用血凝抑制,单扩溶血和神经氨酸酶活性抑制测定均证实了,我国贵州猪群中确含有甲_2型(H_2N_2)流感病毒的抗体。据我们所知,至今除人外,其它哺乳类动物是否能被甲_2型病毒自然感染还不清楚。猪群中甲_2型抗体的发现说明了人甲_2型流感病毒起源于动物的可能性是存在的,指出了在人群中已消失10余年之久的甲_2流感病毒,在猪群中仍存在着,同时还指出了甲_2型流感病毒将来从猪又回到人群中来并造成流行,这种可能性是存在的。很有意义地发现了炎热的夏天(6～8月)
With hemagglutination inhibition, monoheparin and neuraminidase inhibition assays were confirmed, Guizhou Guizhou pigs indeed contain a _2 type (H_2N_2) influenza virus antibodies. To the best of our knowledge, it is unclear whether other mammals can naturally be infected by a type 2 virus, except humans. The discovery of A-2 antibody in swine herpes shows that there is a possibility that human Influenza A (A) -2 virus originated in animals, and pointed out that A-2 influenza virus which has disappeared in the population for more than 10 years has been reported in swine herds There is still a possibility that at the same time, it is pointed out that the A-2 influenza virus will return to the crowd and cause epidemics in the future. It is meaningful to find the hot summer (June to August)
