Neisseria meningitidis serogroups A, B, C, W, X, and Y cause outbreaks of meningococcal disease. Quadrivalent conjugate vaccines targeting the are available. A pentavalent vaccine that also includes serogroup X (NmCV-5) is under development.

Background: Artificial oligonucleotides like DNA or RNA aptamers can be used as biodiagnostic alternatives for antibodies to detect pathogens. Comparing to antibodies, artificial oligonucleotides are produced easily at lower costs and are more stable. Neisseria meningitidis, the causative agent of meningitis, is responsible for about 1% of infections in an epidemic period. Specific DNA aptamers...

Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in humans. Currently, there are no vaccines to prevent disease caused by strains of N.meningitidis serogroup B. The Class 1 Outer Membrane Protein (OMP) has been named porA which is a cation selective transmembrane protein of 45 KDa that forms trimeric pore in the meningococcal outer membrane. PorA from ser...

introduction: the aim of this study was to setup, optimize and introduce a sensitive and specific pcr detection method for identification of neisseria meningitidis dna in clinical samples. material and methods: capsular transport gene a (ctra) was selected as a specific target sequence. this primer pair amplifies 101bp of the target gene. neisseria meningitidis strain: atcc; 13090 and neisseria...

Among 384 patients with confirmed meningococcal disease, the likelihood of detecting Neisseria meningitidis DNA in cerebrospinal fluid (CSF) increased with age, serogroup B infection, and prehospitalization antibiotic treatment. Plasma and CSF genomic bacterial loads of non-B N. meningitidis serogroups correlated significantly. Serogroup B-infected patients with genotype TNF2 (-308A) had signif...

conclusions these results show the usefulness of proteome analysis in successful identification of the common proteins between n. lactamica strains and nmb. this proteomics analysis is the starting point in the path of knowledge development about whole proteome profiles of n. lactamica strains. objectives the main aims of this study were to determine whole proteome profiles of n. lactamica stra...

Serogroup B Neisseria meningitidis strains belonging to sequence type 4821 clonal complex (CC4821), a hyperinvasive lineage first identified for serogroup C in 2003, have been increasingly isolated in China. We characterized the outer membrane protein genes of 48 serogroup B and 214 serogroup C strains belonging to CC4821 and analyzed the genomic sequences of 22 strains. Four serogroup B strain...
