Bacterial biofilms are 1,000 times harder to kill than planktonic bacteria. Spores are also harder to kill compared to vegetative cells. We developed a rapid model for establishing dry surface bacterial biofilms for disinfectant efficacy testing and challenged them with seven EPA-registered disinfectants. We also demonstrated that during the disinfection of surfaces contaminated with bacterial spores, disinfectant wipes may transfer spores from contaminated to uncontaminated surfaces.
