摘要： Swine influenza is a common infectious respiratory disease of pigs that caused by influenza A viruses, and H1N1 and H3N2 are currently the most popular subtypes of influenza viruses circulated in pig population in China. H9N2 virus was detected from pigs that imported from Mainland China in Hong Kong in 1998, and extensive viral surveillance conduced since then indicated that H9N2 viruses are widely distributed in pig population in China. Phylogenetic analysis indicated that H9N2 viruses from pigs are highly related, implying they may establish a stable lineage in pigs in China. During the routine surveillance, we also isolated 2 H5N1 viruses from pigs in Fujian province in 2001 and 2003, respectively. Molecular analysis indicated that the two viruses are origin from duck H5N1 viruses. Their replication in chickens, mice and pigs has also been investigated.
