Retention of E. coli and water on the skin after liquid contact

Tamar Kohn, Timothy R. Julian

The frequent contact people have with liquids containing pathogenic microorganisms provides opportunities for disease transmission. In this work, we quantified the transfer of bacteria—using E. coli as a model- from liquid to skin, estimated liquid retenti ...
