Introduction Nakaseomyces glabratus (formerly Candida glabrata) is a highly adaptable, haploid yeast that is a common commensal of the human gastrointestinal and genitourinary tracts. It is the second or third most common cause of candidiasis worldwide and is notable for its high level of intrinsic and acquired …
Introduction Pichia kudriavzevii, formerly known as Candida krusei, is a unique budding yeast that holds a dual status as both a critical industrial organism and an emerging opportunistic pathogen. Taxonomy: It is the teleomorph (sexual state) of Candida krusei. It has also been historically known as Issatchenkia orientalis. …
Introduction Molecular typing of fungi uses DNA-based methods to identify species and differentiate strains for clinical, epidemiological, and environmental studies. Key techniques include Internal Transcribed Spacer (ITS) sequencing (the standard for identification), Multilocus Sequence Typing (MLST), restriction fragment length polymorphism (RFLP), and Whole Genome Sequencing (WGS). These methods are crucial for tracking …
Introduction HiCrome™ Candida Differential Agar is a specialized chromogenic medium used in clinical microbiology for the rapid isolation and presumptive identification of Candida species. The medium is designed to differentiate between major Candida species—Candida albicans, Candida tropicalis, Candida krusei (Pichia kudriavzevii), and Candida glabrata—based on colony color and morphology within 48 hours. …
Introduction The Dalmau plate technique is a classic mycological method used to identify and differentiate yeast species, specifically Candida species, by observing their unique morphological features. The technique is a specialized culture method that uses a “starvation medium” to induce the formation of characteristic structures like pseudohyphae, blastoconidia, and chlamydospores. It remains …
Introduction Sabouraud Dextrose Agar (SDA) is a commonly used culture medium in clinical mycology laboratories for the isolation of fungi, particularly yeasts and molds. Due to its acidic pH and high dextrose concentration, SDA favors fungal growth; however, bacteria and yeasts may also grow, especially …
Introduction Sterility testing in a GMP-compliant mycology laboratory is a critical quality assurance process used to confirm that pharmaceutical products, culture media, reagents, water systems, and laboratory environments are free from viable microorganisms, including fungi and yeasts.It follows regulatory guidelines defined by WHO, EU-GMP, USP …
Introduction KOH mount (Potassium Hydroxide preparation) is a rapid, simple, and cost-effective microscopic technique used to detect fungal elements directly in clinical specimens.When applied to Bronchoalveolar Lavage (BAL) samples, it is an essential diagnostic tool for identifying pulmonary fungal infections, especially in the ICU, oncology, …
