The Gram-negative diplococcus Neisseria meningitidis, the meningococcus, remains a globally important causative agent of meningitis and septicaemia (severe sepsis). Ten Years ago, the Meningitis Research Foundation funded the establishment of the UK ‘Meningitis Research Foundation Meningococcus Genome Library’ (MRF-MGL). Embedded within the PubMLST.org platform. Shortly after its inception, the MRF-MGL contributed to the introduction of the ACYW meningococcal vaccines into the UK and it remains an essential resource, nationally and internationally.
