[目的]研究聚维酮碘作为一种水产养殖上常用的消毒剂对气单胞菌的抑菌杀菌效果。[方法]以气单胞菌属标准株ATCC7966和分离自患病鱼及养殖环境的气单胞菌为试验菌株,通过肉汤二倍稀释法研究聚维酮碘的抑菌杀菌作用。[结果]聚维酮碘在低浓度时能抑制气单胞菌的生长增殖,高浓度时杀灭细菌,其对Aeromonas sp. T1、Aeromonas sp. T2、Aeromonas sp. T4菌株的最小抑菌浓度为125. 00mg/L,最小杀菌浓度为4.00g/L;其对ATCC7966、Aeromonas sp. T3、Aeromonas sp. T5、Aeromonas sp. T6菌株的最小抑菌浓度为250.00 mg/L,最小杀菌浓度为8.00 g/L。[结论]为聚维酮碘的合理使用提供了一定的依据。
[Objective] The research aimed to study the bacteriostatic and bactericidal effect of Povidone as a common disinfectant on aquaculture. [Method] The antibacterial and bactericidal activities of Povidone Iodine were studied by double dilution method of broth with Aeromonas ATCC7966 and Aeromonas isolated from diseased fish and culture environment as test strains. [Result] Povidone iodine could inhibit the growth and proliferation of Aeromonas at a low concentration, and kill the bacteria at high concentration. The minimum inhibitory concentration of Povidone on Aeromonas sp. T1, Aeromonas sp. T2, Aeromonas sp. T4 The minimum bactericidal concentration was 125.00 mg / L and the minimum bactericidal concentration was 4.00 g / L. The minimum inhibitory concentration against ATCC7966, Aeromonas sp. T3, Aeromonas sp. T5 and Aeromonas sp. T6 strains was 250.00 mg / 8.00 g / L. [Conclusion] This provided some basis for the rational use of Povidone iodine.
