| Research Abstract |
A total of 4,526 samples were collected from pigs, ducks and chickens, in winter seasons of 2009-2011, in farms in Hanoi. Of those, influenza A-specific M gene was detected in 52% (342/659) and in 29% (761/2,669), and 39% (468/1,198) the samples taken from pigs, ducks, and, chicken in the seasons, from which H6N1 and H9N2 subtypes of Avian influenza viruses were isolated. Phylogenetic analyses revealed that these two subtypes carried genes close to those isolated in South Korea, as well as in east southern China or in northern Japan, indicating that AIVs circulating among ducks in northern Vietnam were possibly introduced by wild birds migrating along with the East Asian flyway.
