An EU-funded team of researchers has identified a new array of genes that may be responsible for infections caused by pathogenic microorganisms, such as Group A Streptococcus, which causes thousands of deaths every year. The study, carried out as part of the EUR 3 million project PathoGenoMics, funded under the Sixth Framework Programme (FP6), will help scientists gain a better understanding of how bacterial-host interactions cause streptococcal infections. The results are published in the journal PLoS (Public Library of Science) Pathogens.
