Mechanisms of ResistanceLink between Heat Shock Protein 90 and the Mitochondrial Respiratory Chain in the Caspofungin Stress Response of Aspergillus fumigatusAspergillus fumigatus is an opportunistic mold responsible for invasive aspergillosis. Triazoles (e.g., voriconazole) represent the first-line treatment, but emerging resistance is of concern.
Mechanisms of ResistanceA Systematic Screen Reveals a Diverse Collection of Medications That Induce Antifungal Resistance in Candida SpeciesThe increasing incidence of and high mortality rates associated with invasive fungal infections (IFIs) impose an enormous clinical, social, and economic burden on humankind. In addition to microbiological resistance to existing antifungal drugs, the large number of unexplained treatment failures is a serious concern.
SusceptibilityDetection of Echinocandin-Resistant Candida glabrata in Blood Cultures Spiked with Different Percentages of FKS2 MutantsInfections caused by the coexistence of Candida glabrata echinocandin-resistant and echinocandin-susceptible cells may be possible, and the detection of FKS mutants when the proportions of FKS mutants are underrepresented poses a problem. We assessed the role of EUCAST and methods directly performed on positive blood cultures—Etest (ETDIR...
SusceptibilitySite-Directed Mutagenesis of the 1,3-β-Glucan Synthase Catalytic Subunit of Pneumocystis jirovecii and Susceptibility Assays Suggest Its Sensitivity to CaspofunginThe echinocandin caspofungin inhibits the catalytic subunit Gsc1 of the enzymatic complex synthesizing 1,3-β-glucan, an essential compound of the fungal wall. Studies with rodents showed that caspofungin is effective against Pneumocystis asci.
SusceptibilityAPX001A In Vitro Activity against Contemporary Blood Isolates and Candida auris Determined by the EUCAST Reference MethodAPX001A is the active moiety of the first-in-class drug candidate APX001. So far, most susceptibility testing studies have examined ≤30 isolates/species, and only one used the EUCAST method.
