Abstract:

When Bacillus licheniformis was administered to the white shrimp, Litopenaeus vannamei, although the total bacterial counts in the intestinal tract of the shrimp remained constant, Vibrio numbers significantly decreased (P < 0.05). Haemocyte counts together with phenoloxidase and superoxide dismutase activities of the shrimp were significantly higher (P < 0.05) in treatments than in the control. Thus, administration of B. licheniformis can improve the white shrimp's intestinal microflora and its immune ability.
