New Bacteriophages Members of the Family Specific for ST258.

Background: Carbapenem-resistant , particularly isolates classified as sequence-type 258 (ST258), are multidrug-resistant strains that are strongly associated with poor-prognosis nosocomial infections, as current therapeutic options are limited and ineffective. In recent years, phage therapy has emerged as a promising treatment option for these scenarios.

Methodology And Results: We report the isolation and characterization of three new phages against ST258 strains recovered from Machángara river wastewater.
