This study compared two advanced technologies for identifying dangerous fungi in clinical samples. The MALDI Biotyper FFLv4.0 system identified about 96% of fungi correctly when using liquid culture samples, outperforming the MSI-2 database which identified about 78.5%. Both systems had difficulty with certain difficult-to-distinguish species, especially within Aspergillus and Fusarium groups, but performed well with Mucorales fungi. The findings suggest that continuous updating of these fungal identification libraries is essential for improving patient care.
