Estimated parameters determined by logistic regression of temporal development of resistance in Acinetobacter spp. on integrated farm B1a
| Antimicrobial | Intercept (%) (95% confidence interval)b | Increase in odds per day (95% confidence interval)c |
|---|---|---|
| Chloramphenicol | 3.7 (0.98-11) | 1.04 (1.02-1.07) |
| Ciprofloxacin | 2.4 (0.62-7.1) | 1.07 (1.04-1.10) |
| Erythromycin | 2.9 (0.75-9.0) | 1.05 (1.03-1.07) |
| Oxytetracycline | 1.9 (0.37-6.6) | 1.10 (1.07-1.15) |
| Sulfamethoxazole | 0.9 (0.12-3.7) | 1.11 (1.08-1.17) |
| Trimethoprim | 4.6 (1.0-15) | 1.03 (1.01-1.05) |
a
See Fig. 2.
b
The intercept is an estimate of the background (or zero time) level of resistance.
c
The increase in odds per day is the factor that the odds of finding a resistant isolate is multiplied by per day.
