Editor's Pick MinireviewTherapeutic Challenges of Non-Aspergillus Invasive Mold Infections in Immunosuppressed PatientsWhile Aspergillus spp. remain the major cause of invasive mold infections in hematologic cancer patients and transplant recipients, other opportunistic molds, such as Mucorales, Fusarium, and Scedosporium spp. are increasingly encountered in an expanding population of patients with severe and prolonged immunosuppression. High potential for tissue invasion and dissemination, resistance to multiple...
Mechanisms of ResistanceThe Evolution of Azole Resistance in Candida albicans Sterol 14α-Demethylase (CYP51) through Incremental Amino Acid SubstitutionsRecombinant Candida albicans CYP51 (CaCYP51) proteins containing 23 single and 5 double amino acid substitutions found in clinical strains and the wild-type enzyme were expressed in Escherichia coli and purified by Ni2+-nitrilotriacetic acid agarose chromatography. Catalytic tolerance to...
Mechanisms of ResistanceVacuolar Sequestration of Azoles, a Novel Strategy of Azole Antifungal Resistance Conserved across Pathogenic and Nonpathogenic YeastTarget alteration and overproduction and drug efflux through overexpression of multidrug transporters localized in the plasma membrane represent the conventional mechanisms of azole antifungal resistance. Here, we identify a novel conserved mechanism of azole resistance not only in the budding yeast Saccharomyces cerevisiae but also in the pathogenic yeast...
Mechanisms of ResistanceRapid Detection of ERG11-Associated Azole Resistance and FKS-Associated Echinocandin Resistance in Candida aurisCandida auris is an emerging multidrug-resistant yeast that can cause serious invasive infections. The accurate and rapid assessment of antifungal resistance is important for effective patient management.
Mechanisms of ResistanceFirst Clinical Isolation of an Azole-Resistant Aspergillus fumigatus Isolate Harboring a TR46 Y121F T289A Mutation in South AmericaOne of the most recently described Aspergillus fumigatus CYP51A-mediated azole resistance mechanisms is TR46 Y121F T289A. Clinical A. fumigatus strains harboring these substitutions have been reported worldwide, with the exception of South America.
- Mechanisms of ResistanceMolecular Confirmation of the Linkage between the Rhizopus oryzae CYP51A Gene Coding Region and Its Intrinsic Voriconazole and Fluconazole Resistance
Rhizopus oryzae is the most prevalent causative agent of mucormycosis, an increasingly reported opportunistic fungal infection. These Mucorales are intrinsically resistant to Candida- and Aspergillus-active antifungal azole drugs...
