Misidentification of Saprochaete clavata as Magnusiomyces capitatus in clinical isolates: utility of internal transcribed spacer sequencing and matrix-assisted laser desorption ionization-time of flight mass spectrometry and importance of reliable databases.

Saprochaete clavata and Magnusiomyces capitatus are human pathogens that are frequently mistaken for each other due to their similar phenotypes and erroneous or limited databases. Based on internal transcribed spacer (ITS) sequences, we propose species-specific carbon assimilation patterns and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) fingerprints that enable the identification of S. clavata, M.

[Laboratory diagnosis of mucormycosis].

Mucormycosis are deep infections caused by ubiquitous filamentous fungi of the order of Mucorales. The disease occurs mostly in immunocompromised, diabetic or solid organ transplant recipients. There are currently no specific diagnostic guidelines for mucormycosis.
