    ABSTRACT: The in vitro activity of ravuconazole (RVCZ) was compared with those of itraconazole (ITCZ) and terbinafine (TBF) against 73 dermatophyte isolates and 18 Candida spp. isolates recovered from patients with dermatomycosis at 4 dermatological clinics in Japan in 2011. The dermatophyte isolates consisted of Trichophyton rubrum (n=51), Trichophyton mentagrophytes (n=20 : these strains were not identified by molecular phylogenetic analysis.), Trichophyton tonsurans (n=1), and Microsporum canis (n=1). The Candida spp. isolates comprised C. albicans (n=11), C. parapsilosis (n=5), C. guilliermondii (n=1), and C. pseudohaemulonii (n=1). RVCZ was highly active against all dermatophytes and all Candida spp. : the geometric mean (GM) MICs for T. rubrum and T. mentagrophytes were 0.035 μg/mL and MICs for T. tonsurans and M. canis were ≤ 0.03μg/mL, and GM MICs for C. albicans and C. parapsilosis were ≤ 0.03μg/mL and MICs for C. guilliermondii and C. pseudohaemulonii were 0.25 and ≤ 0.03μg/mL, respectively. Compared to RVCZ, ITCZ showed similar anti-dermatophytic and anti-Candida activities, while TBF had a slightly higher anti-dermatophytic but a markedly lower anti-Candida activity. These results suggest that RVCZ is a potential candidate systemic antifungal therapy against onychomycosis and other dermatomycoses that are refractory to topical antifungal therapy.

    ABSTRACT: The in vitro antifungal activities of micafungin in comparison to caspofungin, fluconazole, itraconazole, voriconazole, and amphotericin B were evaluated against 93 Candida and 23 Aspergillus isolates recovered from pediatric patients with fungal infections. MICs were determined by the CLSI M27-A2 and M38-A for Candida and Aspergillus species, respectively. Micafungin showed potent activity against Candida albicans, Candida tropicalis, and Candida glabrata with a MIC range of <= 0.002 to 0.015mug/ml. In contrast, micafungin demonstrated higher MIC levels against Candida parapsilosis with a MIC range of 0.12 to 2 mug/ml. Micafungin showed potent antifungal activity against Aspergillus species tested with a MIC range of 0.004 to 0.015 mug/ml. Overall, micafungin had excellent in vitro antifungal activities against Candida and Aspergillus species recovered from pediatric patients with fungal infections.
