In vitro activities of antifungal agents alone and in combination against fluconazole-susceptible and -resistant strains of Candida dubliniensis.

In the present study we used two groups of Candida dubliniensis strains: one containing fluconazole-susceptible clinical isolates and another containing fluconazole-resistant laboratory derivative from the former to examine the changes on susceptibility accompanying the development of resistance to fluconazole. Our findings confirmed the ability of C. dubliniensis isolates to become resistant to fluconazole and indicated that this resistance was crossed with ketoconazole, itraconazole, ravuconazole and terbinafine.

Differentiation of Candida dubliniensis from Candida albicans with the use of killer toxins.

The aim of this study was to report the ability of killer toxins, previously used as biotyping techniques, as a new tool to differentiate C. albicans from C. dubliniensis.

Candida dubliniensis: epidemiology and phenotypic methods for identification.

Candida dubliniensis is an emerging pathogen first described in 1995, which shares many phenotypic features with Candida albicans and therefore may be misidentified in microbial laboratories. Despite various phenotypic techniques described in the literature to differentiate the two species, the correct identification of C. dubliniensis remains problematic due to phenotypic similarities between these species.

Candida 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.

In vitro activity of essential oils extracted from plants used as spices against fluconazole-resistant and fluconazole-susceptible Candida spp.

In the present study, the antifungal activity of selected essential oils obtained from plants used as spices was evaluated against both fluconazole-resistant and fluconazole-susceptible Candida spp. The Candida species studied were Candida albicans, Candida dubliniensis, Candida tropicalis, Candida glabrata, and Candida krusei. For comparison purposes, they were arranged in groups as C.

[New selective indicator medium for detection of Aeromonas and Plesiomonas: UNISC agar].

We evaluated a new selective indicator medium (UNISC Agar) for isolation of classical enteropathogens, Aeromonas spp and Plesiomonas shigelloides. The xylose fermentation capacity is indicated by a yellow color (fermenting agents) or blue (no fermenting agent). This, together with the oxidase test, establishes it as an indicator for detecting Aeromonas and Plesiomonas shigelloides.

Relationship between susceptibility of Candida spp. isolates to amphotericin B and death or survival of patients with candidemia episodes.

In this study, the susceptibility to amphotericin B of Candida spp. isolates obtained from patients with candidemia was related to their respective clinical outcomes. The susceptibility tests were carried out in three culture media: RPMI 1640, Antibiotic medium 3 and Yeast Nitrogen Base dextrose.

Enzymatic and hemolytic activities of Candida dubliniensis strains.

Candida dubliniensis is an opportunistic yeast that has been recovered from several body sites in many populations; it is most often recovered from the oral cavities of human immunodeficiency virus-infected patients. Although extensive studies on epidemiology and phylogeny of C. dubliniensis have been performed, little is known about virulence factors such as exoenzymatic and hemolytic activities.

Comparison among tomato juice agar with other three media for differentiation of Candida dubliniensis from Candida albicans.

The purpose of the present study is to compare the tomato juice agar, a well known medium employed to observe ascospore formation, with niger seed agar, casein agar and sunflower seed agar, applied to a differentiation between C. dubliniensis and C. albicans.

Carbohydrate assimilation profiles of Brazilian Candida dubliniensis isolates based on ID 32C system.

The purpose of the present study was to evaluate the identification of 19 Brazilian C. dubliniensis based on the biochemical profile exhibited when tested by the commercial identification kit ID 32C (bioMerieux). Thirteen of the isolates were rigorously identified as C.
