In vitro evaluation of cefoxitin and cefamandole.
Cefoxitin and cefamandole were evaluated in vitro against 263 organisms. Studies were performed in Mueller-Hinton and nutrient broth and agar employing inoculum sizes of 10(6) and 10(8) organisms per ml. At obtainable serum levels both antibiotics were bactericidal for nearly all strains of Escherichia coli, Klebsiella, Proteus mirabilis, and Staphylococcus aureus but were inactive against Pseu...
متن کاملIn vitro comparison of cefoxitin, cefamandole, cephalexin, and cephalothin.
The in vitro effect of cefoxitin, cefamandole, cephalexin, and cephalothin was tested against 645 strains of bacteria recently isolated from clinical sources. Against gram-positive organisms cephalothin and cefamandole were the most effective, generally being three- to fourfold more active than cephalexin or cefoxitin. Enterococci were not inhibited by less than 25 mug of any of the antibiotics...
متن کاملComparison of the in vitro activities of HR756 with cephalothin, cefoxitin, and cefamandole.
The in vitro activity of HR756, a new semisynthetic cephalosporin, was compared with the activities of cephalothin, cefoxitin, and cefamandole against 1,535 isolates of gram-positive and gram-negative bacteria. HR756 was less active than cephalothin and cefamandole and twofold more active than cefoxitin against Staphylococcus. All four of the antibiotics were inactive against the enterococcus g...
متن کاملIn vitro studies of cefamandole.
Cefamandole is a new cephalosporin antibiotic that was tested in vitro against 540 clinical isolates of gram-positive cocci and gram-negative bacilli. A concentration of 0.39 mug/ml inhibited 95% of the isolates of Staphylococcus aureus. A concentration of 6.25 mug/ml inhibited over 90% of the isolates of Proteus mirabilis and Escherichia coli, 69% of the isolates of Klebsiella pneumoniae, and ...
متن کاملAntagonism of carbenicillin and cefamandole by cefoxitin in treatment of experimental infections in mice.
The ability of cefoxitin to antagonize the in vivo efficacy of cefamandole and carbenicillin as predicted by in vitro assays was analyzed in experimental infections in mice. Cefoxitin was administered in a nonprotective dose either at the time of challenge or simultaneously with the protective drug, 1 and 3.5 h postchallenge. In mice infected with Enterobacter cloacae, median 50% protective dos...
