Background: Despite of the amount of work on the meningococcal serogroup B bacteria and immunity to disease caused by them, a satisfactory vaccine for these important pathogens is still missing. Several group B meningococcal vaccines based on outer membrane protein vesicles (OMV) or complexes have been evaluated in phase II and III clinical trials. Although the antibody responses in connection ...
BACKGROUND Herd immunity is important in the effectiveness of conjugate polysaccharide vaccines against encapsulated bacteria. A large multicenter study investigated the effect of meningococcal serogroup C conjugate vaccine introduction on the meningococcal population. METHODS Carried meningococci in individuals aged 15-19 years attending education establishments were investigated before and ...
Factor 6d antiserum reacts with the new Streptococcus pneumoniae serotype 6C. Serogroup 6 isolates, consisting of 49 6A, 42 6B and 98 6C strains from the United States and Israel, serotyped in parallel by PCR and capsular swelling methods, were all identified correctly. The new factor 6d antiserum accurately identifies serotype 6C.
Sepsis and meningitis caused by Neisseria meningitidis serogroup B (NMGB) are serious diseases in infants and young adults, but no effective vaccine is available. The capsular polysaccharide (PS) of NMGB has poor immunogenicity and a structural similarity to polysialic acid (PSA) on neuronal tissue that may elicit autoantibodies. Using HmenB3, a protective and nonautoreactive monoclonal antibod...
The aim of this study was to characterise and compare Pasteurella multocida isolates originating from pigs (n = 43), calves (n = 31), rabbits (n = 27), and to a lesser extent from other hosts (n = 6). A total of 107 P. multocida isolates were obtained from various locations in the Czech Republic. They were analysed by capsular PCR typing and ribotyping, and tested for the production of dermonec...

In 2007 there were 281 laboratory-confirmed cases of invasive meningococcal disease analysed by the National Neisseria Network, a nationwide network of reference laboratories. The phenotypes (serogroup, serotype and serosubtype) and antibiotic susceptibility of 154 isolates of Neisseria meningitidis from invasive cases of meningococcal disease were determined and an additional 127 cases were co...
Neisseria meningitidis is the causative agent of invasive meningococcal disease (IMD). The BEXSERO® vaccine which is used to prevent serogroup B disease is composed of four sub-capsular protein antigens supplemented with an outer membrane vesicle. Since the sub-capsular protein antigens are variably expressed and antigenically variable amongst meningococcal isolates, vaccine coverage can be est...
