Abstract

fetched live from OpenAlex

Cryptococcus neoformans is an opportunistic fungal pathogen that heads the Fungal Priority Pathogen List published by the World Health Organization (WHO) in 2022. This pathogen is a primary cause of death for immunocompromised individuals (e.g., those with HIV/AIDS, the elderly, immunotherapy recipients), causing approximately 118,000 deaths yearly worldwide. C. neoformans relies on virulence factors that include a polysaccharide capsule, melanin, extracellular enzymes, and thermotolerance to initiate and sustain host infection. Additionally, similar to other fungal pathogens (e.g., Candida albicans), C. neoformans may develop a biofilm organization linked to more persistent cryptococcal infections. Cryptococcal biofilms are highlighted in cases of cryptococcal meningitis, in which biofilm-like structures form that are highly resistant to host immune response and to antifungal therapies. In this regard, fungal biofilm formation has become an important area of study as a means to improve our understanding of the mechanisms regulating biofilm formation and infection and to advance the discovery of antibiofilm therapeutics. To assess biofilm properties and compare across treatments, quantification and evaluation of cell viability are important. Herein, we describe a standardized method to establish a cryptococcal biofilm and quantify total biomass and cell viability. © 2025 The Author(s).

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
