- •Microbial bioburden of the built environment impacts the rate of health care–associated infection acquisition.
- •Two disinfectants registered by the US Environmental Protection Agency were assessed against a first-of-its-kind, persistently active disinfectant to evaluate their ability to limit establishment of bioburden for 24 hours.
- •The persistent agent was found superior in its ability to limit the establishment of bioburden in contrast to the other 2 commonly used hospital disinfectants.
|Median burden observed (CFU/100 cm2)||Is the post disinfection concentration significantly lower than the pre-disinfection concentration (P ≤ .05)?||Is Disinfectant-1 Burden Significantly Lower than Disinfectant-2 or Disinfectant-3 (P ≤ .05)?||% Burden remaining subsequent to disinfection|
