Our objective was to identify the risk factors for Campylobacter infection in Senegalese broiler flocks. Seventy broiler farms were studied around Dakar from January 2000 to December 2001 around Dakar. A questionnaire was administered to the farmers, and samples of fresh droppings were taken to assess the flocks' Campylobacter status. About 63% of the flocks were infected by Campylobacter spp.; Campylobacter jejuni was the most-prevalent species (P < 0.05). An elevated risk of Campylobacter infection was associated with other animals (mainly laying hens, cattle and sheep) being bred in the farm, the farm staff not wearing their work clothing exclusively in the poultry houses, uncemented poultry-house floors and the use of cartons that transport chicks from the hatchery to the farm as feed plates (rather than specifically designed feed plates). Alternatively, thorough cleaning and disinfection of poultry-house surroundings and manure disposal outside the farm were associated with decreased flock risk.
我们的目标是确定塞内加尔肉鸡群弯曲杆菌感染的风险因素。2000年1月至2001年12月期间，在达喀尔周边地区对70个肉鸡养殖场进行了研究。向养殖户发放了调查问卷，并采集新鲜粪便样本以评估鸡群的弯曲杆菌感染状况。约63%的鸡群感染了弯曲杆菌属；空肠弯曲杆菌是最常见的菌种（P < 0.05）。弯曲杆菌感染风险升高与养殖场饲养其他动物（主要是蛋鸡、牛和羊）、养殖场工作人员未在禽舍专门穿着工作服、禽舍地面未硬化以及使用从孵化场运送雏鸡到养殖场的纸箱作为饲料盘（而非专门设计的饲料盘）有关。另外，禽舍周边的彻底清洁和消毒以及养殖场外粪便的处理与鸡群感染风险降低有关。
