Abstract
Identification of mycobacteria is crucial for clinical management of patients. The new MBT Mycobacteria kit from the Easy MycoEx protocol (Bruker) is used for the identification of mycobacteria by MALDI Biotyper. The Easy MycoEx protocol was compared to the MycoEx protocol (1) for identification of various mycobacterial isolates collected from samples in 2021, (2) for prospective identification on primary culture during 2 periods. For 44 isolates in MGIT broth, identification rates were high and similar for both protocols (98% vs 95% at cut-off 1.6 and 91% vs 82% at cut-off 1.8). For 42 mycobacteria on Coletsos agar, identification rates were 88% versus 90% at cut-off 1.6 and 76% for both protocols at cut-off 1.8. For slow-growing mycobacteria in MGIT, reproducibility of deposit results was superior with Easy MycoEx. No difference of score was observed between 2 protocols performed on primary culture. Clinical laboratories can easily implement the Easy MycoEx protocol.

Abstract
We report 3 cases of successful treatment of Microascus spp. bronchopulmonary infection in a multiple-traumatized patient and 2 lung transplant recipients in France. We emphasize the promising use of olorofim antifungal therapy in a rising context of intrinsically less-susceptible respiratory infections caused by mold.

Abstract
Rhinocladiella mackenziei cerebral phaeohyphomycosis is a rare severe disease that has been typically described in the Middle East. Here, we report 2 cases of R. mackenziei cerebral phaeohyphomycosis in patients from Morocco, diagnosed and treated in France, and raise a concern about the ever-going extension of the area at risk for this devastating invasive fungal infection.

Abstract
Identification of moulds is crucial for the clinical management of patients. The goal of this study was to evaluate the new ID-FUNGI plate (IDFP) for the identification of moulds by MALDI Biotyper. IDFP was compared with Sabouraud with gentamicin and chloramphenicol plate (SAB) for the identification of 80 moulds from respiratory samples and eight reference strains. With the direct transfer method, species identification rose from 6% with SAB to 68% with IDFP using score cut-off 2 and from 20 to 75% using cut-off 1.7 (p < 0.001). Our study highlights that the new IDFP improves mycological diagnostic and workflow in laboratories.
