Candida albicans and Candida dubliniensis respond differently to echinocandin antifungal agents in vitro.
Candida dubliniensis isolates tested for susceptibility to anidulafungin, caspofungin, and micafungin commonly showed artifactual regrowth and/or trailing effects with MIC tests done under conditions involving a high initial yeast concentration. The artifacts were less common with Candida albicans and seldom seen for either species under Clinical and Laboratory Standards Institute method M27-A ...
متن کاملCandida dubliniensis does not show phospholipase activity: true or false?
INTRODUCTION The phospholipase activity in Candida albicans and Candida dubliniensis isolated from oral candidiasis cases were studied. METHODS The phospholipase activity was evaluated in egg yolk agar. RESULTS All the C. albicans isolates (n = 48) showed phospholipase activity (mean Pz = 0.66). However, none of the C. dubliniensis isolates (n = 24) showed this activity. CONCLUSIONS The a...
متن کاملIn vitro susceptibilities of Candida dubliniensis isolates tested against the new triazole and echinocandin antifungal agents.
Candida dubliniensis is a newly recognized fungal pathogen causing mucosal disease in AIDS patients. Although preliminary studies indicate that most strains of C. dubliniensis are susceptible to established antifungal agents, fluconazole-resistant strains have been detected. Furthermore, fluconazole-resistant strains are easily derived in vitro, and these strains exhibit increased expression of...
متن کاملOverexpression of Candida albicans CDR1, CDR2, or MDR1 does not produce significant changes in echinocandin susceptibility.
The micafungin and caspofungin susceptibilities of Candida albicans laboratory and clinical isolates and of Saccharomyces cerevisiae strains stably hyperexpressing fungal ATP-binding cassette (ABC) or major facilitator superfamily (MFS) transporters involved in azole resistance were determined using three separate methods. Yeast strains hyperexpressing individual alleles of ABC transporters or ...
متن کاملEchinocandin Resistance in Candida.
Invasive fungal infections are an important infection concern for patients with underlying immunosuppression. Antifungal therapy is a critical component of patient care, but therapeutic choices are limited due to few drug classes. Antifungal resistance, especially among Candida species, aggravates the problem. The echinocandin drugs (micafungin, anidulafungin, and caspofungin) are the preferred...
