Plasminogen recruitment is a common strategy of pathogenic bacteria and results in a broad-spectrum surface-associated protease activity. Neisseria meningitidis has previously been shown to bind plasminogen. In this study, we show by several complementary approaches that endolase, DnaK, and peroxiredoxin, which are usually intracellular proteins, can also be located in the outer membrane and ac...

A carbohydrate fermentation plate medium is described for rapid and reliable confirmation of Neisseria gonorrhoeae, N. meningitidis, and other Neisseria species. The medium is based on a modification of NYC (U.S. Patent 3,846,241) medium, originally designed for the isolation of pathogenic Neisseria (3). A total of 715 clinical isolates were tested for their carbohydrate fermentation reactions ...

UNLABELLED Neisseria meningitidis, an exclusively human pathogen and the leading cause of bacterial meningitis, must adapt to different host niches during human infection. N. meningitidis can utilize a restricted range of carbon sources, including lactate, glucose, and pyruvate, whose concentrations vary in host niches. Microarray analysis of N. meningitidis grown in a chemically defined medium...

We describe the first case of Neisseria meningitidis W135 meningitis in Turkey. The strain was genotypically unrelated to the clone (W)ET-37, isolated from Hajj pilgrims in 2000.

Epidemiology There is general agreement that oropharyngeal infection occurs most frequently in homosexual men, followed by women and heterosexual men. The table gives comparative prevalences from four studies of patients with gonorrhoea. Weisner et al4 found the oropharyngeal isolation rate of neisseria species from his population was: N meningitidis 17.2%; N gonorrhoeae 5.6% and N lactamica 1 ...

Redundant TonB systems which function in iron transport from TonB-dependent ligands have recently been identified in several gram-negative bacteria. We demonstrate here that in addition to the previously described tonB locus, an alternative system exists for the utilization of iron from hemoglobin, transferrin, or lactoferrin in Neisseria meningitidis and Neisseria gonorrhoeae. Following incuba...

Background. Meningitis is a serious communicable disease with high morbidity and mortality rates. It is an endemic disease in Egypt caused mainly by Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. In some settings, bacterial meningitis is documented depending mainly on positive cerebrospinal fluid (CSF) culture results or CSF positive latex agglutination test, miss...
