pathogenicity phenotype restored pathogenicity 2025-07-14T13:24:34Z pathogen_host_interaction_phenotype qc_extension_only changh A phenotype where the ability of a pathogen to produce an infectious disease in another organism is restored (pathogenicity was present, then absent, and now present). For use in the annotation extension infective ability. Can only apply to changes in the pathogen. Note that this ability to cause pathogenicity is a feature of the pathogen. Therefore restoration of pathogenicity should never be dependent on changes to the host genotype, only on changes to the pathogen genotype. If you are annotating changes in disease presence or absence dependent on the changes to the host consider increased/decreased virulence phenotypes.
