Trial Outcomes & Findings for Analysis of the Effect of Antimicrobial Soap on Bacterial Survival (NCT NCT02012348)

NCT ID: NCT02012348

Last Updated: 2019-10-03

Results Overview

A skin swab will be used to measure the bacterial survival 30 minutes after bacteria application and soap treatment. The bacteria being applied and subsequently measured is Group A Streptococcus (GAS). The bacterial survival is expressed as abundance of GAS relative to abundance of other bacterial species isolated from the swab.

The bacteria being applied and subsequently measured is Group A Streptococcus (GAS). The bacterial survival is expressed as abundance of GAS relative to abundance of other bacterial species isolated from the swab.

SECONDARY outcome

Timeframe: 1 hour after bacteria application / 2 hours post washing

A skin swab will be used to measure the bacterial survival 1 hour after bacteria application (2 hours post washing with soap). The bacteria being applied and subsequently measured is Group A Streptococcus (GAS). The bacterial survival is expressed as abundance of GAS relative to abundance of other bacterial species isolated from the swab.
