a
In the strain designations C indicates that the strain was obtained from a cloacal sample, and E indicates that the strain was obtained from an excreta sample.
b
Lytic activity with all 25 bacteriophage isolates in this study. S, sensitive to all bacteriophages; R, resistant to all bacteriophages; S2/R23, sensitive to 2 bacteriophages and resistant to 23 bacteriophages.
c
MRP determined by PFGE of Smal-digested genomic DNA phage type.
d
MLST (9) was carried out with selected strains.
e
UT, untypeable.
f
RDNC, reacts with phage but does not conform to a recognized phage type.
