Cold-Air Atmospheric Pressure Plasma Against Clostridium difficile Spores: A Potential Alternative for the Decontamination of Hospital Inanimate Surfaces

Clostridium difficile spores survive for months on environmental surfaces and are highly resistant to decontamination. We evaluated the effect of cold-air plasma against C. difficile spores. The single-jet had no effect while the multi-jet achieved 2-3 log10 reductions in spore counts and may augment traditional decontamination.
