Abstract

During 1969 type A influenzaviruses were isolated from three outbreaks of disease among domestic ducks in Hong Kong. The isolates were characterized in haemagglutination inhibition and neuraminidase inhibition tests with antisera to prototype avian and human influenza strains. A/duck/Hong Kong/46/69 and 120/69 contained haemagglutinin and neuraminidase antigens related to those of A/turkey/Wisconsin/66. The neuraminidases of these Hong Kong isolates, like that of turkey/Wisconsin/66, were antigenically closely related to those of human Asian influenzaviruses. A/duck/Hong Kong/826/69 contained haemagglutinin and neuraminidase antigens related to those of chicken/Scotland/59 and tern/South Africa/61, respectively. The duck influenza A isolates represent the first viruses of their antigenic variety to be isolated in South-East Asia. The possible epidemiological significance of the duck/Hong Kong/69 strains is discussed.

摘要

1969年期间,从香港家鸭的三次疾病暴发中分离出甲型流感病毒。使用针对禽类和人流感原型毒株的抗血清,通过血凝抑制试验和神经氨酸酶抑制试验对分离株进行了鉴定。A/鸭/香港/46/69和120/69含有与A/火鸡/威斯康星/66的血凝素和神经氨酸酶抗原相关的抗原。这些香港分离株的神经氨酸酶,与火鸡/威斯康星/66的神经氨酸酶一样,在抗原性上与亚洲人流感病毒的神经氨酸酶密切相关。A/鸭/香港/826/69分别含有与鸡/苏格兰/59和燕鸥/南非/61的血凝素和神经氨酸酶抗原相关的抗原。鸭甲型流感分离株是东南亚分离出的具有其抗原类型的首批病毒。讨论了鸭/香港/69毒株可能的流行病学意义。
