Abstract:Objective To investigate the prevalence of avian influenza in birds in the flower & bird markets in Beijing, and to provide basic evidence for prevention and control of influenza. Methods An influenza surveillance was carried out in two bigger flower & bird markets in Beijing, and 161 anal samples were obtained from 100 sparrows, 50 swallows, 10 pigeons, and one parrot. Their virus isolation was performed in SPF embryonated chicken eggs. Result No avian influenza virus was isolated from these bird samples. However, Newcastle disease virus was detected in one pigeon, and avian paramyxovirus type 2 was isolated in tree sparrows. Conclusions The basic data of epidemiological evidence of avian influenza is obtained from flower & bird markets in Beijing. H7N9 influenza virus has not been detected in birds in two flower & bird markets in Beijing. The data are helpful for prevention and control of influenza.
