Cefoxitin, a semisynthetic cephamycin antibiotic: susceptibility studies.
Cefoxitin, 3-carbamoyloxymethyl-7-alpha-methoxy-7-[2-(2-thienyl)acetamido]-3-cephem-4- carboxylic acid, is a new semisynthetic cephamycin with broad antibacterial activity. It is highly active against gram-negative microorganisms including indole-positive Proteus and Serratia strains, which are ordinarily reistant to the cephalosporins. Cefoxitin is also highly active against many strains of Es...
متن کاملCefoxitin, a semisynthetic cephamycin antibiotic: resistance to beta-lactamase inactivation.
Cefoxitin is a new, cephalosporin-like antibiotic which is highly resistant to hydrolysis by beta-lactamase. Ninety-one cultures were selected either for their general resistance to cephalosporin antibiotics or for their ability to produce beta-lactamase. Some of these cultures were resistant to cefoxitin. The capacity of each of the 91 strains to hydrolyze cefoxitin with beta-lactamase was det...
متن کاملCefoxitin, a semisynthetic cephamycin antibiotic: antibacterial spectrum and resistance to hydrolysis by gram-negative beta-lactamases.
The in vitro activity of cefoxitin, 3-carbamolyloxymethyl-7-alpha-methoxy-7[2-(2-thienyl)acetamido]-3-cephem-4-carboyxlic acid, was investigated. Activity against gram-positive organisms was less than that of cephalothin and cephloridine. It was highly active against gram-negative bacilli, with activity against Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae equal to that of curr...
متن کاملCefoxitin, a new semi-synthetic cephamycin: an in-vitro and in-vivo comparison with cephalothin.
The activity of cefoxitin was compared with that of cephalothin against 229 bacterial strains. Cefoxitin was more active against most Gram-negative strains, notably against indole-producing Proteus spp., which are usually resistant to the cephalosporins. Cefoxitin was not susceptible to any significant extent to degradation by beta-lactamases produced by Gram-negative organisms. Against Gram-po...
متن کاملIn vitro and in vivo antibacterial activities of MT-141, a new semisynthetic cephamycin, compared with those of five cephalosporins.
The in vitro and in vivo antibacterial activities of MT-141 were compared with those of cefoxitin, cefmetazole, moxalactam, cefotaxime, and cefoperazone. The MICs of MT-141 for 90% of bacterial isolates were lower than the reference drugs against clinical isolates of Campylobacter jejuni, Clostridium difficile, and Bacteroides fragilis, whereas against clinical isolates of other gram-positive, ...
