a

The IC, i.e., the slope of the semilogarithmic survival curves (see Materials and Methods), was determined for each strain and each treatment.

b

Data are averages and standard deviations (n = 4). Asterisks indicate IC values that were significantly different from the respective wild-type IC (P ≤ 0.05).
