Table 2: Tissue (CFU/g) Log reduction summary tables for day 21. Log reduction values higher than 4 are bold and underlined.
(a) For pairwise comparison, the mean Log10 CFU/g recovered from the three replicates of test articles/rabbit was subtracted from the mean Log10 CFU/g recovered from the three replicates of control articles/rabbit per segment
