Detecting Low-Yield Target Fungal DNA from Bronchoalveolar Lavage Fluid: Sensitivity Limits of Conventional vs. Quantitative PCR

Detecting Low-Yield Target Fungal DNA from Bronchoalveolar Lavage Fluid: Sensitivity Limits of Conventional vs. Quantitative PCR

Introduction 0.5 ng/µL of DNA is detectable and can yield a positive result by PCR. In modern molecular diagnostics, PCR is incredibly sensitive. While 0.5 ng/µL might seem like a low concentration on a spectrophotometer (like a NanoDrop), it is actually a substantial amount of …

Geotrichum klebahnii: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, and Prevention

Lacking blastoconidia (budding yeast cells), distinguishing Geotrichum klebahnii from Trichosporon

Introduction Geotrichum klebahnii is a rare, opportunistic, yeast-like fungus that is found globally in environments like soil, dairy products, and organic waste, but can act as an emerging pathogen in humans. Along with Geotrichum candidum, it is one of the only species within its genus …

Trichosporon species: Introduction, Morphology, Medically Important Species, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes

A plastic petri dish containing a light-yellowish, finely wrinkled (cerebriform) and dry Trichosporon microbial culture with a flat, mealy (farinose) covering on PDA agar

Introduction Trichosporon is a genus of anamorphic, yeast-like basidiomycetous fungi widely distributed in nature, particularly in tropical and temperate regions. First identified by Beigel in 1865, it commonly exists as a saprophytic organism in soil, water, plants, and animal droppings. In humans, it is a …

Saprochaete capitata:Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes

Saprochaete capitata in Dalmau plate technique microscopic footage

Introduction Saprochaete capitata is an emerging opportunistic fungal pathogen that causes severe, frequently fatal systemic infections in profoundly immunocompromised individuals. It is notorious for its intrinsic resistance to echinocandins and high resistance to fluconazole, which often results in breakthrough fungemia during standard empirical antifungal therapy. …

Aspergillus terreus: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes

Colony morphology of Aspergillus terreus on Corn Meal Agar (CMA) showing a characteristic cinnamon-brown to sandy-beige pigmentation with a velvety, granular texture and a light-colored peripheral growth zone

Introduction & Taxonomy Aspergillus terreus is a filamentous fungus increasingly recognized as a significant emerging opportunistic pathogen. It is uniquely distinguished from other common species by its intrinsic resistance to amphotericin B, its characteristic cinnamon-brown colony color, and the production of specialized spores called aleurioconidia. …
