Relationship between Phage Lytic Spectra and Sequence Types in Extended-Spectrum β-Lactamase-Producing Escherichia coli Isolated in Japan.

The lytic spectrum of phages is usually limited to only a few strains of the same bacterial species that can lyse. In clinical molecular epidemiology, bacterial strains are commonly classified into sequence types (STs) using the multilocus sequence typing (MLST) approach. The aim of this study was to determine the association between the phage lytic spectrum and STs.
