in Raptors and Aquatic Wild Birds in Chile.

Abstract

is one of the main causes of gastrointestinal disease worldwide. Wild birds are capable of harboring a variety ofserovars, 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 characterizingin wild birds because previous studies have shown genetic and phenotypic evidence suggesting interspecies transmission ofthat is resistant to antimicrobials between humans and wild and domestic birds.
