Humans' noses may have hidden crevices where the bacteria that cause staph infections like to hang out.
Scientists knew that the nose was a primary reservoir of Staphylococcus aureus. But a deeper look within the nasal cavity revealed previously unidentified spots that harbored the potentially dangerous bacteria. The discovery could explain why some people only get rid of staph microbes for a short amount of time when treated, researchers report December 11 in Cell Host & Microbe.
The team also found that when more of the bacteria Corynebacterium pseudodiphtheriticum was present in the nose, there were fewer S. aureus microbes. C. pseudodiphtheriticum may make a molecule that blocks the growth of S. aureus and, if identified, could lead to the development of a new drug to treat or prevent staph infections.
