Sumario:The e ffect of three di erent probiotic strains of Bacillus (B1, B2 and B3) isolated from the digestive tract of Pterophyllum scalare against Aeromonas hydrophila was evaluated. All the sh that where fed with the di erent probiotic strains obtained higher resistance to the pathogen inoculation since they did not developed any signs of illness nor lesions and they stayed healthy until the end of the experiment, with an observed survival of 100 %. On the other hand, the sh where the probiotic bacteria were not administrated developed the infectious process caused by Aeromonas hydrophila with signs of illness and lesions in the gills and hemorrhagic eyes, irregular swim, and injuries on the skin. The survival in these treatments was barely up to 8 %.
