which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Editorial Meningococcal disease presenting with meningitis or sepsis is a life-threatening illness with significant morbidity and mortality worldwide. Despite providing appropriate antibiotic therapy and supportive care, invasive meningococcal disease could ...
Listeria monocytogenes isolates recovered from retail ready-to-eat (RTE) meats, raw chickens and fresh produce were characterized by serogroup identification using PCR, genotyping using pulsed-field gel electrophoresis (PFGE) and antimicrobial susceptibility testing. Five L. monocytogenes serogroups were identified. Of the 167 isolates 68 (41%) belonged to serogroup 1/2b, 3b; 53 (32%) belonged ...
BACKGROUND Several countries consider the implementation of a meningococcal serogroup B vaccine for young children and/or serogroup C or ACWY conjugate vaccine for adolescents. Representative information on clinical course of invasive meningococcal disease (IMD) is useful to evaluate cost-effectiveness of vaccination. Information on the relation between infecting meningococcal clonal complex (C...
This study was performed to determine the incidence and serogroups of meningococcal disease in the Korean Army. From August 2000 to July 2001, we identified prospective cases in the Korean Army. Meningococcal disease was confirmed by isolation of Neisseria meningitidis or detection of its antigen by latex agglutination from cerebrospinal fluid (CSF) or blood. Polymerase chain reactions (PCRs) w...
Serum immunoglobulin G (IgG) and IgM were measured for individual Salmonella species by the enzyme-linked immunosorbent assay (ELISA). F344 rats were experimentally infected with Salmonella typhimurium (serogroup B), S. enteritidis (serogroup D), and S. rubislaw (serogroup G.) Endotoxin extracted from each serogroup served as the antigen in a classical indirect ELISA. Antibody specific for each...
BACKGROUND A quadrivalent meningococcal conjugate vaccine (MCV4) was licensed in the United States in 2005; no serogroup B vaccine is available. Neisseria meningitidis changes its capsular phenotype through capsular switching, which has implications for vaccines that do not protect against all serogroups. METHODS Meningococcal isolates from 10 Active Bacterial Core surveillance sites from 200...
INTRODUCTION Neisseria meningitidis serogroup B is an important infectious agent in developed countries, including Canada. Infants are particularly susceptible to infection with serogroup B because of immature immune systems, pathogen virulence factors and changing serogroup dynamics in the post-vaccination era. Currently, the Ontario provincial government does not include serogroup B in its ro...
BACKGROUND In 1999, meningococcal serogroup C conjugate (MCC) vaccines were introduced in the United Kingdom for those under 19 years of age. The impact of this intervention on asymptomatic carriage of meningococci was investigated to establish whether serogroup replacement or protection by herd immunity occurred. METHODS Multicenter surveys of carriage were conducted during vaccine introduct...
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...
