To assess the persistence of nosocomial vegetative bacteria and spores on surfaces and evaluate their inactivation by hydrogen peroxide vapor in a room setting.
Inocula of 6 to 7 log10 CFU of vegetative bacteria and bacterial spores were applied to surfaces to monitor environmental survival.
Inactivation efficacy was tested in a 100-m³ room exposed to hydrogen peroxide vapor, incorporating 0.3% bovine serum albumin to simulate biological soiling.
Most vegetative bacteria and spores survived on test surfaces for longer than 5 weeks.
Hydrogen peroxide vapor achieved complete inactivation of all tested bacteria and spores within 90 minutes, even in the presence of 0.3% bovine serum albumin.
