolated and the prevalence rate was 6.1%. After identification by haemagglutiaation-inhibition and neuraminidase-inhibition tests, the surface antigen combinations of the 8 strains could be divided into five types, namely, Hav6Nav4, Hav7 Neq2, Hav6Nav5, Hav6Nav6, Hav8N2, the last being a new type never reported before.The haemaeglutinins of the 8 strains could be divided into three subtypes: Hav6, IIav7, Hav8, and their neuraminidases could be divided into five subtypes: Nav4, Nay5, Nav6, Ncq2, N2. The above results showed that the ducks in Guangzhou suburbs may be an important natural host of human influenza A virus.These findings are of considerable importance and significance in tracing the origin of a new subtype of human influenza virus aad in its control. |
