Yeasts-Colorimetric Antifungal Susceptibility Testing: Introduction, Principle, Clinical Significance, and Keynotes

Yeasts-Colorimetric Antifungal Susceptibility Testing-Introduction, Principle, Clinical Significance, and Keynotes

Introduction Yeasts, especially Candida and Cryptococcus species, are frequent causes of opportunistic infections in immunocompromised patients. Determining their antifungal susceptibility is crucial for guiding effective therapy. While broth microdilution methods (CLSI/EUCAST) serve as reference standards, they are labor-intensive and time-consuming. Colorimetric antifungal susceptibility testing systems …

Yeasts (Disk Diffusion) Assay: Introduction, Test Requirements, Procedure, Result-Interpretation, and Keynotes

Yeasts (Disk Diffusion) Assay

Introduction Disk diffusion assay is a standardized method used for testing antifungal susceptibility of yeasts, especially Candida spp. It evaluates the inhibitory effect of antifungal agents on yeast growth by measuring the zone of inhibition around drug-impregnated disks placed on inoculated agar. This method is …
