background: there is little information about the prevalence and risk factors for neisseria gonorrhoeae in iran. the pur pose of this study was to determine the prevalence and risk factors of gonococcal infection in women in babol, north of iran. methods: five hundred- fifty married women, who were younger than 45 years, were assessed of aspects of hidden and obvi ous gonococcal infection. a sa...

During 1971 and 1972, 71 cultures of neisseriae that attacked lactose were received by this laboratory. All strains except one from an eye swab were from the nasopharynx of healthy subjects. Nineteen similar strains from the nasopharynx were isolated in this laboratory. The characteristics of these strains were compared with those of Neisseria meningitidis, Neisseria pharyngis, Neisseria catarr...

BACKGROUND Invasive meningococcal disease (IMD) is a major cause of bacterial meningitides and septicaemia. This study shows the results of the laboratory-based surveillance of IMD in Belgium over the period 1997-2012. METHODS The results are based on microbiological and molecular laboratory surveillance of 2997 clinical isolates of N. meningitides received by the Belgian Meningococcal Refere...

background neisseria lactamica as one of the main commensal in oropharynx during the childhood is related to the induction of a natural immunity against meningococcal meningitis. also moraxella catarrhalis in oropharynx of children is a predisposing factor for otitis media infection. objectives the current study aimed to investigate the frequency of the n. lactamica, other nonpathogenic neisser...

BACKGROUND Various materials have been proposed to obliterate dead spaces and to reconstruct dural defects during a neurosurgical approach. This study describes our technique of using the abdominal autologous fat graft and evaluates the complications and characteristics related to the use of this tissue during cranial procedures. METHODS Autologous fat grafts were used in 296 patients with ba...

The adhC gene from 11 strains of Neisseria gonorrhoeae was distinguished from its homologue in Neisseria meningitidis by the presence of a premature stop codon caused by a single base insertion. Mutational analysis showed that NADH S-nitrosoglutathione oxidoreductase activity was associated with adhC in Neisseria meningitidis but not in Neisseria gonorrhoeae.

Phylogenies generated from whole genome sequence (WGS) data provide definitive means of bacterial isolate characterization for typing and taxonomy. The species status of strains recently defined with conventional taxonomic approaches as representing Neisseria oralis was examined by the analysis of sequences derived from WGS data, specifically: (i) 53 Neisseria ribosomal protein subunit (rps) ge...

A new generation of vaccines containing multiple protein components that aim to provide broad protection against serogroup B meningococci has been developed. One candidate, 4CMenB (4 Component MenB), has been approved by the European Medicines Agency, but is predicted to provide at most 70-80 % strain coverage; hence there is a need for second-generation vaccines that achieve higher levels of c...
