This study aimed to evaluate the knowledge and attitudes about Meningococcal meningitis B and the relative vaccine for children among a sample of parents in Italy. A cross-sectional investigation was conducted from October to December 2015 among a sample of 910 parents in the geographic area of Naples and Salerno (Italy). In total, 543 of 910 parents returned a completed questionnaire for a response rate of 59.7%. Almost all parents had heard about meningitis (95.8%), 79.8% of these knew the mode of transmission (through respiratory droplets) and 62...

The phrase "Process is the Product" is often applied to biologics, including multicomponent vaccines composed of complex components that evade complete characterization. Vaccine production processes must be defined and locked early in the development cycle to ensure consistent quality of the vaccine throughout scale-up, clinical studies, and commercialization. This approach of front-loading the development work helped facilitate the accelerated approval of the Biologic License Application for the well-characterized vaccine bivalent rLP2086 (Trumenba®, Pfizer Inc) in 2014 under Breakthrough Therapy Designation...

BACKGROUND: Several concepts are available to explain vaccine decision making by individual and inter-individual factors, including risk perception, social conformism and altruism. However, only a few studies have quantified the weight of these determinants in vaccine acceptance. Using a conjoint analysis tool, we aimed at eliciting preferences in a student population regarding vaccination against a rare, severe and rapidly evolving hypothetical disease, similar to meningococcal serogroup C meningitis or measles...

We describe a rare case of infantile meningococcal (serotype B) meningitis in a 3-month-old Chinese boy with an atypical indolent presentation with prolonged persistent fever despite appropriate antimicrobial therapy likely due to drug fever. The case highlights the need for continued vigilance in identifying similar cases in the future.

Neisseria meningitidis (Nm) and Neisseria lactamica (Nl) are commensal bacteria that live in the human nasopharynx, where they form microcolonies. In contrast to Nl, Nm occasionally causes blood and/or meningitis infection with often fatal consequences. Here, we studied interactions between neisserial strains during biofilm formation. Fluorescent strains were engineered and analyzed for growth in single- and dual-strain biofilms with confocal laser-scanning microscopy. Different strains of diverse Neisseria species formed microcolonies of different sizes and morphologies...

Complement C5 deficiency (C5D) is a rare primary immunodeficiency associated with recurrent infections, particularly meningitis, by Neisseria species. To date, studies to elucidate the molecular basis of hereditary C5D have included fewer than 40 families, and most C5 mutations (13 of 17) have been found in single families. However, the recently described C5 p.A252T mutation is reported to be associated with approximately 7% of meningococcal disease cases in South Africa. This finding raises the question of whether the mutation may be prevalent in other parts of Africa or other continental regions...

Meningococcal disease is rare, easily misdiagnosed, and potentially deadly. Diagnosis in the early stages is difficult and the disease often progresses extremely rapidly. In North America, the incidence of invasive meningococcal disease (IMD) is highest in infants and young children, with a secondary peak in adolescents, a population predominantly responsible for the carriage of disease. Neisseria meningitidis serogroup B (MenB) accounts for a large proportion of meningococcal disease in North America, with documented outbreaks in three universities in the United States (US) during 2008-2013...

Neisseria meningitidis is a human commensal that can also cause life-threatening meningitis and septicemia. Despite growing evidence for RNA-based regulation in meningococci, their transcriptome structure and output of regulatory small RNAs (sRNAs) are incompletely understood. Using dRNA-seq, we have mapped at single-nucleotide resolution the primary transcriptome of N. meningitidis strain 8013. Annotation of 1625 transcriptional start sites defines transcription units for most protein-coding genes but also reveals a paucity of classical σ70-type promoters, suggesting the existence of activators that compensate for the lack of -35 consensus sequences in N...

Primary meningococcal meningitis is an infrequent but known disease. However, the infection of a prosthetic joint with Neisseria meningitidis is rare. We hereby describe the second case of an arthroplasty infected with Neisseria meningitidis that responded favourably to prosthesis retention with surgical debridement, in combination with antibiotics treatment.

Neisseria meningitidis causes meningococcal disease often resulting in fulminant meningitis, sepsis and death. Vaccination programmes have been developed to prevent infection of this pathogen but serogroup replacement is a problem. Capsular switching has been an important survival mechanism for N. meningitidis allowing the organism to evolve in the present vaccine era. However, related mechanisms have not been completely elucidated. Genetic analysis of capsular switching between diverse serogroups would help further our understanding of this pathogen...

BACKGROUND: Routine infant immunization with meningococcal C conjugate (MCC) vaccination started in Brazil in November 2010, scheduled at three and five months plus a booster at 12-15months of age. No catch-up was implemented. We assessed the impact of vaccination on meningococcal C disease (MenC) four years after vaccination start in the National Immunization Program. METHODS: We performed an ecological quasi-experimental design from 2008 to 2014 using a deterministic linkage between the National Notification and the National Reference Laboratory databases for meningitis...

