斑节对虾“红体病”细菌性病原的初步研究

Study on Bacterial Pathogen of " Red Body Disease ” in Penaeus monodon

从患“红体病”的斑节对虾中分离到８个菌株，通过致病力试验证实其中两个菌株是引起斑节对虾“红体病”的主要病原，使对虾死亡率分别达到７０％和９０％。根据生化试验，确定这两个菌株分别是嗜水气单胞菌和副溶血弧菌。抗药性实验的结果表明，嗜水气单胞菌菌株对强力霉素较为敏感，副溶血弧菌菌株对氟哌酸、红霉素、青霉素和强力霉素较为敏感。

strains of bacteria were isolated from diseased Penaeus monodon. Among them, two strains were found to be the main pathogens causing ' red body disease ' in cultured P.monodon, with a mortality of 70% and 90% respectively . Based on biochemical test results, these two strains were classfied as Aeromonas hydrophila and Vibrio parahemolyticus. The strain of A. hydrophila was very sensitive to doxycycinum, while the strain of V. parahemolyticus was very sensitive to norfloxacinum, erythromycinum, penicilin and doxycycinum.
