Introduction KOH mount of sputum is a rapid, direct microscopic technique used to detect fungal elements in the respiratory tract. A 10–20% Potassium Hydroxide (KOH) solution digests mucus, epithelial cells, and debris in sputum, while preserving the chitin-rich fungal cell walls, making them appear clear, …
Introduction Aspergillus species, particularly Aspergillus fumigatus, are major causes of invasive aspergillosis (IA), especially in immunocompromised patients, such as those with hematological malignancies, transplant recipients, or those with prolonged neutropenia. Diagnosis of IA is often challenging because clinical symptoms and radiological findings are nonspecific. Aspergillus …
Introduction Molds such as Aspergillus, Fusarium, Scedosporium, and members of the Mucorales are important causes of invasive fungal infections, particularly in immunocompromised patients (oncology, transplant, hematology, ICU). Unlike yeasts (Candida, Cryptococcus), which are more frequently recovered from blood cultures, molds are rarely detected in routine …
Introduction Pneumocystis PCR is a molecular diagnostic tool used for the detection of Pneumocystis jirovecii DNA in respiratory specimens, especially in immunocompromised patients suspected of having Pneumocystis pneumonia (PCP).It offers higher sensitivity than traditional staining techniques (e.g., GMS, toluidine blue) and is particularly helpful in …
Introduction Fungal pneumonia or invasive fungal pulmonary infection is often life-threatening, especially in immunocompromised patients, such as those with cancer, undergoing chemotherapy, or with HIV/AIDS. pulmonary inflammation caused by inhaled fungal spores or hematogenous fungal spread, leading to pneumonia-like illness. Common Fungi Causing Pulmonary Infections: …
