Introduction Invasive mold infections such as those caused by Aspergillus, Fusarium, Scedosporium, and Mucorales present significant clinical challenges, especially in immunocompromised hosts. Mortality rates are high, and empirical antifungal therapy often fails due to intrinsic or acquired resistance. Standardized antifungal susceptibility testing (AFST) is therefore …
Introduction Fungal infections caused by yeasts, particularly Candida and Cryptococcus species, represent a significant clinical challenge in immunocompromised and critically ill patients. Antifungal susceptibility testing (AFST) is crucial for guiding therapy, particularly in cases of treatment failure or the emergence of resistance. The broth microdilution …
Introduction Fungal infections represent a growing concern in both immunocompromised and immunocompetent individuals. Conventional identification methods, including culture, microscopy, and biochemical testing, often require several days and may lack sensitivity or specificity for certain opportunistic fungi. Molecular techniques such as PCR and sequencing have improved …
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 …
Introduction of MDR Candida NGS MDR Candida NGS refers to the use of Next-Generation Sequencing for the detection, identification, and resistance gene profiling of multidrug-resistant (MDR) Candida species, such as Candida auris, Candida glabrata, and others resistant to azoles, echinocandins, or polyenes. Next-generation sequencing (NGS) …
Introduction Fungemia refers to the presence of fungi in the bloodstream, indicating systemic fungal infection. Candida species are most commonly responsible, but other yeasts and molds may also invade the bloodstream. Fungemia is a medical emergency, especially in ICU patients, immunocompromised hosts, post-surgical cases, and …
Introduction of Candida auris Screening in a Simple Setup Candida auris Screening in a Simple Setup is possible to presumptively identify Candida auris in a simple laboratory setup, though definitive identification typically requires advanced methods. In resource-limited or basic clinical microbiology labs, we can still …
Introduction Common invasive fungal pathogens that frequently affect cancer patients, especially those who are immunocompromised due to chemotherapy, hematologic malignancies, or bone marrow/stem cell transplants. List of Common Invasive Fungal Pathogens 1. Candida species Causes: Candidemia, disseminated candidiasisRisk: Neutropenia, central venous catheter, broad-spectrum antibiotics 2. …
