N. meningitidis serogroups

Neisseria meningitidis, or meningococcus, is a bacteria that can cause serious infections like meningitis. It is classified into different serogroups based on components on its surface, mainly the polysaccharide capsule. There are several common serogroups, such as A, B, C, W, X, and Y. Each serogroup can trigger different patterns of disease and varies in geographical prevalence. Vaccines are available that target specific serogroups, helping prevent infections caused by those particular types of meningococcus. Understanding these serogroups aids in tailoring prevention and control strategies for meningococcal disease.
