According to research published in mBio, scientists have demonstrated that a harmless bacterium found in the nose and on skin may negatively impact the growth of a pathogen that commonly causes middle ear infections in children and pneumonia in children and older adults.
This study provides the first evidence that Corynebacterium accolens, a harmless bacterial species that commonly colonizes the nose, can help inhibit Streptococcus pneumoniae (S. pneumoniae) — a major cause of pneumonia, meningitis, middle ear infection and sinusitis.
According to the World Health Organization, S. pneumoniae leads to more than 1 million deaths each year, primarily in young children in developing countries. Although most people that host S. pneumoniae do not develop these infections, colonization greatly increases the risk of, and is a perquisite for, infection and transmission.
