Yellow fever (YF) is a mosquito-borne viral hemorrhagic fever, which is a serious and potentially fatal disease with no specific antiviral treatment that can be effectively prevented by an attenuated vaccine (YEL). Despite the long history of safe and efficacious YF vaccination, sporadic case reports of serious adverse events (SAEs) have been reported, including yellow fever vaccine-associated neurotropic disease (YEL-AND). YEL-AND usually appears within one month of YF vaccination, manifesting as meningoencephalitis, Guillain-Barré syndrome (GBS) or acute disseminated encephalomyelitis (ADEM)...

Meningococci (Neisseria meningiditis) of serogroups A and W have caused large epidemics of meningitis in sub-Saharan Africa for decades, and affordable and multivalent vaccines, effective in all age groups, are needed. A bivalent serogroup A and W (A + W) meningococcal vaccine candidate consisting of deoxycholate-extracted outer membrane vesicles (OMV) from representative African disease isolates was previously found to be highly immunogenic in outbred mice when formulated with the adjuvant aluminium hydroxide (AH)...

Streptococcus pneumoniae (Sp) strain TIGR4 is a virulent, encapsulated serotype that causes bacteremia, otitis media, meningitis and pneumonia. Increased bacterial resistance and limited efficacy of the available vaccine to some serotypes complicate the treatment of diseases associated to this microorganism. Flavodoxins are bacterial proteins involved in several important metabolic pathways. The Sp flavodoxin (Spfld) gene was recently reported to be essential for the establishment of meningitis in a rat model, which makes SpFld a potential drug target...

: Repeating evaluations of vaccine coverage (VC) is essential to measure the implementation and effectiveness of vaccination policy. We report the results of VC in infants from the Vaccinoscopie(®) study in 2014 to assess the changes secondary to the new 2013 immunization schedule. METHOD: Study conducted on Internet among a representative sample of mothers reporting their child's vaccination record. RESULTS: The removal of the dose of DTPa-Hib at the age of 3 months was quickly adopted since only 1 % of children aged 6 months had received three doses of DTPa in 2014 compared to 96 % in 2012...

Tick-borne encephalitis (TBE) is an arbovirus induced by tick-borne encephalitis virus (TBEV) transmitted by tick bite. The disease is rare in France (two to three cases per year) but endemic zones extend from Western Europe to the east coast of Asia (10,000-15,000 cases per year). An 8-year-old boy was admitted to our pediatric ward in Strasbourg (France) for febrile headache with diplopia. Four days after a tick bite, he declared a febrile headache together with maculopapular rash on the elbows, knees, and cheeks...

Streptococcus pneumoniae is an opportunistic pathogen globally associated with significant morbidity and mortality. It is capable of causing a wide range of diseases including sinusitis, conjunctivitis, otitis media, pneumonia, bacteraemia, sepsis, and meningitis. While its capsular polysaccharide is indispensible for invasive disease, and opsonising antibodies against the capsule are the basis for the current vaccines, a long history of biomedical research indicates that other components of this Gram-positive bacterium are also critical for virulence...

BACKGROUND: Haemophilus influenzae type b (Hib) is the leading cause of bacterial meningitis, otitis media, pneumonia, cellulitis, bacteremia, and septic arthritis in infants and young children. The Hib capsule contains the major virulence factor, and is composed of polyribosyl ribitol phosphate (PRP) that can induce immune system response. Vaccines consisting of Hib capsular polysaccharide (PRP) conjugated to a carrier protein are effective in the prevention of the infections. However, due to costly processes in PRP production, these vaccines are too expensive...

Mumps is a highly contagious viral infection that became rare in most industrialized countries following the introduction of measles-mumps-rubella (MMR) vaccine in 1967. The disease, however, has been re-emerging with several outbreaks over the past decade. Many clinicians have never seen a case of mumps. To assist frontline healthcare providers with detecting potential cases and initiating critical actions, investigators modified the "Identify-Isolate-Inform" tool for mumps infection. The tool is applicable to regions with rare incidences or local outbreaks, especially seen in college students, as well as globally in areas where vaccination is less common...

