In vitro susceptibility of Haemophilus influenzae to trimethoprim-sulfamethoxazole.
Thirty-four strains of Haemophilus influenzae (20 ampicillin sensitive and 14 ampicillin resistant), mostly type b isolates from cerebrospinal fluid or blood, were tested for susceptibility to a combination of trimethoprim-sulfamethoxazole (TMP-SMZ) in a ratio of 1 part TMP to 19 parts SMZ. All strains were very susceptible to the TMP-SMZ combination, with minimal inhibitory concentrations rang...
متن کاملHaemophilus influenzae: antibiotic susceptibility.
Ampicillin resistance was first reported among clinical isolates of Haemophilus influenzae in 1972. Reports of chloramphenicol resistance followed shortly thereafter. The principal mechanism of resistance to these two antibiotics is enzymatic. Although other mechanisms have been described, they are found in comparatively few strains. The genetic information for the inactivating enzymes is plasm...
متن کاملSusceptibility testing of Haemophilus influenzae to clarithromycin.
Susceptibility testing of Haemophilus influenzae to the macrolide compounds has often been problematic. This is as a result of the inability of many isolates of H. influenzae to grow without the addition of 5% CO2 to the incubation atmosphere and the subsequent detrimental effect that CO2 has on the activity of the macrolide group of compounds. This report describes refinements and recommendati...
متن کاملAntimicrobial susceptibility of Haemophilus influenzae.
Selected clinical isolates of Haemophilus influenzae were tested for their susceptibility to seven antibiotics by a microtiter broth dilution and an agar diffusion method. Eleven of 40 strains tested were resistant to ampicillin, the drug of choice, by both methods. All the strains tested were susceptible to chloramphenicol, and all but one were susceptible to tetracycline. Of the other four an...
متن کاملIn vitro susceptibility of Haemophilus influenzae to sulfamethoxazole-trimethoprim and cefaclor, cephalexin, and cephradine.
Sulfamethoxazole-trimethoprim and three oral cephalosporins, cefaclor, cephalexin, and cephradine, were evaluated in vitro as possible alternatives to chloramphenicol in the treatment of non-central nervous system infections due to ampicillin-resistant Haemophilus influenzae. Sixty-four isolates of H. influenzae, including 31 beta-lactamase-positive strains, were tested by the agar dilution met...
