Effectiveness of saline suspension of Corynebacterium pseudodiphtheriticum containing spray was assessed in a 30-days chamber experiment modeling the effects of hyperthermia and polluted air on humans. Spray was targeted at eliminating Staphylococcus aureus from the nasal cavity of human subjects. Three of four volunteers became S. aureus carriers in the course of the experiment, and one was a chronic carrier of methicillin-resistant S. aureus (MRSA). Spray application eradicated S. aureus in three subjects and reduced its presence in the MRSA carrier. Results of the study suggest that C. pseudodiphtheriticum can be used for control of S. aureus in the nasal environment. However, further investigations are required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
