Ear infection mix
What’s living in children’s noses could determine whether they get ear infections. Researchers from Yale and the University of Pennsylvania took swabs from the noses of sick children with and without ear infections. Kids with ear infections were more likely to carry Streptococcus pneumoniae bacteria, a major cause of pneumonia and ear infections. Some other types of bacteria seemed to protect against both Streptococcus and ear infections, the researchers reported online February 1 in mBio. Yet other types of bacteria promoted ear infection, including types that don’t cause ear infections themselves. The findings could lead to new ways to prevent ear infections. —Tina Hesman Saey
