In the period 2008-2010, 309 Neisseria meningitidis, isolated in Italy within the National Surveillance of the Invasive Meningococcal Diseases, have been tested for their phenotypic and genotypic characteristics. The main results obtained are: (a) an increase of the strains of serogroup B and a decrease of serogroup C; (b) a phenotypic and genotypic variability of the ST-41/44 clonal complex, t...
background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...
siaD PCR ELISA for confirmation and identification of serogroup Y and W135 meningococcal infections.
Non-culture diagnosis and serogroup determination of meningococcal infection is important in contact management where vaccination may be possible. A serogroup B and C PCR ELISA assay for the non-culture diagnosis and serogroup determination has proved invaluable for enhanced epidemiological surveillance and contact management. A polymerase chain reaction assay, based on a restriction fragment l...
The National Neisseria Network has undertaken meningococcal isolate surveillance by means of a collaborative laboratory-based initiative since 1994. The phenotype (serogroup, serotype and serosubtype) and antibiotic susceptibility of 323 isolates of Neisseria meningitidis from invasive cases of meningococcal disease were determined in 1998. Ninety per cent of the invasive isolates were either s...

Chlamydia trachomatis serovars are divided into three serogroups, namely serogroup B, serogroup I (Intermediate) and serogroup C, and subsequently into 19 different serovars. Worldwide, serogroup B is the most prevalent followed by serogroup I. Clear differences have been observed in the duration of infection and growth kinetics between serovars from different serogroups in murine and cell cult...
BACKGROUND In 2013-2014, an outbreak of serogroup B meningococcal disease occurred among persons linked to a New Jersey university (University A). In the absence of a licensed serogroup B meningococcal (MenB) vaccine in the United States, the Food and Drug Administration authorized use of an investigational MenB vaccine to control the outbreak. An investigation of the outbreak and response was ...
This policy statement provides recommendations for the prevention of serogroup B meningococcal disease through the use of 2 newly licensed serogroup B meningococcal vaccines: MenB-FHbp (Trumenba; Wyeth Pharmaceuticals, a subsidiary of Pfizer, Philadelphia, PA) and MenB-4C (Bexsero; Novartis Vaccines, Siena, Italy). Both vaccines are approved for use in persons 10 through 25 years of age. MenB-F...
In 2007 there were 281 laboratory-confirmed cases of invasive meningococcal disease analysed by the National Neisseria Network, a nationwide network of reference laboratories. The phenotypes (serogroup, serotype and serosubtype) and antibiotic susceptibility of 154 isolates of Neisseria meningitidis from invasive cases of meningococcal disease were determined and an additional 127 cases were co...
Neisseria meningitidis serogroups A, B, C, W, X, and Y cause outbreaks of meningococcal disease. Quadrivalent conjugate vaccines targeting the are available. A pentavalent vaccine that also includes serogroup X (NmCV-5) is under development.
