Figure 2. Weight loss of mice infected with wild-type (WT) or H274Y mutant isolates of pH1N1.

The weight loss of mice was evaluated in two groups of 15 mice (infected with the WT and H274Y mutant isolate) over a period of 14 days. These experiments were performed twice and reported as #1 and #2 on the graph. * P<0.05 between the WT and H274Y pH1N1 weight losses.
