is one of the main causes of gastrointestinal disease worldwide. Wild birds are capable of harboring a variety of serovars, which could have an important role in the epidemiology of salmonellosis in humans and production animals. We tested 519 fecal samples from raptors and aquatic birds from different regions of central (three rehabilitation centers for wildlife and the coastal area) and southern areas of Chile for . All samples were obtained in 2015 and 2017, covering all four seasons. was isolated from 12 of the 519 samples (2%) analyzed, from two carnivorous birds, four birds with generalist habits, and six waterfowl. Among the isolates obtained, one showed resistance to gentamicin, and one showed a multidrug-resistance phenotype, with resistance to ampicillin, ceftriaxone, ciprofloxacin, chloramphenicol, streptomycin, gentamicin, kanamycin, trimethoprim-sulfamethoxazole, and tetracycline. These results demonstrated the importance of characterizing in wild birds because previous studies have shown genetic and phenotypic evidence suggesting interspecies transmission of that is resistant to antimicrobials between humans and wild and domestic birds.
是世界范围内胃肠道疾病的主要病因之一。野生鸟类能够携带多种血清型，这可能在人类和生产动物中沙门氏菌病的流行病学中发挥重要作用。我们检测了来自智利中部（三个野生动物康复中心和沿海地区）和南部不同地区的 519 份猛禽和水鸟的粪便样本，以检测 。所有样本均于 2015 年和 2017 年获得，涵盖四季。从分析的 519 个样本中的 12 个（2%）中分离出了 ，来自两种肉食性鸟类、四种具有广食性习惯的鸟类和六种水禽。在所获得的分离株中，一株对庆大霉素表现出耐药性，一株表现出多药耐药表型，对氨苄西林、头孢曲松、环丙沙星、氯霉素、链霉素、庆大霉素、卡那霉素、复方磺胺甲噁唑和四环素均有耐药性。这些结果表明，对野生鸟类中的 进行特征分析非常重要，因为先前的研究表明，在人类和野生及家养鸟类之间存在对多种抗生素耐药的 具有遗传和表型证据，表明其存在种间传播。
