Mean body weight changes of control voles and voles infected with HPAI viruses. Body weight of bank voles intranasally inoculated with (A) 103.75 EID50/0.1 mL of Os/H7N1 virus and (B) 104.4 EID50/0.1 mL of Tk/H5N1 virus (group I-Tk/H5N1). Data shown are the mean ± SD (error bars) of body weight changes of inoculated voles in comparison to the control group. No significant difference (p > 0.05) was noticed between the body weight recorded at different points in all experimental groups.
