众所周知，沙门氏菌是由动物携带的，并且在大多数情况下是无症状的宿主。监测工作重点关注农业和食物链上的污染点作为人类感染的主要来源；然而，人们很少关注野生动物在沙门氏菌传播中的贡献以及人为来源对抗生素抗性沙门氏菌血清型在野生动物物种中循环的影响。对每年 11 月至 3 月期间在欧洲和北美栖息的大型鸦科动物进行了一项有目的的调查。来自 11 个国家的 2778 份乌鸦粪便样本提交了沙门氏菌检测。文化测试。对推定阳性分离株进一步进行血清分型、药敏测试并分析抗生素抗性基因。总体而言，1.40% (39/2778) (CI=1.01, 1.90) 的样本呈沙门氏菌阳性。肠炎沙门氏菌是最流行的血清型，其次是婴儿沙门氏菌、蒙得维的亚沙门氏菌和鼠伤寒沙门氏菌。欧洲与北美回收的沙门氏菌比例没有显着差异（P>0.05）。一个地点内血清型变异最大的是美国堪萨斯州，发现了五种不同的血清型。欧洲地区更有可能产生对一种以上抗生素具有耐药性的沙门氏菌（OR 71.5，P
It is well understood that Salmonella is carried by animals and in majority of cases as asymptomatic hosts. Surveillance efforts have focused on the role of agriculture and contamination points along the food chain as the main source of human infection; however, very little attention has been paid to the contribution of wildlife in the dissemination of Salmonella and what effect anthropogenic sources have on the circulation of antibiotic resistant Salmonella serovars in wildlife species. A purposive survey was taken of large corvids roosting yearly between November and March in Europe and North America. Two thousand and seven hundred and seventy-eight corvid faecal specimens from 11 countries were submitted for Salmonella spp. culture testing. Presumptive positive isolates were further serotyped, susceptibility tested and analysed for antibiotic resistance genes. Overall, 1.40% (39/2778) (CI=1.01, 1.90) of samples were positive for Salmonella spp. Salmonella Enteritidis was the most prevalent serovar followed by S.Infantis, S.Montevideo and S.Typhimurium. No significant difference (P>0.05) was found in the proportion of Salmonella recovered in Europe versus North America. The most variability of serovars within a site was in Kansas, USA with five different serovars recovered. European sites were significantly more likely to yield Salmonella resistant to more than one antibiotic (OR 71.5, P
