Heteroresistance refers to variability in antifungal sensitivity within microbial populations, impacting treatment outcomes. This study is the first to document voriconazole heteroresistance in Trichosporon asahii, finding significant levels across 62 clinical isolates in China. Results challenge the reliability of minimal inhibitory concentrations for treatment guidance of this emerging pathogen.

Invasive fungal infections (IFI) significantly impact global health, with Peru experiencing notable challenges in diagnosis and treatment. A comprehensive study of 54 healthcare centers revealed major disparities in access to advanced diagnostics and antifungals, particularly outside the capital. Addressing these gaps is crucial for effective IFI management and improved patient outcomes in Peru.

A recent study in mycology reveals that brain-dead organ donors exhibit an increased fungal burden in the gastrointestinal tract compared to donation after circulatory death donors. This disparity, marked by a higher prevalence of Candida spp., is linked to corticosteroid use and parenteral feeding in brain-dead donors, suggesting these practices may elevate invasive fungal infection risks for transplant recipients.

Furanosteroids, such as wortmannin and demethoxyviridin, are structurally distinct steroids with notable bioactivity. This study reports the heterologous expression of demethoxyviridin biosynthetic genes in Talaromyces wortmannii ATCC 26942, resulting in four potential novel furanosteroids. Two isolates exhibited antifungal activity against Aspergillus niger R330 and Candida albicans FIM709.

A new benchmark dataset, comprising 100 whole-genome sequenced Candida auris isolates, has been developed to validate echinocandin resistance detection tools. Utilizing MycoSNP-nf, the study identified FKS1 mutations in resistant strains, aiding in refining genomic approaches to combat rising echinocandin resistance in C. auris, critical for global healthcare systems.

Candida auris, a multidrug-resistant fungus, poses significant treatment challenges. This study reveals that sodium houttuyfonate (SH) and sodium new houttuyfonate (SNH), derivatives from Houttuynia cordata, effectively inhibit C. auris growth, adhesion, aggregation, and biofilm formation. These findings highlight SH and SNH's potential for novel antifungal therapies.

Phosphorylation, a biological process influencing molecular functions, is explored in PsiK kinase from Psilocybe cubensis. PsiK selectively phosphorylates phenols and benzenediols, extending beyond its native psilocin substrate. Active site mutations enhance substrate range and site-selectivity, with DESI-MS aiding rapid analysis. This work emphasizes PsiK's potential in mild, selective phosphorylation.

This research explores the integration of non-thermal technologies and microbial biotechnologies in sustainable wine production on the Iberian Peninsula. It highlights how High Hydrostatic Pressure, Ultrasounds, and other methods enhance phenol extraction and microbial control, reducing chemical usage. The region's unique setting offers a model for environmentally sustainable practices in global viticulture.

Aspergillus fumigatus, a major cause of invasive fungal infections, shows increased triazole resistance linked to the loss of spindle assembly checkpoint components SldA or SldB. This study reveals that these losses induce heteroresistance by fostering conidial populations with potential aneuploidy, specifically under ergosterol biosynthesis inhibition, highlighting new resistance mechanisms.

Single-atom nanozymes (SAzymes) are engineered enzyme mimics offering enhanced catalytic capabilities. This study introduces Ce-induced adaptive synergism, where a Ce atom activates Ni-Fe sites to enhance multi-enzymatic functions of Ce-MOF, showing potent antifungal effects against Fusarium solani and fostering beneficial microbial recovery, thereby supporting sustainable Panax ginseng cultivation.

Conidial germination initiates fungal colonization, leading to disease or symbiosis. This study compares Fusarium graminearum, a plant pathogen, and Metarhizium anisopliae, an endophyte, revealing distinct gene expression profiles. F. graminearum upregulates pathogenesis-related genes, while M. anisopliae enhances phytohormone pathways, elucidating divergent host interaction strategies.

Metagenomic next-generation sequencing (mNGS) offers a promising diagnostic advantage for detecting invasive pulmonary aspergillosis (IPA) in immunocompromised ICU patients. A study across six Chinese hospitals demonstrated mNGS's superior specificity and sensitivity over conventional tests, significantly reducing 28-day mortality rates through guided antibiotic adjustments, indicating improved patient outcomes.
