Four bacterial strains isolated from the gastrointestinal tract of adult shrimp Litopenaeus vannamei, Vibrio alginolyticus UTM 102, Bacillus subtilis UTM 126, Roseobacter gallaeciensis SLV03, and Pseudomonas aestumarina SLV22, were evaluated for potential use as probiotics for shrimp. In vitro studies demonstrated antagonism against the shrimp-pathogenic bacterium, Vibrio parahaemolyticus PS-017. Feeding shrimp with diets containing the potential probiotics showed the best feed conversion ratio in comparison with the control groups. After feeding with the potential probiotics for 28 days, challenge by immersion indicated effectiveness at reducing disease caused by V. parahaemolyticus in shrimp.
从成年凡纳滨对虾胃肠道分离出的四株细菌，即溶藻弧菌UTM 102、枯草芽孢杆菌UTM 126、加利西亚玫瑰杆菌SLV03和嗜温假单胞菌SLV22，被评估作为对虾益生菌的潜在用途。体外研究表明它们对虾致病细菌副溶血性弧菌PS - 017具有拮抗作用。与对照组相比，用含有潜在益生菌的饲料喂养对虾显示出最佳的饲料转化率。在用潜在益生菌喂养28天后，浸浴攻毒表明其在降低对虾由副溶血性弧菌引起的疾病方面有效。
