Evolutionary accumulation of FKS 1 mutations from clinical echinocandin-resistant Candida auris

Emerging Microbes and Infections
Introduction: Drug resistance to echinocandins, first-line drugs used to treat Candida auris infection, is rapidly emerging. However, the accumulation of mutations in genes other than FKS1 (before an isolate develops to resistance via FKS1 mutations ...

Cryo-EM structure of the β-1,3-glucan synthase FKS1-Rho1 complex

Nature Communications
β-1,3 Glucan synthase (GS) is essential for fungal cell wall biosynthesis. The GS holoenzyme comprises the glycosyltransferase FKS1 and its regulatory factor Rho1, a small GTPase.

A benchmark dataset for validating FKS1 mutations in Candida auris [PDF]

Microbiology Spectrum
Echinocandins are the recommended antifungal therapy for Candida auris infections in many countries. While echinocandin resistance remains uncommon, recent reports demonstrate an increase in such cases, with the potential for echinocandin-resistant C ...

Differential Regulation of Echinocandin Targets Fks1 and Fks2 in Candida glabrata by the Post-Transcriptional Regulator Ssd1

Journal of Fungi, 2020
Invasive infections caused by the opportunistic pathogen Candida glabrata are treated with echinocandin antifungals that target β-1,3-glucan synthase, an enzyme critical for fungal cell wall biosynthesis. Echinocandin resistance develops upon mutation of

Evaluation of a Novel FKS1 R1354H Mutation Associated with Caspofungin Resistance in Candida auris Using the CRISPR-Cas9 System [PDF]

Journal of Fungi, 2023
Outbreaks of invasive infections, with high mortality rates, caused by multidrug-resistant Candida auris have been reported worldwide. Although hotspot mutations in FKS1 are an established cause of echinocandin resistance, the actual contribution of ...

Pan-Echinocandin Resistant C. parapsilosis Harboring an F652S Fks1 Alteration in a Patient with Prolonged Echinocandin Therapy

Journal of Fungi, 2022
The isolation of a pan-echinocandin-resistant Candida parapsilosis strain (anidulafungin, caspofungin, micafungin and rezafungin EUCAST MICs > 8 mg/L) from urine of a patient following prolonged exposure to echinocandins (38 days of micafungin followed ...

Do Candida albicans Isolates with Borderline Resistant Micafungin MICs Always Harbor FKS1 Hot Spot Mutations?

Journal of Fungi, 2021
Antifungal susceptibility testing is important in guiding patient therapy due to an increasing number of resistant Candida isolates. In the clinical strain collection of the Austrian resistance report (AURES), a high number of micafungin-resistant C ...

Fatal Breakthrough Candidemia in an Immunocompromised Patient in Kuwait Due to Candida auris Exhibiting Reduced Susceptibility to Echinocandins and Carrying a Novel Mutation in Hotspot-1 of FKS1

Journal of Fungi, 2022
Candida auris is an emerging yeast pathogen that has recently caused major outbreaks in healthcare facilities worldwide. Clinical C. auris isolates are usually resistant to fluconazole and readily develop resistance to echinocandins and amphotericin B ...

FKS1 Is Required for Cryptococcus neoformans Fitness In Vivo: Application of Copper-Regulated Gene Expression to Mouse Models of Cryptococcosis

mSphere, 2022
There is an urgent need for new antifungals to treat cryptococcal meningoencephalitis, a leading cause of mortality in people living with HIV/AIDS. An important aspect of antifungal drug development is the validation of targets to determine whether they ...
