a
With the exception of C. coli 6067 (isolated from water in the turkey house), bacteria were obtained as described previously (27) from fecal samples from the indicated animal source.
b
Antimicrobial susceptibility profiles were determined as described previously (10) for a panel of antibiotics, including tetracycline (T), streptomycin (S), erythromycin (E), kanamycin (K), and (fluoro)quinolones (nalidixic acid and ciprofloxacin [Q]).
c
Sequence types (STs) were determined by multilocus sequence typing as described previously (17). ND, not determined.
