TABLE 2.
Comparison between the rates of resistance to three antimicrobial agents of C. jejuni strains acquired abroad and the rates of resistance of those acquired locally from 1999 to 2001
| Agent | Resistance ratea (%) of strains acquired:
|
P valueb | |
|---|---|---|---|
| Abroad (n = 74) | Locally (n = 109) | ||
| Erythromycin | 1 | 6 | 0.15 |
| Tetracycline | 55 | 58 | 0.87 |
| Ciprofloxacin | 66 | 9 | <0.00001 |
a
C. jejuni strains for which the erythromycin, tetracycline, and ciprofloxacin MICs were ≥8, ≥16, and ≥4 μg/ml, respectively, were reported to be resistant. One strain from each patient was tested.
b
Chi-square or Fisher's exact two-tailed test.
