Abstract
The gene of protein phosphatase Z1 (CaPPZ1) that codes a fungus specific regulatory enzyme was investigated in Candida albicans. After cloning and sequencing CaPPZ1 we revealed the heterozygous nature of the ATCC 10231 reference strain, and identified two new alleles termed CaPPZ1-2 and CaPPZ1-3. The genetic polymorphism in CaPPZ1 was extended by finding a fourth allele CaPPZ1-4 in a clinical isolate. Single nucleotide replacements and short in/del mutations were identified in the gene, some of which resulted in amino acid changes in the protein. The analysis of the hypervariable 3'-noncoding gene region in 27 DNA sequences obtained from reference strains and clinical samples confirmed the presence of four distinct DNA sequence-groups that correspond to the four main alleles of CaPPZ1. In addition to the allelic combinations, we detected individual mutations elevating genetic variability of the opportunistic pathogen. We utilized the hypervariable gene region for genotyping C. albicans in clinical isolates by sequencing the cloned amplified region, by direct sequencing of the PCR products, or by RFLP analysis. The comparison of the genotypes of the strains originating from different body parts of the same patient proved to be useful in delineating the origin of the infection.

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
