Introduction To Neisseriaceae

All pathogenic aerobic gram-negative cocci belong to the family of Neisseriaceae consisting of 5 genera include: Acinetobacter King Ella Moraxella (formerly Branhamella) Neisseria Oligella Neisseria contains the most important human pathogens: N. meningitidis N. gonorrhoeae Many saprophytic Neisseria can often be in the oropharynx provide evidence in the vagina or in the colon but rarely cause disease in humans. Moraxella catarrhalis causes otitis media in children, sinusitis in people of all ages and deteriorations of COPD and sometimes community-acquired pneumonia in adults and sporadic bacteremia. More than half a dozen other Moraxella sp. and the related King kingae infections of the CNS, respiratory, urinary tract, endocardium, the bones and joints can cause. The only known reservoir of Neisseria is man, the propagation takes place primarily through transfer from human to human. Both N. meningitidis (meningococcus) and N. gonorrhoeae (gonorrhea caused) can occur with an asymptomatic carrier state. A carrier state is particularly important in meningococcal disease, since this is associated with the occurrence of outbreaks.
