New findings detail how beneficial bacteria in the nose suppress pathogenic bacteria

Staphylococcus aureus is a common colonizer of the human body. Although, one quarter of the US population live with the bacteria and never get sick, having S. aureus present in the nostrils is a risk for infections that range in severity from mild skin to life- threatening MRSA infections. Research is providing insight into how harmless Corynebacterium species, bacterial members of the nasal and skin microbiome, help protect humans from disease.
