Data are averages of three independent replications for each treatment. Five filters per dilution were used in each treatment. For each assay date, different symbols indicate a significant difference (Student's t test, P < 0.05) between the wild-type and mutant survival rates. The data for days 10 to 14 were all 0 and are not shown.
