Resumen
The effect of inulin and probiotic bacteria on the growth, survival, immune response and viral
prevalence of white spot syndrome virus (WSSV) in white shrimp was evaluated. Presumptive bacilli
and lactic acid bacteria (LAB) were characterized for hemolytic and enzymatic activity, hydrophobicity
and antagonism against Vibrio. Selected isolates (Bacilli and LAB) were included in the diet of juvenile
shrimp. Two bioassays were conducted with treatments by triplicate (10 shrimp per replicate) with
inulin and inulin and bacteria. Fourteen LAB and six bacilli isolates had potential as probiotics. Survival
and growth was not affected by the addition of the inulin and bacteria to diet. Inulin and bacteria
improved immunity in cultured shrimp. Also, these feed additives reduced the prevalence of WSSV in
cultured shrimp.
