Expression of pathogen-like Opa adhesins in commensal Neisseria: genetic and functional analysis

Abstract excerpt

Several species of commensal Neisseriae (Cn) may colonize the human nasopharynx, but little is known about their adhesion mechanisms. We have investigated structural and functional similarities between adhesins of Cn and of Neisseria meningitidis (Nm), also a frequent colonizer of the nasopharynx. In this study, we demonstrate the expression of Opa-like proteins in nine strains of Cn. Phylogenetic analysis...
