Beneficial effects of Bacillus licheniformis on the intestinal microflora and immunity of the white shrimp, Litopenaeus vannamei.
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.
