Neisseria lactamica : ウィキペディア英語版 | Neisseria lactamica
''Neisseria lactamica'' is a gram-negative diplococcus bacterium. It is strictly a commensal species of the nasopharynx. Uniquely among the ''Neisseria'' they are able to produce β-D-galactosidase and ferment lactose. This species is most commonly carried by young children. There is an inverse relationship between colonisation by ''N. lactamica'' and ''Neisseria meningitidis''. Carriage of ''N. lactamica'' has been associated with decreased incidence of invasive meningococcal disease. However, resistance to penicillin and other beta-lactams may be transmitted from commensal neissseriae such as ''Neisseria lactamica'' to disease causing ''Neisseria meningitides'' by the process of genetic transformation. == References ==
