Changes in body weight. Body weight (a) and mortality (b) in BALB/c mice inoculated with strains A and B of H6 viruses. a Body weights and survival rates of mice were observed over 14Â days after infection. b Lungs and trachea were collected at 3Â days post infection (p.i.), and virus replication levels were measured by EID50 values in specific-pathogen-free (SPF) eggs