BACKGROUND: Invasive meningococcal disease (IMD) is a major cause of bacterial meningitis and septicaemia although infection by some serogroups may be prevented through vaccination. We aimed to describe the epidemiology of IMD in EU/EEA countries during 2004-2014 to monitor serogroup- and age-specific trends, and compare country trends by the period of meningococcal C conjugate (MCC) vaccine introduction. METHODS: We analysed IMD surveillance data by age, gender, serogroup, country and outcome...

BACKGROUND: Vibrio cholerae, a Gram-negative, non-spore forming curved rod is found in diverse aquatic ecosystems around the planet. It is classified according to its major surface antigen into around 206 serogroups, of which O1 and O139 cause epidemic cholera. A recent spatial modelling technique estimated that around 2.86 million cholera cases occur globally every year, and of them approximately 95,000 die. About 1.3 billion people are currently at risk of infection from cholera. Meta-analysis and mathematical modelling have demonstrated that due to global warming the burden of vector-borne diseases like malaria, leishmaniasis, meningococcal meningitis, viral encephalitis, dengue and chikungunya will increase in the coming years in the tropics and beyond...

BACKGROUND: The meningococcal capsule is an important virulence determinant. Unencapsulated meningococci lacking capsule biosynthesis genes and containing the capsule null locus (cnl) are predominantly non-pathogenic. Rare cases of invasive meningococcal disease caused by cnl isolates belonging to sequence types (ST) and clonal complexes (cc) ST-845 (cc845), ST-198 (cc198), ST-192 (cc192) and ST-53 (cc53) have been documented. The clinical significance of these isolates however remains unclear...

Meningococcal infection is an important public health concern. Neisseria meningitidis usually colonizes the nasopharynx of healthy adolescents and adults and remains as asymptomatic colonizer, while in rare cases it may present as invasive disease as either meningitis or septicemia or both. Most of the cases have typical presentation of rashes. We hereby present a case of a 40-year-old male who presented with meningococcal meningitis and peripheral digital gangrene but without development of typical rashes...

BACKGROUND-: Meningococcal C glycoconjugate vaccine (MenCV) has been recommended in France since 2010, but its uptake remains low (64% coverage among two-year-olds in 2014). Because general practitioners (GPs) are the cornerstone of the French vaccination program, we sought to assess their perceptions, attitudes, practices and recommendations to patients for this vaccine. METHODS-: A cross-sectional survey in 2014 asked a national sample of 1582 GPs if they would recommend MenCV for patients 12 months of age (routine vaccination) and 2-24 years of age (catch-up vaccination), and explored barriers to vaccination...

BACKGROUND: Neisseria meningitidis is a globally important cause of meningitis and septicaemia. Twelve capsular groups of meningococci are known, and quadrivalent vaccines against four of these (A, C, W and Y) are available as plain-polysaccharide and protein-polysaccharide conjugate vaccines. Here we apply contemporary methods to describe B-cell responses to meningococcal polysaccharide and conjugate vaccines. METHODS: Twenty adults were randomly assigned to receive either a meningococcal plain-polysaccharide or conjugate vaccine; one month later all received the conjugate vaccine...

Hyperinvasive lineages of Neisseria meningitidis, which persist despite extensive horizontal genetic exchange, are a major cause of meningitis and septicaemia worldwide. Over the past 50 years one such lineage of meningococci, known as serogroup A, clonal complex 5 (A:cc5), has caused three successive pandemics, including epidemics in sub-Saharan Africa. Although the principal antigens that invoke effective immunity have remained unchanged, distinct A:cc5 epidemic clones have nevertheless emerged. An analysis of whole genome sequence diversity among 153 A:cc5 isolates identified eleven genetic introgression events in the emergence of the epidemic clones, which primarily involved variants of core genes encoding metabolic processes...

A new MenACWY conjugate meningococcal vaccination programme was introduced in Northern Ireland (NI) in August 2015, for 13-18 year olds, as well as for first-time university entrants up to 25 years. This reflected the response made by Public Health England, due to the recent rapid increase of meningococcal group W (MenW) disease and on advice of the UK Joint Committee on Vaccination and Immunisation (JCVI). The aims of this study were to evaluate (i) the uptake of the MenACWY vaccine among first-time university students, (ii) vaccine and meningitis awareness, (iii) optimal communication modalities via a multidisciplinary team (MDT) model and (iv) current international vaccination policies relating to non-UK students...

Some members of the physiological human microbiome occasionally cause life-threatening disease even in immunocompetent individuals. A prime example of such a commensal pathogen is Neisseria meningitidis, which normally resides in the human nasopharynx but is also a leading cause of sepsis and epidemic meningitis. Using N. meningitidis as model organism, we tested the hypothesis that virulence of commensal pathogens is a consequence of within host evolution and selection of invasive variants due to mutations at contingency genes, a mechanism called phase variation...
