Purpose of Review

The purpose of this review is to contribute to the knowledge about the existence of Candida auris as an emerging pathogenic fungus, multi-resistant to antifungal, and causing health care-associated infections (HCAI).

Recent Findings

C. auris emerges as yeast with clonal transmission resistance to three families of commonly used antifungals, mainly azoles (fluconazole and voriconazole), diminishing therapeutic options for the treatment of fungal infections. In 2009, C. auris was isolated for the first time in Japan and by the time of this review, it has been reported in different countries in Africa, America, Asia, and Europe.

Summary

It is important to identify yeasts of the Candida genus up to species, to perform susceptibility tests and to implement surveillance, prevention, and control measures, to minimize the global spread of this fungus, due to its impact on public health.

The aim of this study was to investigate the frequency and antifungal susceptibility of Candida clinical isolations coming from patients with candidiasis in six health care centers of Caracas, Venezuela metropolitan area. The laboratory reports were retrospectively revised from January 2003 through August 2005. The isolated yeasts identification was carried out by conventional methods and antifungal susceptibility was evaluated by ATB-fungus (bioMérieux, France) and Etest (AB Biodisk, Solna, Sweden). One thousand nine hundred seventy seven (1.977) yeasts were studied and their susceptibility testing were carried out only in 1,414 of them. C. albicans was the most isolated yeast (46.7%) and none-albicans Candida-species represented more than half of the isolations (53.4%). All the isolated yeasts evaluated presented CMIs<1 microg/ml to anfotericina B and showed variable susceptibility percentages to fluconazole (91.5%), itraconazole (80%) and voriconazole (98.6%).  相似文献

Purpose of Review

The purpose of this review is to provide a current view of the importance of the determination and use of epidemiological cutoff values (ECVs) for Cryptococcus neoformans, since there are no clinical breakpoints (CBPs).

Recent Findings

ECVs have been proposed for some antifungal agents and C. neoformans, using standardized methodologies by the Clinical and Laboratory Standards Institute (CLSI) and by the European Committee for Antimicrobial Susceptibility Testing (EUCAST), based on the distribution of minimum inhibitory concentrations (MICs). There is no sufficient evidence for the determination of ECVs for C. neoformans using commercial methods; however, as these methods are routinely used in the microbiology laboratory, it is recommended for the establishment of local ECVs using these methods and following the criteria for their determination.

Summary

Due to the geographic and genetic variations inherent to C. neoformans, it is important to calculate ECVs, since they are useful in clinical practice to guide therapy in the absence of CBPs.
