Antibiotic susceptibility of Neisseria meningitidis strains isolated in Makkah, Saudi Arabia

الملخص EN

The antimicrobial activity of 10 antibiotics against 42 Group a Neisseria meningitidis strains beta-lactamase non-producing was determined using the disc diffusion method and dilution technique.

All isolates were sus¬ceptible by the DDM to .penicillin, ampidllin, cefuroxime, ceftriaxone, cef¬otaxime, chloramphenicol ciprofloxacin, and rifampirin.

Thirty-two (76 %) were resistant to sulphamethoxazole and trimethoprim / sulphamethoxazole.

MICs of the isolates showed that ceftriaxone, cefuroxime, and cefotaxime had greater inhibitory activities than penicillin or rifampicin.
