31、On rare occasions, avian influenza viruses have crossed the species barrier to infect humans.
32、Piezoelectric immunity protein chips for determination of H5,H9 subtype avian influenza viruses
33、Evolutionary characteristics of hemagglutinin genes of H5N1 subtype avian influenza viruses from boundary region of Yunnan Province
34、Neuraminidase gene reassortment of low pathogenic avian influenza viruse N2 subtype among domestic ducks in Eastern China
35、Analysis of the hemagglutinin genes of four avian influenza viruses of H9N2 subtype isolated from northern China
36、It is possible that there could be two separate avian influenza viruses, one containing H5 and the other containing N1.
37、All evidence to date suggests that isolated instances of limited, unsustained human-to-human transmission can be expected from avian influenza viruses in humans.
38、H5N1 appears to have expanded its host range, infecting and killing mammalian species previously considered resistant to infection with avian influenza viruses.
39、Etiological examination on the low pathogenicity avian influenza viruses with different HA subtypes from poultry isolated in eastern China from 2006 to 2008
40、Although natural hosts are birds, the avian influenza viruses are known to cross species barriers to infect other mammals, including humans.
41、H9N2 subtype avian influenza viruses (AIV) have widely spreaded in the world. It has made not only huge economic losses for poultry industries but damage for human being's health.
