PRIMARY outcome

Timeframe: 10 minutes and 6 hours after application of test solutions

Population: Measure Analysis Population Description: Number analyzed is not equal to participants treated but rather equal to the number of treated sites for individuals who met the baseline bacterial load criteria on treatment day

The bacterial reductions achieved by the test products and the controls using 2 different application techniques at 10-minute and 6-hour sampling intervals for both groin and abdominal sites were evaluated.
