Subjects
Drug resistance, Salmonella entérica, bacterial, Microbial sensitivity tests
Abstract

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.

Abstract

Leptospirosis is a anthropozoonosis of occupational character, which has been clinically and serologically diagnosticated in the country. In the present study a population of 74 veterinarians from the Province of Ñuble were analyzed, 54 of them were the exposed group and the other 20 conformed the control group. For the diagnosis, the microscopie agglutination technique was used; a 7.41% of prevalence was obtained. The serovars found were icterohaemorrhagiae (5.5%) and pomona (1.8%) and the antibody titer varied within 1/50 to 1/100. There were no positive reactions in the control group., La leptospirosis es una antropozoonosis de carácter ocupacional, que ha sido diagnosticada clínica y serológicamente en el país. En el presente estudio se analizó una población de 74 médicos veterinarios de la provincia de Ñuble; 54 de ellos constituyeron el grupo expuesto y los 20 restantes formaron el grupo control. Para el diagnóstico se utilizó la técnica de aglutinación microscópica (MAT), obteniéndose una prevalencia de 7,4%. Los serovares encontrados fueron icterohaemorrhagiae y pomona con 5,6% y 1,8%, respectivamente y los títulos de anticuerpos variaron entre 1/50 a 1/100. En el grupo control no se pesquisaron reaccionantes positivos.
