The role of live bird markets (LBMs) in the perpetuation of avian influenza virus (AIV) has been well studied worldwide; however, there is a paucity of information on the prevalence of different AIV subtypes in LBMs in Eastern China. In this study, long-term surveillance was conducted to investigate the prevalence of AIV in chickens, ducks, and geese in an LBM in Yangzhou city, Jiangsu province, Eastern China, between July 2002 and May 2011. The study used primary virus isolation and subtype-specific reverse-transcription–PCR. In total, 23 different HA–NA subtype combinations were detected, mainly in domestic ducks. This result suggests that domestic ducks play a more important role in LBMs in Eastern China.
