The activity of fluconazole and amphotericin B against three isolates of Cryptococcus neoformans was evaluated, with fluconazole and amphotericin B MICs of 2.0-4.0 mg/L and 1.0 mg/L respectively, using time-kill curve methods. Fluconazole was fungistatic against all isolates tested (<99.9% decrease in cfu from initial inoculum). The fungistatic activity of(More)
We have previously described the activity of low-dose clindamycin in extended-interval dosing regimens by determination of bactericidal titer in serum. In this study, we used a one-compartment in vitro dynamic infection model to compare the pharmacodynamics of clindamycin in three intravenous-dosing regimens (600 mg every 8 h [q8h], 300 mg q8h, and 300 mg(More)

Posaconazole is an extended-spectrum azole antifungal that exhibits activity against a broad range of fungal pathogens, including yeasts and moulds. Clinical data have demonstrated the clinical utility of posaconazole against many therapy-refractory pathogens, including Aspergillus spp, Fusarium spp, and Zygomycetes. These data have provided clinicians with(More)
