Abstract :
The circulation and infection of avian influenza virus(AIV) in zoos and backyard flocks
has not been systematically investigated. In the present study, we surveyed the birds
including those in live bird markets(LBMs) and evaluated co-circulation of AIVs among
them. Overall, 26 H9N2 AIVs and one H6N2 AIV were isolated from backyard flocks
and LBMs, but no AIVs were isolated from zoo birds. Genetic analysis of the HA and
NA genes indicated that most of the H9N2 AIVs showed higher similarities to AIVs
circulating in domestic poultry than to those in wild birds, while the H6N2 AIV isolate
from an LBM did to AIVs circulating in migratory wild birds. In serological tests,
15%(391/2619) of the collected sera tested positive for AIVs by competitive-ELISA.
Among them, 34%(131/391) of the sera tested positive for AIV H9 antigen by HI test,
but only one zoo sample was H9 positive. Although AIVs were not isolated from zoo
birds, the serological results indicated that infection of AIVs might occur in zoos. It
was also confirmed that H9N2 AIVs continue to circulate and evolve between backyard
flocks and LBMs. Therefore, continuous surveillance and monitoring of these flocks
should be conducted to control further epidemics.
