Rapid diagnosis of azole-resistant aspergillosis by direct PCR using tissue specimens.
نویسندگان
چکیده
We report the use of PCR techniques on a formalin-fixed and paraffin-embedded tissue specimen for direct detection of one dominant azole resistance mechanism in a case of disseminated invasive aspergillosis. Rapid detection of mutations associated with azole resistance directly in tissue significantly reduces diagnostic delay.

Molecular Detection of Azole-Resistant Aspergillus fumigatus in Clinical Samples
Aspergillus diseases are often caused by Aspergillus fumigatus. Azoles are the mainstay of therapy, but the management of aspergillosis is hampered by the emergence of azole resistance. Rapid detection of azole resistance might benefit treatment outcome by early treatment modifications. However, the yield of fungal culture in invasive aspergillosis is low and susceptibility testing requires sev...
متن کاملComparison of Polymerase Chain Reaction, Ziehl-Neelsen Staining and Histopathologic Findings in Formalin-fixed, Paraffin-Embedded Tissue Specimens for Diagnosis of Tuberculosis
Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world´s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study was to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of ...
متن کاملEmerging aspergillosis by azole-resistant Aspergillus fumigatus at an intensive care unit in the Netherlands, 2010 to 2013
The prevalence of invasive aspergillosis (IA) at the intensive care unit (ICU) is unknown and difficult to assess since IA also develops in patients lacking specific host factors. In the Netherlands, increasing azole-resistance in Aspergillus fumigatus complicates treatment of patients with IA. The aim of this study was to determine the prevalence of IA by azole-resistant A. fumigatus at the IC...
متن کاملDirect Molecular Diagnosis of Aspergillosis and CYP51A Profiling from Respiratory Samples of French Patients
BACKGROUND Microbiological diagnosis of aspergillosis and triazole resistance is limited by poor culture yield. To better estimate this shortcoming, we compared culture and molecular detection of A. fumigatus in respiratory samples from French patients at risk for aspergillosis. METHODS A total of 97 respiratory samples including bronchoalveolar lavages (BAL), bronchial aspirates (BA), trache...

Background and Aim: Aspergillosis are the most prevalent cause of the respiratory infections. These fungi show invasive aspergillosis(IA) in immunocompromised patients. The number of immunocompromised patients are increasing due to immunodisorder illnesses, grafts and immunosuppressor drugs, so, rapid identification methods are very important. The aim of this study was to detect the Aspergillus...
