【摘要】 在我国家鸭和野鸭中,正粘与副粘病毒普遍存在,类型复杂。正粘病毒在家鸭中主要是Hav₄Nav₁,野鸭中则为Ha₇Neq₂.共分离到30种不同血凝素和神经氨酸酶组合的毒株,包括近几年发现的Hav_?Hav₁₀和Nav₆。在鸭群中,含有Hav₇和N₂毒株的普遍存在,以及H₂和N₁一类毒株的出现,不仅进一步证实了人流感病毒与动物流感病毒之间有共同抗原,而且有助于解释为什么近几次人流感病毒新亚型均首发于我国或附近地区。更多还原

【Abstract】 Surveys on orthomyxoviruses and paramyxoviruses in domestic and feral ducks in China during 1978-1980 were reported. Results indicated that these viruses had a wide distribution in domestic and feral ducks with a great diversity in subtypes. Orthomyxoviruses most frequently isolated from domestic ducks were Hav4Nav1 and from feral ducks were Hav7Neq2. A total of 30 different combinations of hemagglutinin and neuraminidase subtypes were found, including nine different hemagglutinins and ten neuraminidases. Some of them had just been discovered recently, for example, Hav9, Hav10 and Nav6. Orthomyxoviruses possessing Hav7 or N2 were found frequently in Chinain domestic and feral ducks and viruses containing H2 or N2 were also isolated. Results suggested that there was a close relationship between human and avian influenza viruses and might help to explain why several new subtypes of human influenza virus were first detected in China or her vicinity.1.Institute of Virology, Chinese Academy of Medical Sciences;2.Sanitation and Antiepidemic Station of Liaoning Province;3.Sanitation and Antiepidemic Station of Dandong City.更多还原
