Performance of panfungal--and specific-PCR-based procedures for etiological diagnosis of invasive fungal diseases on tissue biopsy specimens with proven infection: a 7-year retrospective analysis from a reference laboratory.
نویسندگان
چکیده
A retrospective analysis of real-time PCR (RT-PCR) results for 151 biopsy samples obtained from 132 patients with proven invasive fungal diseases was performed. PCR-based techniques proved to be fast and sensitive and enabled definitive diagnosis in all cases studied, with detection of a total of 28 fungal species.

Development and clinical application of a panfungal PCR assay to detect and identify fungal DNA in tissue specimens.
Given the rise in the incidence of invasive fungal infections (IFIs) and the expanding spectrum of fungal pathogens, early and accurate identification of the causative pathogen is essential. We developed a panfungal PCR assay that targets the internal transcribed spacer 1 (ITS1) region of the ribosomal DNA gene cluster to detect fungal DNA in fresh and formalin-fixed, paraffin-embedded (PE) tis...
متن کاملPanfungal PCR assay for detection of fungal infection in human blood specimens.
A novel panfungal PCR assay which detects the small-subunit rRNA gene sequence of the two major fungal organism groups was used to test whole-blood specimens obtained from a series of blood or bone marrow transplant recipients. The 580-bp PCR product was identified after amplification by panfungal primers and hybridization to a 245-bp digoxigenin-labeled probe. The lower limit of detection of t...

Background and Aim: Fungal rhinosinusitis (FRS) sets in following interactivity of fungi with Sino nasal tract when immune system is subdued. Due to varied clinical presentation of FRS with inconclusive evidence of imaging, mycological evaluation helps to identify and speciate the fungi .FRS can be diagnosed with biopsy tissue and/or deep nasal swabs. This study was undertaken to know risk fact...
متن کاملPerformances of two different panfungal PCRs to detect mould DNA in formalin-fixed paraffin-embedded tissue: what are the limiting factors?
BACKGROUND Detection of fungal DNA from formalin-fixed, paraffin-embedded (FFPE) tissue is challenging due to degradation of DNA and presence of PCR inhibitors in these samples. We analyzed FFPE samples of 26 patients by panfungal PCR and compared the results to the composite diagnosis according to the European Organization for Research and Treatment of Cancer (EORTC) criteria. Additionally we ...
متن کاملLaboratory diagnosis of fungal infections
Selection of appropriate specimens for culture and microscopic examination is based on the results of clinical and radiographic examination and consideration of the most likely fungal pathogen that may cause such an infection. Specimens should be collected under aseptic conditions or after appropriate cleaning and decontamination of the collection site and rapidly transported to the clinical my...
