Oct 1, 2025In 2025-10, two high-impact features were delivered in the theiagen/public_health_bioinformatics project, advancing AMR detection and phylogenetic analysis within TheiaEuk workflows. The ChroQueTas AMR detection integration now identifies AMR mutations and associated fungicide resistance by leveraging FungAMR, and is available as a standalone workflow and integrated into TheiaEuk pipelines for Illumina and ONT data. The SNP_sites task was added to the Core_Gene_SNP workflow to extract polymorphic sites from alignments, with documentation and workflow definitions updated to improve phylogenetic trees and SNP distance matrices. These changes improve surveillance capabilities, shorten analysis cycles, and provide end-to-end AMR and phylogenetic insights for public health decisions.

May 1, 2025May 2025 monthly summary for theiagen/public_health_bioinformatics: Focused on reliability and data integrity for the MUMmer ANI workflow. Delivered a targeted bug fix to gracefully handle edge cases where ANI results are non-informative (all zeros) or contain only a header, preventing misinterpretation and downstream errors. The change improves user-facing output when genetic divergence is high and reduces confusion in reported metrics.