Trumenba (bivalent rLP2086) is a vaccine licensed for the prevention of meningococcal meningitis disease caused by Neisseria meningitidis serogroup B (NmB) in individuals 10-25 years of age in the USA. The vaccine is composed of two factor H binding protein (fHbp) variants that were recombinantly expressed in Escherichia coli as native lipoproteins: rLP2086-A05 and rLP2086-B01. The vaccine was shown to induce potent bactericidal antibodies against a broad range of NmB isolates expressing fHbp that were different in sequence from the fHbp vaccine antigens...

In 2010, the 10-valent pneumococcal conjugate vaccine (PCV10) was introduced to the Brazilian childhood vaccination program. Concerns have been raised that non-vaccine serotypes could increase in prevalence and reduce the benefits of vaccination; therefore, we examined the non-PCV10 isolates recovered from meningitis during pre (January, 2008-May, 2010) and post-vaccine (June, 2010-December, 2012) periods. Surveillance for pneumococcal meningitis was established at the Reference Hospital of Infectious Diseases in Salvador, Brazil...

Extra-intestinal pathogenic Escherichia coli (ExPEC) are responsible for diverse infections including meningitis, sepsis and urinary tract infections. The alarming rise in anti-microbial resistance amongst ExPEC complicates treatment and has highlighted the need for alternative preventive measures. SslE is a lipoprotein secreted by a dedicated type II secretion system in E. coli that was first identified as a potential vaccine candidate using reverse genetics. Although the function and protective efficacy of SslE has been studied, the molecular mechanisms that regulate SslE expression remain to be fully elucidated...

Inclusion of the 10-valent pneumococcal conjugated vaccine (PCV10) in the Chilean infant vaccination Program in 2011 was followed by a reduction of hospital admissions and pneumonia-related deaths in this age group. However, a progressive increase of serotype 19A pneumococcal isolates (not included in PCV10) has been observed. According to the analysis of pneumococcal strains performed by the national reference laboratory of the Institute of Public Health as part of a national surveillance on invasive pneumococcal infections, the relative proportion of serotype 19A isolates increased from <5% before 2010 to 12-23% in years 2014-2015...

BACKGROUND: Several underlying conditions increase the risk of pneumococcal meningitis (PM) in childhood. Patients with these diseases are initially considered as an important target of pneumococcal conjugate vaccines (PCVs). Limited data are available for PM in children with underlying conditions. To understand the benefits of PCV7 followed by PCV13 in this vulnerable population, we analyzed the data for a large cohort of pediatric patients with PM in France from 2001 to 2014. METHODS: We conducted hospital-based active surveillance with 227 pediatric wards working with 168 microbiology departments throughout France...

INTRODUCTION: Pneumonia remains a common reason for hospitalizing infants and the elderly worldwide, and streptococcal infection is often responsible. The aim of this study was to assess the burden of pneumonia in a large general population. METHODS: All pneumonia-related hospitalizations from 2004 to 2013 in north-east Italy were identified from the hospital records with a first-listed diagnosis on discharge of bacterial pneumonia, or a first-listed diagnosis on discharge of meningitis, septicemia or empyema associated with a secondary diagnosis of bacterial pneumonia...

Lipoproteins decorate the surface of many Gram-negative bacterial pathogens, playing essential roles in immune evasion and nutrient acquisition. In Neisseria spp., the causative agents of gonorrhoea and meningococcal meningitis, surface lipoproteins (SLPs) are required for virulence and have been extensively studied as prime candidates for vaccine development. However, the machinery and mechanism that allow for the surface display of SLPs are not known. Here, we describe a transposon (Tn5)-based search for the proteins required to deliver SLPs to the surface of Neisseria meningitidis, revealing a family of proteins that we have named the surface lipoprotein assembly modulator (Slam)...
