Summary

Story summary

A large-scale genetic study identified five Escherichia coli capsule types responsible for 70% of Europe’s multidrug-resistant bloodstream infections.
Researchers from the Wellcome Sanger Institute and the University of Oslo analyzed 18,000 genomes and identified 90 capsule types, of which 69 were undocumented.
Findings show regional differences and underscore the need for standardized global data collection, while the work supports vaccines, treatments, and a resistance database.
