a
Results are expressed as the population mean log10 CFU (gram wet weight of feces)−1 ± standard error of the mean for each group. NA, not applicable; NF, not found. Samples were taken from 12 HY, 6 HE, and 10 AE.
b
Results show the range log10 CFU (gram wet weight of feces)−1 of subjects in which the bacteria were isolated.
c
Values in parentheses are the number of subjects positive for carriage of the bacteria.
