摘要

To determine the prevalence of the drug resistance in Escherichia coli (E. coli) in poultry in Taiwan, 575 field isolates collected between 1999 and 2000 were examined. Among them 495 isolates originated from chickens and 80 isolates from ducks. The susceptibility of these E. coli strains against 28 anti-microbial drugs was evaluated by the agar disk diffusion (Bauer-Kirby) test. Most of the isolates were multi-drug resistance. The inhibitory activity in decreasing order was florfenicol (81 .5%), ceftriaxone (78.5%), colistin (70.9%), polymyxin B (65.0%) and amikacin 58.8%). On the other hands, the resistance of the isolates test against tetracycline, doxycycline nalidixic acid, sulfamethoxazole, sufamethoxazole + trimethoprim and josamicin + trimethoprim exceeded 90%. The resistance rates of chicken E. coli isolates against 11 antimicrobial drugs were significant higher than that of duck isolates. (P＜0.05) Only the resistance rates against two drugs (amikacin and colistin) in duck isolates were higher than chicken isolates. It seems that the drug resistance was milder in duck isolates than in chicken isolates.
