aUndetermined isolates were hippurate-negative Campylobacter that could not be further speciated with available polymerase chain reaction primers.
bFor azithromycin and gentamicin, only 1,336 isolates were tested.
cComparison of proportion of resistant C. coli to resistant C. jejuni was statistically significant for ciprofloxacin and nalidixic acid but not tetracycline (p < 0.01)
