Different inbred laboratory mouse strains exhibit variable kinetics of weight loss and survival after infection with Influenza A virus.

C57BL/6J, DBA/2J, FVB/NJ, CBA/J, BALB/cByJ, A/J and SJL/JOrlCrl mice were infected intra-nasally with 2×10³ FFU of PR8 virus. Weight loss and survival of infected mice was followed over a period of 14 days. Mortality also includes mice that were sacrificed because they had lost more than 25% of body weight. Mean percent of body weight change (±SEM) for each group of inbred strains is shown. For DBA/2J and C57BL/6J mice, data are from two independent experiments. Statistical analysis of pair wise comparisons for all strains and days are presented in table 1.
