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.
