Discovery of a new, previously unknown mechanism of immunity suggests that there may be a better way to protect vulnerable children and adults against Streptococcus pneumoniae (pneumococcal) infection, say researchers at Children's Hospital Boston and Harvard School of Public Health (HSPH).

Research led by the University of Warwick has uncovered exactly how the bacterium Streptococcus pneumoniae has become resistant to the antibiotic penicillin. The same research could also open up MRSA to attack by penicillin and help create a library of designer antibiotics to use against a range of other dangerous bacteria.

A strain of the bacteria Streptococcus pneumoniae, which can cause ear infections in children, has been detected that is resistant to all FDA-approved antibiotics for treatment of ear infections and is not covered by the pneumococcal 7-valent conjugate vaccine, according to a study in the October 17 issue of JAMA.

Researchers believe they have discovered why a bacterial lung infection is so lethal in the early stages, and it’s not what medical authorities had thought, according to research published August 23 in the journal Immunity.

When the space shuttle Endeavour touched down at the Kennedy Space Center August 21, University of Texas Medical Branch at Galveston microbiology and immunology department chairman David Niesel was waiting by the runway, looking forward to a reunion with some of its passengers.

For parents, 8 million cases of acute middle ear infections every year add up to a lot of sleepless nights and trips to the pediatrician. But new research from a collaboration between Rockefeller University and St. Jude Children's Hospital could change all that.
