Meningococcus, this famous unknown

Abstract

Neisseria meningitidis (meningococcus) is a Gram-negative bacterium responsible for two devastating forms of invasive diseases: purpura fulminans and meningitis. Since the first description of the epidemic nature of the illness at the dawn of the nineteenth century, the scientific knowledge of meningococcal infection has increased greatly. Major advances have been made in the management of the disease with the advent of antimicrobial therapy and the implementation of meningococcal vaccines. More recently, an extensive knowledge has been accumulated on meningococcal interaction with its human host, revealing key processes involved in disease progression and new promising therapeutic approaches.
