Distribution of transferrin binding protein B gene (tbpB) variants among Neisseria species

Background Transferrin binding protein B (tbpB), an outer membrane lipoprotein, is required for the acquisition of iron from human transferrin. Two tbpB families have been documented in Neisseria meningitidis: an isotype I tbpB gene of 1.8 kb and an isotype II tbpB gene of 2.1 kb, the former expressed by meningococci in the disease-associated ST-11 clonal complex and the latter...

Structural Alterations in a Component of Cytochrome c Oxidase and Molecular Evolution of Pathogenic Neisseria in Humans

Three closely related bacterial species within the genus Neisseria are of importance to human disease and health. Neisseria meningitidis is a major cause of meningitis, while Neisseria gonorrhoeae is the agent of the sexually transmitted disease gonorrhea and Neisseria lactamica is a common, harmless commensal of children. Comparative genomics have yet to yield clear insights...

Epidemiological Evidence for the Role of the Hemoglobin Receptor, HmbR, in Meningococcal Virulence

The distribution of the hemoglobin receptor gene (hmbR) was investigated among disease and carriage Neisseria meningitidis isolates, revealing that the gene was detected at a significantly higher frequency among disease isolates than among carriage isolates. In isolates without hmbR, the locus was occupied by the cassettes exl2 or exl3 or by a “pseudo hmbR” gene, designated exl4...

Phasevarions Mediate Random Switching of Gene Expression in Pathogenic Neisseria

Many host-adapted bacterial pathogens contain DNA methyltransferases (mod genes) that are subject to phase-variable expression (high-frequency reversible ON/OFF switching of gene expression). In Haemophilus influenzae, the random switching of the modA gene controls expression of a phase-variable regulon of genes (a “phasevarion”), via differential methylation of the genome in the...
