Antimicrobial resistance (AMR) is one of the most important threats of the 21 st century. Wild birds have been described as reservoirs of AMR in different bacterial species, such as Salmonella spp. Privation of food, climate change and overpopulation have forced many wild species to modify their feeding habits, attending urban areas. In this context, the aim of this study was to study Salmonella presence, as well as related AMR in urban birds that inhabit the city and its surroundings. A total of 300 urban birds were sampled for Salmonella detection according to the ISO 6579-1:2017 (Annex D) recommendations, and serotyping was carried out according to the White-Kauffman-Le Minor scheme. Antimicrobial susceptibility was tested following 2013/652/EU Decision guides. Wild birds analysed were positive for Salmonella in 12.3 % of cases, with white storks fed in landfills as the most Salmonella prevalent species (p < 0.05). The most common serovars isolated were zoonotic (S. Enteritidis, S. Typhimurium and S. Typhimurium monophasic variant). From Salmonella isolated strains, 40.5 % were resistant to the most prevalent AMRs found in urban birds were ciprofloxacin (36.4 %), nalidixic acid (36.4 %) and colistin (27.3 %). The scientific community, public administration and population in general should work together to control antimicrobial administration and drug waste management in order to decrease the development and spread of AMR.

抗菌素耐药性（AMR）是21世纪最重要的威胁之一。野生鸟类已被描述为不同细菌物种（如沙门氏菌属）中的AMR贮藏库。食物的私有化，气候变化和人口过剩迫使许多野生物种改变其进食习惯，进入城市地区。在这种情况下，本研究的目的是研究居住在城市及其周边地区的城市鸟类中沙门氏菌的存在以及相关的AMR。总共对300只城市鸟类进行了沙门氏菌采样根据ISO 6579-1：2017（附件D）建议进行检测，并根据White-Kauffman-Le Minor计划进行血清分型。遵循2013/652 / EU决策指南测试了抗生素敏感性。经分析的野生鸟类沙门氏菌呈阳性，占12.3％，以填埋场喂养的白鹳为沙门氏菌最常见物种（p <0.05）。分离出的最常见的血清型是人畜共患（S.肠炎，S.鼠伤寒沙门氏菌和S.鼠伤寒沙门氏菌单相变体）。从沙门氏菌分离出的菌株对城市鸟类中发现的最普遍的AMR耐药率为40.5％，其中环丙沙星（36.4％），萘啶酸（36.4％）和粘菌素（27.3％）。科学界，公共行政部门和一般民众应共同努力控制抗菌药物管理和药物废物管理，以减少抗菌药物耐药的发展和传播。
