title: [Antimicrobial susceptibility of animal and food isolates of Salmonella enterica].
abstract: BACKGROUND
  Bacterial resistance to one or more antimicrobiak is worrisome.
  
  
  OBJECTIVE
  To determine the susceptibility to antimicrobials of Salmonella entérica isolates from animáis and food, from the Laboratory of Veterinary Microbiology at the University of Concepción.
  
  
  METHODS
  The samples were isolated according to traditional microbiological methods standardized protocols. Resistance was determined by the Kirby-Bauer method and minimal inhibitory concentration (MIC), following Clinical and Laboratory Standards Institute recommendations (2008).
  
  
  RESULTS
  Nine serotypes were identified among the 68 isolates. Strains were resistant to one or more antibiotics and 11 patterns of resistance were identified. Multidrug resistance (MDR) was observed in 20.5% of the strains tested. The most common was Oxytetracycline resistance (69.1%). Infood, the predominant serotype was S. Derby (2.9%) and S. Senftenberg (2.9%), which is commonly found infood intended for animal consumption. In samples of animal origin, the predominant serotypes were S. infantis (33.8%) and S. Group E (3.9;-;-) (23.5%).
  
  
  CONCLUSIONS
  The frequeney of resistance found and the impending risk that these strains could reach humans through the food chain, should prompt a follow-up study of this pathogen.
