a

See Table S2 in the supplemental material for details on the 9 lysis groups. A phage lysis group was classified as lysing a reference strain if any phages in a given lysis group showed lysis on a given host strain.

b

Prevalence of phage susceptibility (P < 0.001) among reference strains that were classified into non-serotype 4 strains and serotype 4 strains.
