1.本研究旨在评估饲养期结束时肉鸡群中弯曲杆菌感染的流行率和定量，并确定相关的风险因素。2008年，在法国布列塔尼的121个肉鸡群中完成了关于饲养期的问卷调查，并采集了盲肠样品。在121个鸡群中的87个中分离出弯曲杆菌-患病率为71.9%（95%CI，63.7-80.1%），包括40.5%的空肠弯曲杆菌和29.8%的大肠弯曲杆菌。在阳性鸡群中，平均浓度为7.96 log（10）cfu/g，范围为3.15至10.32 log（10）cfu/g。各物种的平均浓度为：C. 7.57 log（10）cfu/g;空肠为8.44 log（10）cfu/g; coli.6.存在季节性效应，弯曲杆菌定殖的风险在6月、7月和8月增加（比值比（OR）=9.59，95%CI 1.15-79.75）。与弯曲杆菌定植风险较低相关的其他因素是饮用水酸化（OR=0.33，95% CI 0.13-0.86），饲养期开始时的抗生素治疗（OR=0.20，95% CI 0.07-0.55）和房屋周围的啮齿动物控制（OR=0.18，95% CI 0.03-0.95）。结果表明，卫生习惯和生物安全措施可以减少弯曲杆菌的定植。
1. A study was conducted to estimate the prevalence and quantification by species of Campylobacter infection in broiler flocks at the end of the rearing period and to identify associated risk factors.2. A questionnaire about the rearing period was completed and caecal samples were collected from 121 broiler flocks in Brittany, France, during 2008.3. Campylobacter was isolated in 87 out of 121 flocks - a prevalence of 71.9% (95% CI, 63.7-80.1%), including 40.5% of Campylobacter jejuni and 29.8% of Campylobacter coli.4. The average concentration, in positive flocks, was 7.96 log(10) cfu/g and ranged from 3.15 to 10.32 log(10) cfu/g.5. The average concentration by species was: 7.57 log(10) cfu/g for C. jejuni and 8.44 log(10) cfu/g for C. coli.6. There was a seasonal effect, with increased risk of Campylobacter colonisation in June, July and August (odds ratio (OR)=9.59, 95% CI 1.15-79.75).7. The other factors, associated with lower risk of Campylobacter colonisation, were the acidification of drinking water (OR=0.33, 95% CI 0.13-0.86), antibiotic treatment at the beginning of the rearing period (OR=0.20, 95% CI 0.07-0.55) and rodent control around the house (OR=0.18, 95% CI 0.03-0.95).8. The results show that hygiene practices and biosecurity measures could lead to a reduction in Campylobacter colonisation.
