  • a Counts were obtained for immunogold-localized bacteria present in the infected gut tissue. Eight 3-mm transverse lengths of cecum were analyzed for each independent infection, and the standard deviations of the means of the counts are indicated in parentheses. There are no significant differences between the two data sets.
