Haemophilus influenzae type b meningitis resistant to ampicillin and chloramphenicol.
We report two cases of meningitis due to Haemophilus influenzae type b resistant to ampicillin and chloramphenicol. In one child the meningitis was preceded by pneumonia and pleural effusion. Both children responded to treatment with cefotaxime.

A case of ampicillin and chloramphenicol resistant Haemophilus influenzae meningitis successfully treated with cefotaxime is described.
متن کاملCharacterization of an ampicillin-resistant Haemophilus influenzae type B.
A 28-year-old female in Denver was found in early 1974 to have frontal sinusitis, osteomyelitis, and bacteremia due to Haemophilus influenzae, type B. The minimal inhibitory concentration of ampicillin for this organism was 100 mug/ml and the minimal bactericidal concentration was >100 mug/ml. It was inhibited by chloramphenicol at 0.4 mug/ml. Further studies demonstrated that ampicillin and me...
متن کاملSusceptibility of Haemophilus influenzae type b to cefatrizine, ampicillin, and chloramphenicol.
The susceptibility of 269 isolates of Haemophilus influenzae type b to cefatrizine (BL-S640), ampicillin, and chloramphenicol was evaluated by disk diffusion susceptibility tests, using a modified Bauer-Kirby method. Broth dilution susceptibility tests were performed on 88 of these isolates, including all isolates resistant by disk to cefatrizine or ampicillin. Six of the isolates were resistan...
متن کاملCombined action of chloramphenicol and ampicillin on chloramphenicol-resistant Haemophilus influenzae.
The interaction of ampicillin and chloramphenicol on three ampicillin-susceptible, chloramphenicol-resistant strains of Haemophilus influenzae was studied by checkerboard testing with subcultures, time-kill experiments, and a disk method. In all three strains there was inhibition of the bactericidal action of ampicillin by chloramphenicol at concentrations close to the MIC (10 micrograms/ml). T...
