Fifty-nine Staphylococcus aureus isolates and 1 isolate of Staphylococcus intermedius were typed by investigators at eight institutions by using either antibiograms, bacteriophage typing, biotyping, immunoblotting, insertion sequence typing with IS257/431, multilocus enzyme electrophoresis, restriction analysis of plasmid DNA, pulsed-field or field(More)
Bacterial endocarditis is a serious medical complication of heroin addiction and should be suspected in any addict with a fever and positive blood cultures. However, gram-negative bacteria, and particularly Pseudomonas aeruginosa, are uncommon causes of bacterial endocarditis and their presence in a blood culture may be dismissed as a contaminant or as(More)
Two strains of Staphylococcus aureus expressing borderline or low-level methicillin resistance by one or more in vitro test methods were examined for resistance in vivo and for biochemical and genetic markers of methicillin resistance. In vivo, nafcillin was equally effective against experimental aortic valve endocarditis in rabbits, regardless of whether(More)
Rabbits with left-sided endocarditis due to Pseudomonas aeruginosa were treated with a high dose (7.5 mg/kg) of gentamicin for six days, a low dose (5 mg/kg) of gentamicin for six days or two weeks, carbenicillin (400 mg/kg) for six days or two weeks, or a combination of the lower dose of gentamicin and carbenicillin (400 mg/kg) for six days or two weeks.(More)
Intravenous miconazole, an investigational, broad-spectrum, antifungal imidazole drug, was clinically effective when used for the first time in a patient with life-threatening sporotrichosis. Miconazole was used after drug resistance and treatment failure occurred in a patient with extensive, cavitary, pulmonary infection with Sporotrichum schenckii. He had(More)
Rabbits with sterile, right ventricular cardiac vegetationss were challenged with Staphylococcus aureus and serum-susceptible or -resistant isolates of Pseudomonas aeruginosa. None of the rabbits challenged with serum-susceptible P. aeruginosa died or had greater than 10(2) colony-forming units (cfu)/g cultured from vegetations two weeks later. In contrast,(More)
In-vitro synergy testing was performed against ten blood or valve isolates of Staphylococcus epidermidis taken from patients with endocarditis. A three-dimensional microtitre checkerboard method was used for evaluation of vancomycin-rifampicin-gentamicin. The triple combination of vancomycin plus rifampicin plus gentamicin was found to be synergistic in 70%(More)
The efficacy of tobramycin in doses of 2.7 to 5.6 mg/kg per day in 29 courses of therapy in 25 hospitalized patients with serious Pseudomonas aeruginosa infections was studied. Eighty-three percent of the P. aeruginosa strains showed zones of inhibition of 16 mm or more around a 10-mug tobramycin disk in the Bauer-Kirby disk method. Tobramycin minimal(More)
A Mohammedan woman, aged 19, complained of abdominal pain of a very distressingcharacter. A tumour was present in the lower abdomen gradually increasing in size; and no menstruation. The woman had been deserted by her husband. Examination showed a movable tumour in the position and size of a fiva month's pregnancy. The vagina was shallow, about li inches in(More)
Snake fungal disease (SFD; Ophidiomyces ophiodiicola) is posing a significant threat to several free-ranging populations of pitvipers. Triazole antifungals have been proposed for the treatment of mycoses in reptiles; however, data are lacking about their safety and efficacy in snakes with SFD. Study 1 investigated in vitro susceptibility, and identified(More)
