Serum or bile affects the in vitro azole susceptibilities of Candida spp.
نویسندگان
چکیده
Drug susceptibility tests were performed with a series of Candida spp. in media supplemented with serum or bile. The azole susceptibilities of several medically important Candida spp., including C. albicans but not C. parapsilosis, were significantly reduced in supplemented media. These findings have important implications for the mechanisms of acquired azole resistance in pathogenic fungi.

Triazole cross-resistance among Candida spp.: case report, occurrence among bloodstream isolates, and implications for antifungal therapy.
Candida spp. are common causes of bloodstream infections among hospitalized patients. Fluconazole (FLC) remains a first-line therapy for candidemia; and voriconazole (VRC), an expanded-spectrum triazole, was recently approved for the treatment of candidemia in nonneutropenic patients. In vitro studies have suggested that VRC has potent activity against Candida spp. with reduced susceptibilities...
متن کاملIn vitro interactions of crocin with fluconazole against Candida isolates
Background and Purpose: The incidence of invasive fungal infections has been increased in recent years. The growing use of azole drugs for prophylactic and therapeutic purposes has resulted in the gradual emergence of azole-resistant species. Accordingly, the introduction of a new strategy to improve the management of Candida infections is an urgent need. Regarding this, the present study was p...
متن کاملIn vitro activity of the novel echinocandin CD101 at pH 7 and 4 against Candida spp. isolates from patients with vulvovaginal candidiasis
Background The novel echinocandin CD101 has stability properties amenable to topical formulation for use in the treatment of acute vulvovaginal candidiasis (VVC) and recurrent VVC (RVVC). CD101 has demonstrated potent antifungal activity at pH 7, but assessment of its activity at the physiological pH of the vaginal environment is needed. Objectives To evaluate the antifungal activity of CD101...
متن کاملClinical significance of azole antifungal drug cross-resistance in Candida glabrata.
Candida glabrata, which can become resistant to fluconazole, is a common cause of bloodstream infection. This study was performed to determine the significance of cross-resistance to new azole drugs among C. glabrata isolates recovered as a cause of infection in azole-treated hematopoietic stem cell transplant (HSCT) recipients. Seven cases of invasive candidiasis caused by C. glabrata occurred...

OBJECTIVES The objective of this study was to evaluate the in vitro activity of CD101, a novel echinocandin with a long serum elimination half-life, and comparator (anidulafungin and caspofungin) antifungal agents against a collection of Candida and Aspergillus spp. isolates. METHODS CD101 and comparator agents were tested against 106 Candida spp. and 67 Aspergillus spp. isolates, including 2...
