The search for a vaccine against group B streptococci Group B streptococci are one of the leading causes of infection in newborn infants, causing pneumonia, septicaemia or meningitis. A group of Portuguese researchers and a team in a CNRS-associated laboratory at the Institut Pasteur have just identified a protein in this micro-organism which allows it to colonise a host by modulating its immune system. According to these scientists, who have published this study in the Journal of Immunology, the protein thus identified is a possible candidate for the development of a vaccine against Group B Streptococci. >>> Discuss This Story
