WHO Bacterial Priority Pathogens (2024)
The World Health Organization publishes a periodic priority list of antibiotic-resistant bacteria to guide research, surveillance, and stewardship efforts. QualiBact provides species-level genome assembly QC thresholds for most of the species named below — click through to see the recommended thresholds.

Critical priority
Acinetobacter baumannii
Enterobacterales
Mycobacterium tuberculosis
Tuberculosis is treated separately in the WHO TB programme; included here for completeness.
High priority
Salmonella enterica serotype Typhi
Typhi is a serotype of S. enterica; thresholds shown are for the species as a whole.
Shigella spp.
Shigella is phylogenetically nested within Escherichia coli; E. coli thresholds are the closest available proxy until Shigella-specific thresholds are added.
Enterococcus faecium
Pseudomonas aeruginosa
Non-typhoidal Salmonella
All S. enterica serotypes except Typhi.
