This paper describes the development of statistical classifiers to help diagnose meningococcal meningitis, i.e. the most sever, infectious and deadliest type of this disease. The goal is to find a mechanism able to determine whether a patient has this type of meningitis from a set of symptoms that can be directly observed in the earliest stages of this pathology. Currently, in Brazil, a country that is heavily affected by meningitis, all suspected cases require immediate hospitalization and the beginning of a treatment with invasive tests and medicines...

BACKGROUND: Serum bactericidal antibody titres that correlate with protection against invasive meningococcal disease have been characterised. However, titres that are associated with protection against acquisition of pharyngeal carriage of Neisseria meningitidis are not known. METHODS: Sera were obtained from the members of a household in seven countries of the African meningitis belt in which a pharyngeal carrier of N. meningitidis had been identified during a cross-sectional survey...

Bacterial meningitis is a severe, acute infection of the fluid surrounding the brain and spinal cord that can rapidly lead to death. Even with recommended antibiotic treatment, up to 25% of infected persons in Africa might experience neurologic sequelae (1). Three regions in northern Ghana (Upper East, Northern, and Upper West), located in the sub-Saharan "meningitis belt" that extends from Senegal to Ethiopia, experienced periodic outbreaks of meningitis before introduction of serogroup A meningococcal conjugate vaccine (MenAfriVac) in 2012 (2,3)...

REVIEW
James Grogan, Karen Roos
PURPOSE OF REVIEW: This review explores the history of serogroup B meningitis outbreaks in American universities and the rise of the monovalent serogroup B meningococcus vaccines (MenB). RECENT FINDINGS: Serogroup B meningitis represents 30% of American meningococcal infections and had no commercially available vaccine in the USA until 2013 when the FDA made an expanded allowance for importation of the MenB-4C vaccine for outbreaks at two American universities. Infections of Neisseria meningitidis, notably meningococcal meningitis represent a continued, lethal threat to the pediatric and adolescent populations and those with primary or acquired complement component deficiencies, largely mitigated by the quadrivalent meningococcal conjugated vaccine against serogroups A, C, W, and Y (MenACWY)...

BACKGROUND: Meningococcal disease usually presents as meningitis and/or septicaemia, but can also present as pneumonia or arthritis. Since 2000, a worldwide increase in meningococcal disease is reported which is caused by a new virulent clone of serogroup W (MenW:cc11). This subtype is more likely to give an atypical clinical presentation and results in high mortality rates. CASE DESCRIPTION: A 68-year-old woman with polymyalgia rheumatica, managed with prednisone, developed an acute gastrointestinal syndrome of nausea, diarrhoea, vomiting, fever and chills...

Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Capsular polysaccharide vaccines are available against meningococcal serogroups A, C, W and Y. More recently two protein based vaccines, Bexsero® and Trumenba®, have been licenced against meningococcal serogroup B strains; both vaccines contain meningococcal factor H binding protein (fHbp). fHbp is a surface exposed lipoprotein which binds the negative complement regulator, complement factor H (CFH), thereby inhibiting the alternative pathway of complement activation...

Neisseria meningitidis is a causative agent of community-acquired sepsis and meningitis in humans. These diseases are associated with high mortality and morbidity if treatment is not started promptly. The empiric antibiotic treatment depends on patient factors and local epidemiology. In the past years, an increased number meningococcal strain with reduced susceptibility to penicillin has also been described. We analysed the susceptibility pattern of 11 N. meningitidis strains isolated between 2013 and 2016...

Neisseria meningitidis is a commensal of human nasopharynx. In some circumstances, this bacteria can invade the bloodstream and, after crossing the blood brain barrier, the meninges. A filamentous phage, designated MDAΦ for Meningococcal Disease Associated, has been associated with invasive disease. In this work we show that the prophage is not associated with a higher virulence during the bloodstream phase of the disease. However, looking at the interaction of N. meningitidis with epithelial cells, a step essential for colonization of the nasopharynx, we demonstrate that the presence of the prophage, via the production of viruses, increases colonization of encapsulated meningococci onto monolayers of epithelial cells...

INTRODUCTION: The use of syndromic surveillance has expanded from its initial purpose of bioterrorism detection. We present 6 use cases from New York City that demonstrate the value of syndromic surveillance for public health response and decision making across a broad range of health outcomes: synthetic cannabinoid drug use, heat-related illness, suspected meningococcal disease, medical needs after severe weather, asthma exacerbation after a building collapse, and Ebola-like illness in travelers returning from West Africa...

OBJECTIVES: To examine clinical characteristics and outcome of patients with late diagnosis of community-acquired bacterial meningitis (CABM). METHODS: We conducted a chart review of all adults with proven CABM in three centres in Denmark from 1998 through 2014. Patients were categorised as 1) early diagnosis of CABM immediately on admission or 2) late diagnosis if CABM was not listed in referral or admission records and neither lumbar puncture nor antibiotic therapy for meningitis was considered immediately on admission...

BACKGROUND: Epidemics of meningococcal meningitis are common in the "African meningitis belt." Current response strategies include reactive vaccination campaigns, which are often organized too late to have maximal impact. A novel strain of Neisseria meningitidis serogroup C has been circulating in recent years, and vaccine supplies are limited. An evaluation of chemoprophylaxis with single-dose ciprofloxacin for household contacts of meningitis cases has therefore been recommended. METHODS/DESIGN: A three-arm cluster-randomized trial has been designed for implementation during a meningococcal meningitis epidemic in a health district in Niger in which at least two Health Zones (HZs) have met the weekly epidemic threshold...

Glycomics is a rapidly growing field that focuses on the structure and function of carbohydrates (glycans) in biological systems. Glycan interactions play a major role in infectious disease, at all stages of colonisation and disease progression. Neisseria meningitidis, the cause of meningococcal sepsis and meningitis, and Neisseria gonorrhoeae, which causes the sexually transmitted infection gonorrhoea, are responsible for significant morbidity and mortality worldwide. N. meningitidis displays a range of surface glycosylations including capsule polysaccharide, lipooligosaccharide and O-linked glycoproteins...

OBJECTIVES: Bacterial meningitis remains an important cause of morbidity and mortality worldwide. Its epidemiological characteristics, however, are changing due to new vaccines and secular trends. Conjugate vaccines against Haemophilus influenzae type b and Streptococcus pneumoniae (10-valent) were introduced in 1986 and 2010 in Finland. We assessed the disease burden and long-term trends of five common causes of bacterial meningitis in a population-based observational study. METHODS: A case was defined as isolation of S...
