dc.descriptionThis study evaluated the mortality rate, histopathology and haematological param-eters of Arapaima gigas against Aeromonas hydrophila after 68 days of dietary probiotic supplementation with autochthonous bacterium Enterococcus faecium. Three experi-ments were carried out: the first assay evaluated the lethality of A. hydrophila, the second and the third assay evaluated the fish supplemented subjected to A. hydrophilalethal dose 30% (106 CFU ml−1) and lethal dose 100% (108CFU ml−1) respectively. The clinical signs, blood changes, histopathological alterations and mortalities were evalu-ated. At the first experiment, the concentrations of 106 and 108CFU.mL−1 with A. hy-drophila caused 33% and 100% of mortality. The A. hydrophila infection provoked clinical signs such as dark skin, ulceration, haemorrhage, pale gills and liver, hepatic alterations, hyperaemia, hepatic cord breakdown, cellular deforming, lipid degener-ation and necrosis. In the second experiment, no mortality occurred onto fish fed with probiotic. Furthermore, in the third experiment, fish submitted to probiotic sup-plementation showed reduction in mortality of 75% compared with the control and fish fed with probiotic diets at 108CFU g−1 not presented any clinical signs. For these reasons, Arapaima gigas juveniles previously submitted to probiotic supplementation with E. faecium (108CFU g−1) shows better physiological and immunological response, improving resistance against A. hydrophila infection.eng
