Cecal contents (16 samples/each flock) of broilers derived from 212 flocks were investigated for colonization of Campylobacter from 1995 to 1999 in the southern part of Japan, and the isolates were tested for antimicrobial susceptibilities. C. jejuni-positive flocks numbered 42 (19.8%) and C. coli-positive ones 26 (12.3%); Campylobacter spp. were recovered from 68 flocks (32.1%) in total. MICs of ampicillin, erythromycin (EM), tetracycline, nalidixic acid (NA), norfloxacin (NFLX), and ofloxacin (OFLX) to these 68 Campylobacter isolates were determined. Quinolone-resistant Campylobacter isolates numbered 22 (32.4%). All the isolates except one were cross-resistant to NA, OFLX, and NFLX. A high frequency of quinolone-resistance was found in both C. jejuni and C. coli, whereas a high level of EM-resistance was found in only C. coli strains. All C. jejuni isolates were sensitive to EM.
1995年至1999年期间，对日本南部212个鸡群的肉鸡盲肠内容物（每个鸡群16个样本）进行了弯曲杆菌定植情况调查，并对分离株进行了药敏试验。空肠弯曲菌阳性鸡群有42个（19.8%），结肠弯曲菌阳性鸡群有26个（12.3%）；总共从68个鸡群（32.1%）中分离出弯曲杆菌属。测定了氨苄西林、红霉素（EM）、四环素、萘啶酸（NA）、诺氟沙星（NFLX）和氧氟沙星（OFLX）对这68株弯曲杆菌分离株的最低抑菌浓度（MIC）。耐喹诺酮类弯曲杆菌分离株有22个（32.4%）。除1株外，所有分离株对NA、OFLX和NFLX均呈交叉耐药。空肠弯曲菌和结肠弯曲菌中均发现喹诺酮耐药的高频率，而仅在结肠弯曲菌菌株中发现高水平的红霉素耐药。所有空肠弯曲菌分离株对红霉素敏感。
