Co-evolved Phages Show Promise Against Drug-Resistant Klebsiella

11/23/2025

Summary

Story summary

Researchers coevolved phages Ace and APV with 59 Klebsiella pneumoniae clinical isolates over 30 days.
The evolved phages showed improved host range and growth suppression against multidrug-resistant (MDR) and extensively drug-resistant (XDR) isolates.
Of 59 isolates, 20 were susceptible to antibiotics; 39 carried resistance genes, including 5 Carbapenem-Resistant Enterobacteriaceae.
Statistical analysis showed significant suppression in 75% of cases, suggesting coevolution may boost phage effectiveness against antibiotic-resistant Klebsiella in the USA.
