Elucidating the pathogenic mechanism of meningococcal meningitis

Neisseria meningitidis, also called meningococcus, is a bacterium responsible for meningitis and septicemia1. Its most serious form, purpura fulminans, is often fatal. This bacterium, which is naturally present in humans in the nasopharynx, is pathogenic if it reaches the blood stream. Teams led by Dr. Sandrine Bourdoulous, CNRS senior researcher at the Institut Cochin (CNRS/INSERM/Université Paris Descartes), and Professor Xavier Nassif, Institut Necker Enfants Malades (CNRS/INSERM/Université Paris Descartes/Assistance Publique - Hôpitaux de Paris), have deciphered the molecular events through which meningococci target blood vessels and colonize them. This work opens a path to new therapeutic perspectives for treating vascular problems caused by this type of invasive infection. The study was published on June 1, 2014 in Nature Medicine.
