Introduction Multiplex Polymerase Chain Reaction (PCR) directly on Cerebrospinal Fluid (CSF) is an advanced molecular diagnostic technique designed to detect multiple pathogens simultaneously from a single CSF sample. It offers rapid, sensitive, and specific identification of bacterial, viral, and fungal agents responsible for central nervous …
Introduction Invasive mold infections caused by species such as Aspergillus, Fusarium, Scedosporium, and Mucorales pose serious challenges, especially in immunocompromised and oncology patients. Accurate antifungal susceptibility testing (AFST) is essential for guiding therapy and monitoring resistance trends. The EUCAST (European Committee on Antimicrobial Susceptibility Testing) …
Introduction Direct microscopic examination is one of the most rapid and inexpensive diagnostic methods for detecting fungal elements in clinical specimens. Potassium hydroxide (KOH) smear is a routine technique in mycology that helps visualize fungal structures such as hyphae, yeast cells, and sclerotic bodies directly …
Introduction Candidemia and invasive Candida infections are among the most common fungal diseases in hospitalized and immunocompromised patients. Traditional diagnosis by blood culture is often slow and has limited sensitivity. Candida antigen testing provides a rapid, non-culture-based method for detecting circulating fungal components in blood …
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 Yeast infections, particularly those caused by Candida, Cryptococcus, and other opportunistic yeasts, are significant in immunocompromised and oncology patients. Rapid and accurate identification of yeasts is essential for guiding therapy and improving patient outcomes. Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry (MALDI-TOF MS), …
Introduction Yeast infections, particularly caused by Candida and Cryptococcus species, are a major clinical challenge, especially in immunocompromised patients. Rapid and accurate determination of antifungal susceptibility is crucial for guiding therapy. The E-test (Epsilometer test) is a widely used, simple, and reliable method for determining …
Introduction of Comparison: Multiplex PCR vs Blood Culture vs Biomarker Tests The diagnosis of invasive fungal infections remains a major clinical challenge, especially in high-risk patients such as those with cancer, transplants, or critical illness. Conventional blood culture is still the gold standard but suffers …
