The susceptibility of 3432 meningococcal strains isolated from patients in the recent epidemic wave (1978–86) in Spain, to several antimicrobial agents used in the treatment and chemoprophylaxis of meningococcal infection has been tested. Most were resistant to sulphadiazine but sensitive to other antibiotics. The possible existence of a new pattern of behaviour of meningococcal to penicillin is discussed.7 p.application/pdfeng(c) Cambrigde University Press, 1987Neissèria de la meningitisPenicil·linaNeisseria meningitidisPenicillininfo:eu-repo/semantics/article2018-07-25info:eu-repo/semantics/openAccess3119361
