Characterization of meningococcal carriage isolates from Greece by whole genome sequencing: Implications for 4CMenB vaccine implementation.

PLoS One 2018 28;13(12):e0209919. Epub 2018 Dec 28.

National Meningitis Reference Laboratory (NMRL), Dept of Public Health, National School of Public Health, Athens, Greece.

Herd protection, resulting from the interruption of transmission and asymptomatic carriage, is an important element of the effectiveness of vaccines against the meningococcus. Whilst this has been well established for conjugate polysaccharide vaccines directed against the meningococcal capsule, two uncertainties surround the potential herd protection provided by the novel protein-based vaccines that are used in place of serogroup B (MenB) polysaccharide vaccines (i) the strain coverage of such vaccines against carried meningococci, which are highly diverse; and (ii) the generation of a protective immune response in the mucosa. These considerations are essential for realistic estimates of cost-effectiveness of new MenB vaccines. Read More

The Meningococcal Cysteine Transport System Plays a Crucial Role in Survival in Human Brain Microvascular Endothelial Cells.

MBio 2018 12 11;9(6). Epub 2018 Dec 11.

RIKEN Structural Biology Laboratory, Yokohama, Japan.

While typically exists in an asymptomatic nasopharyngeal carriage state, it may cause potentially lethal diseases in humans, such as septicemia or meningitis, by invading deeper sites in the body. Since the nutrient compositions of human cells are not always conducive to meningococci, needs to exploit nutrients from host environments. In the present study, the utilization of cysteine by the meningococcal cysteine transport system (CTS) was analyzed for the pathogenesis of meningococcal infections. Read More

Differential influences of complement on neutrophil responses to Neisseria meningitidis infection.

Pathog Dis 2018 Nov 1;76(8). Epub 2018 Nov 1.

Institute for Hygiene and Microbiology, University of Würzburg, 97080 Würzburg, Germany.

The complement system is the primary innate immune determinant protecting against invasive diseases caused by the Gram-negative bacterium Neisseria meningitidis (Nme, meningococcus), as evidenced by the extreme susceptibility of individuals with complement deficiencies. In contrast, the role of phagocytes such as neutrophils is much less well understood, although they are recruited in great numbers to the cerebrospinal fluid during meningococcal meningitis. Here, we consider the interaction of Nme with primary human neutrophils using either purified cells or a whole blood model of infection. Read More

Invasive Meningococcal Disease in the Vaccine Era.

Front Pediatr 2018 9;6:321. Epub 2018 Nov 9.

Paediatrics, St Mary's Hospital, London, United Kingdom.

Infection with the meningococcus is one of the main causes of meningitis and septicaemia worldwide. Humans are the only natural reservoir for the meningococcus which is found primarily as a commensal inhabitant in the nasopharynx in ~10% of adults, and may be found in over 25% of individuals during adolescence. Prompt recognition of meningococcal infection and early aggressive treatment are essential in order to reduce mortality, which occurs in up to 10% of those with invasive meningococcal disease (IMD).
