چکیده
This study compared difloxacin administered orally, enoxacin administered orally, and cefazolin administered intramuscularly for the treatment of experimental Staphylococcus aureus endocarditis. Difloxacin significantly reduced bacterial counts of vegetations compared with enoxacin. This study demonstrated that difloxacin was significantly more effective than enoxacin and as effective as cefazolin for the treatment of S. aureus endocarditis in rabbits.

Comparison of difloxacin, enoxacin, and cefoperazone for treatment of experimental Enterobacter aerogenes endocarditis.
This study compared difloxacin administered orally, enoxacin administered orally, and cefoperazone administered intramuscularly for the treatment of experimental Enterobacter aerogenes endocarditis. Difloxacin significantly reduced bacterial counts of vegetations, as compared with enoxacin and cefoperazone. Enoxacin and cefoperazone did not differ significantly. This study demonstrated that dif...
متن کاملTreatment of experimental Staphylococcus aureus endocarditis: comparison of cephalothin, cefazolin, and methicillin.
The effectiveness of cefazolin in Staphylococcus aureus endocarditis has been questioned because of in vitro inactivation by staphylococcal beta-lactamase. Cefazolin, although inactivated in vitro by S. aureus beta-lactamase, was as effective as cephalothin in the treatment of left-sided S. aureus endocarditis in rabbits. Cefazolin (20 mg/kg every 6 or 8 h), cephalothin (40 mg/kg every 6 h), an...
متن کاملRelative efficacies of broad-spectrum cephalosporins for treatment of methicillin-susceptible Staphylococcus aureus experimental infective endocarditis.
The effects of treatment with broad-spectrum parenterally administered cephalosporins and cefuroxime, cefazolin, or nafcillin were compared in an experimental model of Staphylococcus aureus infective endocarditis, and the results in vivo were compared with the activities of the study drugs in vitro. After 3 days of treatment, all antimicrobial agents tested were more effective than no treatment...
متن کاملIn Vivo Effects of Cefazolin, Daptomycin, and Nafcillin in Experimental Endocarditis with a Methicillin-Susceptible Staphylococcus aureus Strain Showing an Inoculum Effect against Cefazolin.
Several reports have implicated the inoculum effect that some strains of type A beta-lactamase (Bla)-producing, methicillin-susceptible Staphylococcus aureus (MSSA) show against cefazolin as the cause for clinical failures in certain serious deep-seated infections. Here, using a previously reported MSSA strain displaying this phenotype (TX0117), we obtained a Bla-cured derivative (TX0117c) with...
متن کاملComparison of ceforanide, cefazolin, methicillin, and nafcillin in Staphylococcus aureus endocarditis therapy in rabbits.
Ceforanide (30 mg/kg) administered every 12 h, cefazolin (20 mg/kg) administered every 8 h and methicillin or nafcillin (40 mg/kg) administered every 6 h were equally effective in reducing the number of Staphylococcus aureus in vegetations in rabbits with endocarditis. These treatments were more effective than methicillin or nafcillin administered every 12 h. Ceforanide produced higher peak con...
