Abstract
Forty nine strains of H3N2 subtype swine influenza viruses identified by specific Reverse Transcription-PCR Method which were isolated from the swine in Chongqing, China during the 2010 to 2011. NS1 genes of these strains were sequenced and analyzed with the representative strains published in GenBank. The results indicated that the NS1 genes of these strains and the A/swine/Guang Dong/811/2006(H3N2) and Influenza A virus (A/swine/Colorado/1/1977(H3N2)), A/Netherlands/233/1982(H3N2), A/swine/Heilongjiang/1/ 05(H3N2) and A/swine/Fujian/F2/2007(H3N2) displayed nucleotide homologies nearly 99%. These results suggested that the strains might be derived from human influenza.
