[Objective] The aim of this study is to investigate the bacteriostatic and bactericidal efficacy of povidone iodine as one kind of disinfectants for aquaculture on Aeromonas. [Method] With the standard strain of Aeromonas ATCC7966 and the Aeromonas strains isolated from diseased fish or aquatic environment as the tested strains, the bacteriostatic and bactericidal efficacy of povidone iodine was studied by double broth dilution method. [Result] The povidone iodine could inhibit the growth of Aeromonas strains at lower concentration, and killed Aeromonas strains at higher concentration. The minimum bacteriostatic concentration (MIC) of povidone iodine on Aeromonas sp. T1, Aeromonas sp T2 and Aeromonas sp. T4 was 125.00 mg/L, and the minimum bactericidal concentration (MBC) was 4.00 g/L. Whereas, the minimum bacteriostatic concentration (MIC) of povidone iodine on ATCC7966, Aeromonas sp. T3, Aeromonas sp T5 and Aeromonas sp. T6 was 250.00 mg/L, and the minimum bactericidal concentration (MBC) was 8.00 g/L. [Conclusion] This study provides certain basis for reasonable application of povidone iodine.
