Der volle Inhalt der QuelleIn recent years, the cryptic species concept has revolutionized the Aspergillus genus taxonomy. Henceforth, dozens of species could be found in human samples, with an increasing incidence. However, as their identification remains a challenge, few is known regarding their pathogenicity or their antifungal susceptibility. The recent development of the MSI web application dedicated to the microorganism’s identification from their mass spectra, has improved these “new” species identification in numerous centers. The collaboration with this network of users allowed us to collect and study a large collection of cryptic isolates (390 isolates from 69 species and 13 sections), combining an accurate DNA sequence-based identification, the antifungal susceptibility testing by reference method and the clinical involvement. We brought evidence for species-dependent antifungal resistance patterns. We also highlighted the extent of species diversity involved in human disease, including some species never described, and the species-dependent pathogenicity patterns for some species. Thus, this work improved the knowledge on Aspergillus cryptic species and underline the importance of their accurate identification in clinical practice. The new version 2 of the MSI application, upgraded during this study, stand for an easy and powerful tool for this

Der volle Inhalt der QuelleThe yellow-legged gull is endemic in the French Mediterranean area. Their gut mycobiota has never been studied. This work aimed to describe their role in the spreading of potentially human pathogenic fungi with antifungal resistance. Therefore, we sampled 177 yellow-legged gull’s faecal samples in five sites along the Mediterranean littoral South of France; La Grande-Motte, Palavas-les-Flots, Pierre-Blanche, Frioul and Riou archipelagos. We identified seventeen yeast species; the most frequent were Candida krusei, Galactomyces geotrichum, C. glabrata, C. albicans and Saccharomyces cerevisiae. The frequency of the anthropic yeast species C. glabrata and C. albicans increased with the synanthropy of the gull’s colonies and antifungal resistance was found in each of the five most frequent yeast species. We further analyzed the airborne filamentous fungi species isolated from the same sample cultures. We identified 35 filamentous fungi species in 16 genera including 35 species. Both fungal diversity and abundance were low in urban area when compared to suburban ecocline or environments that were little affected by anthropogenic impact and particular fungal species were clearly associated with distinct environments. Finally, we analyzed the population genetic of the human pathogenic yeast C. glabrata, which were isolated from gulls (111 isolates) and from patients (79 isolates) in Nimes, Montpellier and Marseille hospitals, via MLVA analysis. We found that the C. glabrata populations isolated from gulls or humans shared a similar genetic diversity. Antifungal-resistant C. glabrata isolates were evenly distributed in both gull and human populations
