A re-examination of decontamination protocols to mitigate human-based transmission of Pseudogymnoascus destructans, the causal agent of White Nose Syndrome of bats.

Pseudogymnoascus destructans, the causal agent of White Nose Syndrome, has killed over 6 million bats in eastern North America since the disease was first observed in 2006. One possible mode of pathogen transmission is human-mediated movement among hibernacula (caves and mines) – e.g., on the shoes, clothes and equipment of tourists and the caving community. Protocols to limit transmission have been adopted by government agencies and include: washing submersible materials in specific detergents, then soaking them in hot water (50C) for 20 minutes or in Professional Lysol® Antibacterial All Purpose Cleaner, dilute chlorine bleach or Formula 409® Antibacterial All Purpose Cleaner for 10 minutes. It is recommended that non-submersible materials be wiped down with Lysol® Disinfecting Wipes. Preliminary results using the standard AOAC 955.17 test suggest that the hot water treatment delays spore germination but allows survival of a significant number of spores. Ethanol and isopropanol, at dilutions of 70% and above, seem particularly effective, causing close to 100% spore mortality after exposure of only 20 seconds. Efficacy of other cleaning agents for foot baths and equipment/clothing sanitation will be presented.
