Survival of nosocomial bacteria and spores on surfaces and inactivation by hydrogen peroxide vapor

J Clin Microbiol. 2009 Jan;47(1):205-7. doi: 10.1128/JCM.02004-08. Epub 2008 Oct 29.

Abstract

With inocula of 6 to 7 log(10) CFU, most vegetative bacteria and spores tested survived on surfaces for more than 5 weeks, but all were inactivated within 90 min of exposure to hydrogen peroxide vapor in a 100-m(3) test room even in the presence of 0.3% bovine serum albumin to simulate biological soiling.
