Resumen
Background: Bacterial resistance to one or more antimicrobiak is worrisome. Aim: To determine the susceptibility to antimicrobials of Salmonella entérica isolates from animáis and food, from the Laboratory ofVeterinary Microbiology at the University of Concepción. Material andMethods: 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 observ.ed in20.5% ofthestrains tested. The mostcommon 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 afollow-up study ofthispathogen.
