Abstract: The treatments against avian Colibacilosis have certain limitations, since the antimicrobial resistance has increased significantly and treatment may be ineffective. Prebiotics, administered as additives to animal, produce beneficial effects through changes in the microbial population of your digestive tract and which aims to ensure the normal balance of populations beneficial bacteria and dangerous to the digestive system. Yeasts such as Saccharomyces (S.) cerevisiae occupy sites of connection in the intestinal mucosa forming a physical barrier to potential pathogenic bacteria. Thus, these bacteria would be excluded by competition. The aim of this study was to assess the antibiotic sensitivity of strains of E. coli isolated from broiler sheds which used S. cerevisiae as an additive and others that did not use them. The E. coli strains were sensitive to cefotaxime, chloramphenicol and trimetoprimsulfa on samples for bird supplemented. In both groups there was a marked resistance to other antibiotics studied in this work.
