Abstract
The Cryptococcus species complex consists of two species, Cryptococcus neoformans and Cryptococcus gattii, which cause systemic infections in both immunocompromised and immunocompetent patients. Both species have a bipolar mating system, with mating type (MAT) alpha being predominant in clinical and environmental isolates. The strains of the Cryptococcus species complex have been divided into eight major molecular types, which show differences in epidemiology, biology and pathogenicity. In this study, two PCR-RFLP analyses, based on the CAP1 and GEF1 genes, which are both located at the MAT locus, were developed for simultaneous identification of the molecular and mating types of isolates of the Cryptococcus species complex. The molecular and mating types of all 144 cryptococcal isolates, including rare subtypes, were successfully determined by both PCR-RFLP approaches. Pattern analysis of the AD hybrids revealed that the serotype A MATa allele in strains of AaDalpha derived from genotype VNB, whereas the serotype A MATalpha allele among strains of AalphaDa and AalphaDalpha derived from molecular type VNI.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
