弯曲杆菌病是欧盟最常报告的人畜共患病。最近的一份报告指出，50%至80%的人类弯曲杆菌病病例可归因于肉鸡作为宿主。本研究旨在调查弯曲杆菌属的存在与细菌感染之间的关系。在挪威肉鸡群和有关的气候和农场环境的因素。2002年至2007年期间，来自623个不同农场的18,488个肉鸡群的数据被纳入研究。进行逻辑回归分析，其中弯曲杆菌属。屠宰时肉鸡群的状态被定义为因变量，农场被建模为随机效应。发现以下因素会增加肉鸡群检测弯曲杆菌属阳性的概率：饲养期间日平均气温高于6摄氏度、私人供水、2公里范围内存在其他畜牧场、4公里范围内存在其他肉鸡养殖场且鸡群弯曲杆菌呈阳性。屠宰前30天内，屠宰前11-30天强降雨，地区和年份。日平均气温低于0度的概率降低。这项研究强调了农场环境和气候对弯曲杆菌发生的重要性。在肉鸡群中。农场环境可能是弯曲杆菌属的一部分。进入肉鸡群和肉鸡群之间的通道，其中农家庭院径流和进入鸡舍的人或苍蝇可能构成运输生物体的载体。苍蝇活动是温度驱动的，苍蝇可能是弯曲杆菌属风险增加的部分解释。与研究中证明的温度升高有关。(C)2012爱思唯尔有限公司版权所有。
Campylobacteriosis is the most frequently reported zoonosis in the EU. A recent report states that between 50% and 80% of the human campylobacteriosis cases could be attributed to broiler as a reservoir. The current study was conducted to investigate associations between the presence of Campylobacter spp. in Norwegian broiler flocks and factors related to the climate and the farm environment. Data from 18,488 broiler flocks from 623 different farms during 2002-2007 were included in the study. A logistic regression analysis was conducted where Campylobacter spp. status of a broiler flock at the time of slaughter was defined as the dependent variable and farm was modelled as a random effect. The following factors were found to increase the probability for a broiler flock to test positive for Campylobacter spp.: daily mean temperature,above 6 degrees C during the rearing period, private water supply, presence of other livestock farms within a distance of 2 km, presence of other broiler farms within a distance of 4 km with flocks positive for Campylobacter spp. within 30 days prior to slaughter, heavy rainfall 11-30 days prior to slaughter, region and year. Daily mean temperature below 0 degrees reduced the probability. The study emphasises the importance of the farm environment and the climate for the occurrence of Campylobacter spp. in broiler flocks. The farm environment is probably a part of the Campylobacter spp. pathway into and between broiler flocks where farmyard run-off and humans or flies entering the houses might constitute vehicles transporting the organism. Fly activity is temperature-driven and flies might be a part of the explanation of the increased risk for Campylobacter spp. related to increased temperature demonstrated in the study.
