spp. and are foodborne pathogens of global importance. We assessed their risks and associated factors in a highly dynamic population of animals. Animal and environmental samples were collected from dairy cattle, sheep, camel and chickens at either the farms or the abattoirs. The pathogens were detected using a combination of bacterial enrichment culture and real-time polymerase chain reaction (PCR). Data on putative risk factors were collect and analysed for their significance of association with these pathogens. spp. were detected at higher proportions in sheep faeces and sheep carcasses in comparison to cattle faeces (odds ratio = 2.4 and 2.2, respectively). This pathogen was less common in milk or carcasses samples from cattle or chickens. Sheep and camel carcass samples were highly contaminated with spp. Faecal samples from cattle had the most diverse serovars of including S. Newport, S. Haifa, S. Kedougou, S. Kentucky, S. Mbandaka and S. Goettingen. Exotic serovars in sheep included S. Eastbourne, S. Chester and S. Kottnus. Serovars that were shed in camel faeces included S. Newport, S. Bovismorbificans and S. Infantis. In all sampled populations, detection of spp. was more likely during warmer months than cold months. was not common in the targeted populations and was detected at a rate of 2.4%, mainly from sheep carcasses. The study highlights the role of food animals as reservoirs of pathogens across boundaries since all feed are imported in that population from different parts of the world.
某些物种和……是具有全球重要性的食源性病原体。我们在一个高度动态的动物群体中评估了它们的风险及相关因素。在农场或屠宰场采集了奶牛、绵羊、骆驼和鸡的动物及环境样本。使用细菌富集培养和实时聚合酶链反应（PCR）相结合的方法检测病原体。收集了关于假定风险因素的数据，并分析了它们与这些病原体关联的显著性。与牛粪相比，在绵羊粪便和绵羊胴体中检测到某些物种的比例更高（优势比分别为2.4和2.2）。这种病原体在牛或鸡的牛奶或胴体样本中不太常见。绵羊和骆驼胴体样本被某些物种高度污染。牛粪样本中某些物种的血清型最为多样，包括纽波特沙门氏菌、海法沙门氏菌、凯杜古沙门氏菌、肯塔基沙门氏菌、班达卡沙门氏菌和哥廷根沙门氏菌。绵羊中的外来血清型包括伊斯特本沙门氏菌、切斯特沙门氏菌和科特努斯沙门氏菌。骆驼粪便中排出的血清型包括纽波特沙门氏菌、牛病沙门氏菌和婴儿沙门氏菌。在所有采样群体中，与寒冷月份相比，在温暖月份更有可能检测到某些物种。……在目标群体中不常见，检出率为2.4%，主要来自绵羊胴体。该研究突出了食用动物作为跨边界病原体宿主的作用，因为该群体中的所有饲料都从世界不同地区进口。 （注：原文中部分物种名称未完整给出，翻译时保留了英文“spp.”等）
