Colony variation in Candida glabrata isolates from patients with vaginitis.

The ability of Candida glabrata to switch between different colony phenotypes on a Sabouraud's-chloramphenicol agar supplemented with phloxine B was assessed in 14 C. glabrata isolates. Three phenotypes (pale pink smooth, dark pink smooth and fuchsia petite) were observed in vitro and two of them (pale pink smooth and dark pink smooth) in fresh clinical isolates plated directly from vaginal specimens from patients with C.

A new method of antibiotyping yeasts for subspecies discrimination and distribution in human clinical specimens.

A study of the antibiotypes of 764 isolates of the genera Candida and Torulopsis from different clinical specimens is reported. The typing method was based on the susceptibility results obtained by the standardized and partially automated kit ATB-Fungus (API-bioMérieux), giving to each strain a code of six figures, according to these criteria: susceptibility to 5-fluorocytosine, amphotericin B, nystatin, miconazole, econazole, and ketoconazole. Candida albicans serotypes were determined by the Candida Check test (Iatron, Japan).

Candida biotypes in patients with oral leukoplakia and lichen planus. Candida biotypes in leukoplakia and lichen planus.

Prevalence of yeasts in 35 leukoplakia and 34 oral lichen planus patients was compared with that observed in persons without oral diseases. Serotype and morphotype were determined on Candida albicans isolates. Yeasts were isolated from the oral cavity specimens of 43.

[Assessment of the sensitivity to antifungal agents of clinical isolates of Candida albicans serotype A and B by the ATB Fungus method].

Background: Candida albicans is the most frequently species isolated in patients with candidiasis. This species may be antigenically divided in serotypes A and B, which have a different pathogenic behavior and antifungal susceptibility pattern.

Methods: The antifungal susceptibility of 443 clinical isolates from both serotypes of C.

Multicenter evaluation of ATB fungus: a standardized micromethod for yeast susceptibility testing.

The micromethod for yeast susceptibility testing, ATB Fungus, was evaluated with 30 reference strains in three laboratories. Ready-to-use strips with 5-fluorocytosine, amphotericin B, nystatin, miconazole, econazole and ketoconazole were used. The test allowed the categorization of each strain as susceptible, intermediate or resistance to all the antifungals tested, and 5-fluorocytosine and amphotericin B MIC determination.
