Single- and combination-antibiotic therapy for experimental endocarditis caused by methicillin-resistant Staphylococcus aureus.
The efficacy of fosfomycin in combination with vancomycin or gentamicin was evaluated in experimental endocarditis caused by methicillin-resistant Staphylococcus aureus. After 5 days of therapy, both combinations proved to be highly effective since all rabbits had sterile vegetations.
متن کاملClindamycin therapy of experimental Staphylococcus aureus endocarditis.
The efficacy of clindamycin in the treatment of experimental endocarditis in rabbits was compared with that of nafcillin. Both drugs were administered intramuscularly three times daily for 5 days, clindamycin at doses of 6.25, 12.5, 25, or 50 mg/kg and nafcillin at a dose of 200 mg/kg. The minimum inhibitory and bactericidal concentrations (0.125 microgram/ml) of clindamycin for the test strain...
متن کاملAntibiotic therapy of experimental Staphylococcus epidermidis endocarditis.
Endocarditis was produced in rabbits with a methicillin-resistant Staphylococcus epidermidis isolate. Subpopulations resistant to other semisynthetic penicillins and cephalosporins were detected in the isolate. Their presence was probably responsible for the increase in minimum bactericidal concentrations and minimum inhibitory concentrations when tests with high inocula, rather than low inocul...
متن کاملEfficacy of fleroxacin in experimental methicillin-resistant Staphylococcus aureus endocarditis.
The efficacy of fleroxacin versus that of vancomycin was assessed by using the rabbit model of methicillin-resistant Staphylococcus aureus endocarditis. Animals were treated with fleroxacin (30 mg/kg of body weight every 8 h) or vancomycin (17.5 mg/kg every 6 h) for 4 days. These antimicrobial agents were equally effective in clearing bacteremia, reducing bacterial counts in vegetations and tis...
متن کاملCombination antibiotic treatment of serious methicillin-resistant Staphylococcus aureus infections.
Outcomes from methicillin-resistant Staphylococcus aureus (MRSA) infections are relatively poor, at least in part due to the limitations of vancomycin (the current standard treatment for MRSA). Combination antibiotic treatment for MRSA infections is an attractive alternative as it could address most of vancomycin's shortcomings, including poor tissue penetration, slow bacterial killing, and eme...
