BACKGROUND: Recently the incidence of meningococcal serogroup Y (MenY) and in particular serogroup W (MenW) invasive disease has risen in several European countries, including the Netherlands. Adolescents are a target group for primary prevention through vaccination to protect against disease and reduce carriage and induce herd protection in the population. The present study assessed MenA, MenW and MenY antibody levels in adolescents up to one year following primary vaccination with quadrivalent MenACWY-PS conjugated to tetanus toxoid (MenACWY-TT)...

The tetanus neurotoxin (TeNT) is a highly potent toxin produced by Clostridium tetani that inhibits neurotransmission of inhibitory interneurons, causing spastic paralysis in the tetanus disease. TeNT differs from the other clostridial neurotoxins by its unique ability to target the central nervous system by retrograde axonal transport. The crystal structure of the tetanus toxin reveals a "closed" domain arrangement stabilised by two disulphide bridges, and the molecular details of the toxin's interaction with its polysaccharide receptor...

Tetanus is declining due to vaccination, professional labor management and appropriate wound care. Tetanus cases have been reported despite immunization. We report the case of a previously healthy 21 years old female patient that presented a mild generalized tetanus requiring admission after mild and recurrent cat scratch and bites. She had received six vaccine shots during childhood, and a booster dose five years earlier after a rabbit bite. Symptoms appeared seven weeks after the last contact, and included headache, muscle spasms and mild opisthotonus...

d-Arabinose-5-phosphate isomerases (APIs) catalyze the interconversion of d-ribulose-5-phosphate and d-arabinose-5-phosphate. Various Gram-negative bacteria, such as the uropathogenic E. coli strain CFT073, contain multiple API paralogs (KdsD, GutQ, KpsF and c3406) that have been assigned various cellular functions. The d-arabinose-5-phosphate formed by these enzymes seems to play important roles in the biosynthesis of lipopolysaccharide and group 2 K-antigen capsules, as well as in the regulation of the cellular d-glucitol uptake and uropathogenic infectivity/virulence...

Anecdotal case reports, amplified by mass media and internet-based opinion groups, have recently indicated vaccinations as possibly responsible for autoimmunity/lymphoproliferation development. Multiply vaccinated Italian military personnel (group 1, operating in Italy, group 2, operating in Lebanon) were followed-up for nine months to monitor possible post-vaccine autoimmunity/lymphoproliferation onset. No serious adverse event was noticed in both groups. Multivariate analysis of intergroup differences only showed a significant association between lymphocyte increase and tetanus/diphtheria vaccine administration...

Nanoliposomes (NLs) hold promise as new highly specific nanomedicine for anti-tumor vaccines, since they could be targeted to specific receptors on dendritic cell (DC) to induce maturation and activation and increase the anti-tumor immune response. Here we studied a NLs formulation targeted or not to FcR (the receptor for the IgG Fc fragment) for the treatment of androgen-responsive prostate cancer. Luteinizing-hormone-releasing hormone (LHRH) peptide (B- and T-cell epitopes), in tandem with a tetanus toxoid T-helper epitope (830-844 region) and several TLR (Toll-Like Receptor) ligands as adjuvants were co-encapsulated...

BACKGROUND: Although global neonatal mortality declined by about 40 percent from 1990 to 2013, it still accounted for about 2.6 million deaths globally and constituted 42 percent of global under-five deaths. Most of these deaths occur in developing countries. Antenatal care (ANC) is a globally recommended strategy used to prevent neonatal deaths. In Kenya, over 90 percent of pregnant women attend at least one ANC visit during pregnancy. However, Kenya is currently among the 10 countries that contribute the most neonatal deaths globally...

Chronic prostatitis (CP) with complex pathogenesis is difficult for treatment. c-kit has been associated with the control of cell proliferation of prostate cells. This study aims to evaluate the role of resveratrol, an activator of Sirt1, in regulating the expression of c-kit in CP and investigate the consequent effects on cell cycle. Rat model of CP was established through subcutaneous injections of diphtheria-pertussis-tetanus vaccine and subsequently treated with resveratrol. Hematoxylin and eosin staining was performed to identify the histopathological changes in prostates...

PURPOSE: Despite the long history of pertussis vaccination and high vaccination coverage in Poland and many other developed countries, pertussis incidence rates have increased substantially, making whooping cough one of the most prevalent vaccine-preventable diseases. Among the factors potentially involved in pertussis resurgence, the adaptation of the Bordetella pertussis population to country-specific vaccine-induced immunity through selection of non-vaccine-type strains still needs detailed studies...

INTRODUCTION: Adverse events following immunization (AEFI) may follow the use of any vaccine. There is thus a need for documentation of the types and prevalence of AEFIs for each vaccine and early identification of new events or those occurring at rates higher than expected. When one vaccine replaces another, it is important to document the safety of the new vaccine as well as compare to that of the old. In this study, we aimed to document the AEFIs following the use of pentavalent vaccine recently introduced into the National Programme on Immunization and compare with those of diphtheria-tetanus-pertussis (DTwP) vaccine which it replaced...
