The Opc protein is encoded by a single gene, opcA, which is only expressed in N. meningitidis. The structure of Opc was solved in 2002 and, like Opa proteins, it is a β-barrel protein but with five surface-exposed loops (Figure 3B) . WebNeisseria meningitidis is remarkable for the diversity of interactions that the bacterium has with the human host, ranging from asymptomatic nasopharyngeal colonisation affecting virtually all members of the population; through focal infections of the meninges, joints, or eye; to the devastating and often fatal syndrome of meningococcal septic shock and …
WebNeisseria meningitidis exists in the nasopharynx of about 5-10% of the population and rarely causes serious disease.
