Objective:To study the infection rate of Chongqing duck hepatitis B virus(DHBV)in Chongqing and its seasonal difference in adult ducks
in order to optimize DHBV research model.Methods:560 serum specimens of Chongqing ducks were collected randomly from a duck farm in Spring and Summer of 2009.Duck hepatitis B virus DNA was detected by dot blotting
with DNA probe labelled with digoxigenin.Results:The infection rate of duck hepatitis B virus was 1.82% in Spring and 5.26% in Summer
with the lattre being significantly higher than the former(P<0.05).Conclusion:The infection rate of duck hepatitis B virus in Chongqing area is higher in Summer than that in Spring
but both are lower than that in other areas of China.
