Resumen
[ES] El trabajo se basó en investigar la carga microbiana con resistencia a los antibióticos que existe en las instalaciones de un matadero de conejos. El estudio consistió en muestrear las diferentes zonas del matadero con el objetivo de obtener muestras representativas. Una vez hecho el muestreo, se cultivaron las muestras en diferentes medios y en presencia de distintos tipos de antibióticos: sulfametoxazol, amoxicilina y tetraciclina. Los resultados del cultivo bacteriano fueron los siguientes: de todas las muestras que dieron positivos en resistencia antimicrobiana (100 muestras de 285), el 72 % fueron resistentes al sulfametoxazol, el 19.80 % dieron positivo a la amoxicilina y el 7.92 % de las muestras dieron positivo a la tetraciclina. En general los resultados indicaron que hay un considerable porcentaje de muestras que dieron positivo en resistencia a los distintos antibióticos, con un 35.44 % del total de muestras sembradas, mientras que el 64.56 % dieron negativo.
[EN] The aim of this undergraduate's final dissertation is researching the microbial strain which presents antibiotic resistance in a rabbit breeding slaughterhouse. This study was conducted by means of sampling in different areas within the slaughterhouse. Once sampling was concluded, a bacteria! culture followed using different mediums as well as different antibiotics: sulfamethoxazole, amoxicillin, and tetracycline. The results of the bacteria! culture were the following: from all the samplings which were positive in antimicrobial resistance {100 out of 285), 72 % of them were resistant to sulfamethoxazole, 19.80 % to amoxicillin, and 7.92 % to tetracycline. The conclusion is that there is a considerable number of samples which presented resistance to all the three antibiotics (35.44 %), while 64.56 % of the samples did not present any resistance.
