  1. aSix-week-old female BALB/c mice were inoculated intranasally with 106 EID50 of H9N2 influenza viruses. Three mice from each group were killed on 3 dpi and 5 dpi and virus titers in samples of heart, liver, spleen, lung and brain were determined. bThe average virus titer was expressed as log10EID50/ml ± SD(positive number/total number), with the limit of virus detection at 1.2 log10 EID50/ml. c— indicates that virus was not recovered from the sample.
