Genetic Meningococcal Antigen Typing System (gMATS): A genotyping tool that pre...
Muzzi, Alessandro; Brozzi, Alessandro; Serino, Laura; Bodini, Margherita; Abad, Raquel; Caugant, Dominique; Comanducci, Maurizio; Lemos, Ana PaulaBackground: The Meningococcal Antigen Typing System (MATS) was developed to identify meningococcus group B strains with a high likelihood of being covered by the 4CMenB vaccine, but is limited by the requirement for viable isolates from culture-confirmed cases. We examined if antigen genotyping could complement MATS in predicting strain coverage by the 4CMenB vaccine. Methods: From a panel of 3912 MATS-typed in...
Increase of invasive meningococcal serogroup W disease in Europe, 2013 to 2017
Krone, Manuel; Gray, Steve; Abad, Raquel; Skoczyńska, Anna; Stefanelli, Paola; van der Ende, Arie; Tzanakaki, Georgina; Mölling, PaulaBackground: The total incidence of invasive meningococcal disease (IMD) in Europe has been declining in recent years; however, a rising incidence due to serogroup W (MenW), predominantly sequence type 11 (ST-11), clonal complex 11 (cc11), was reported in some European countries. Aim: The aim of this study was to compile the most recent laboratory surveillance data on MenW IMD from several European countries to ...
Meningococcal serogroup Y disease in Europe: Continuation of high importance in...
Bröker, Michael; Emonet, Stéphane; Fazio, Cecilia; Jacobsson, Susanne; Koliou, Maria; Kuusi, Markku; Pace, David; Paragi, Metka; Pysik, AlexanderNeisseria meningitidis or meningococcus is divided into 12 distinct serogroups of which A, B, C, W, X, and Y are medically most important and cause health problems in different parts of the world. The epidemiology of N. meningitidis is unpredictable over time and across geographic regions. Globally, serogoup A has been prevalent in the African “meningitis belt” whereas serogroup B and C have predominated in Eur...
Implications of differential age distribution of disease-associated meningococc...
Brehony, Carina; Trotter, Caroline L.; Ramsay, Mary E.; Jolley, Keith A.; van der Ende, Arie; Carion, Françoise; Berthelsen, Lene; Hoffmann, SteenNew vaccines targeting meningococci expressing serogroup B polysaccharide have been developed, with some being licensed in Europe. Coverage depends on the distribution of disease-associated genotypes, which may vary by age. It is well established that a small number of hyperinvasive lineages account for most disease, and these lineages are associated with particular antigens, including vaccine candidates. A col...
