减少弯曲菌病的发生是一个高度优先的食品安全问题，因为近年来它已成为欧盟最常见的人畜共患病。畜牧场特别受关注，因为牛、猪和家禽是弯曲杆菌属的常见宿主。农场环境为一些据报道携带嗜热弯曲杆菌属的鸟类提供了有吸引力的觅食和繁殖栖息地。我们研究了弯曲杆菌属。丹麦 12 个农场的 52 种野生鸟类的携带率在冬季和夏季进行采样，以便根据生态协会研究影响野生鸟类流行的因素。总共对 1607 个野鸟泄殖腔拭子样本和 386 个牲畜粪便样本进行了弯曲杆菌属培养。根据北欧食品分析委员会方法 NMKL 119。最高的弯曲杆菌属。 178 只画眉鸟中有 110 只 (61.8%) 患病，其中大多数是普通黑鸟 (Turdus merula)，616 只麻雀中有 131 只 (21.3%) 患病，由家麻雀 (Passer Domesticus) 和欧亚树麻雀 (Passer montanus) 组成。一般来说，以动物或动植物混合饲料为食、在地面和牲畜圈附近的植被上觅食的鸟类更有可能携带弯曲杆菌属。在夏季 (P < 0.001) 和冬季 (P < 0.001) 中，鸟类在远离农场或空中觅食的情况下。未发现年龄、脂肪评分、性别和迁移范围与弯曲杆菌属相关。运输。野生鸟类中空肠弯曲菌的患病率（%）与牛场（R2 = 0.92）和家禽养殖场（R2 = 0.54）粪便中空肠弯曲菌的比例（%）之间存在相关性，野生鸟类中大肠杆菌的患病率（%）与养猪场粪便中大肠杆菌的比例（%）之间存在相关性（R2 = 0.62）。野生鸟类的生态行会影响弯曲杆菌属的流行。通过鸟类的行为模式。更具体地说，吃动物或动植物混合食物并在靠近牲畜的地面上觅食的野生鸟类更有可能携带弯曲杆菌属。比那些在更远的地方觅食或在空中狩猎的人更重要。这些发现表明野生鸟类可能在维持弯曲杆菌属的流行病学中发挥作用。在农场。
Reducing the occurrence of campylobacteriosis is a food safety issue of high priority, as in recent years it has been the most commonly reported zoonosis in the EU. Livestock farms are of particular interest, since cattle, swine and poultry are common reservoirs of Campylobacter spp. The farm environment provides attractive foraging and breeding habitats for some bird species reported to carry thermophilic Campylobacter spp. We investigated the Campylobacter spp. carriage rates in 52 wild bird species present on 12 Danish farms, sampled during a winter and a summer season, in order to study the factors influencing the prevalence in wild birds according to their ecological guild. In total, 1607 individual wild bird cloacal swab samples and 386 livestock manure samples were cultured for Campylobacter spp. according to the Nordic Committee on Food Analysis method NMKL 119. The highest Campylobacter spp. prevalence was seen in 110 out of 178 thrushes (61.8 %), of which the majority were Common Blackbird (Turdus merula), and in 131 out of 616 sparrows (21.3 %), a guild made up of House Sparrow (Passer domesticus) and Eurasian Tree Sparrow (Passer montanus). In general, birds feeding on a diet of animal or mixed animal and vegetable origin, foraging on the ground and vegetation in close proximity to livestock stables were more likely to carry Campylobacter spp. in both summer (P < 0.001) and winter (P < 0.001) than birds foraging further away from the farm or in the air. Age, fat score, gender, and migration range were not found to be associated with Campylobacter spp. carriage. A correlation was found between the prevalence (%) of C. jejuni in wild birds and the proportions (%) of C. jejuni in both manure on cattle farms (R2 = 0.92) and poultry farms (R2 = 0.54), and between the prevalence (%) of C. coli in wild birds and the proportions (%) of C. coli in manure on pig farms (R2 = 0.62). The ecological guild of wild birds influences the prevalence of Campylobacter spp. through the behavioural patterns of the birds. More specifically, wild birds eating food of animal or mixed animal and vegetable origin and foraging on the ground close to livestock were more likely to carry Campylobacter spp. than those foraging further away or hunting in the air. These findings suggest that wild birds may play a role in sustaining the epidemiology of Campylobacter spp. on farms.
