Host range and lytic capability of phages AHP24, AHS24, AHP42 and AKS96.

aPT represents phage type of STEC O157:H7 strainsbSensitivities are grouped on the basis of multiplicity of infection (MOI: the lowest ratio of phage to bacteria that resulted in complete lysis of an overnight bacterial culture during 5 h of incubation with serial dilutions of the phage). +++: extremely susceptible (MOI –: non-susceptible (i.e., no lysis observed).cECOR collection represents standard reference strains of Escherichia coli[21].
