“…The cumulative mortality rate after the transportation process clarified that the iodine-tranquillized group showed the lowest mortality rate amongst all groups; this could be attributed to the augmented effective role of MS-222 plus the antibacterial effect of iodine which protected fish from accidental bacterial infection during transportation and also decreased the pathogenic bacterial load and improved fish health status. Using iodine at a low dose as 100 ppm for a minimum 10 min of exposure time can effectively destruct germs (OIE 2009;Heiner et al 2010). Chatchawanchonteera et al (2015) reported that povidone-iodine at a dose of 100 ppm for 15-min exposure at 37 °C could inactivate 6 logs of S. agalactiae isolated from fish.…”

Fish transportation is a regular farming and experimental practice that mainly results in stress conditions that may extend to induce a high mortality rate. In the present experimental simulation, Oreochromis niloticus were transported for 2 h and maintained for another 6 h in transportation containers to assess the effect of tranquilization with tricaine methanesulfonate (MS-222) and/or the addition of iodine on mortality rate and restoring the normal physiological functions. Experimental fish were divided into four groups: group 1 (control) was transported in farm water without MS-222 or iodine, group (2) was transported in farm water supplemented with 40 mg/L of MS-222, fish in group (3) were transported in farm water supplemented with 40 mg/L of MS-222 + 10 ppm iodine, and fish in group (4) were transported in farm water containing 10 ppm iodine. Blood samples were collected for the determination of serum cortisol and glucose, while skin mucus was collected for assaying lysozyme, peroxidase and antibacterial activity; cumulative mortality rate; and food reflexes which were assessed at 0 h, 1 h, 6 h, 48 h, 7 days and 14 days post 2 h transportation. The results indicated that fish tranquilization with MS-222 and/or treatment with iodine mitigated the stress condition associated with transportation and accelerate restoration of the normal physiological and immunological status. So, it was recommended to use the MS-222 as a tranquillizer together with iodine as an antiseptic during transportation of O. niloticus.

“…To determine a practical minimal disinfecting concentration for 10% PVI over different contact times and temperatures, Heiner et al 41) exposed Escherchia coli to various dilutions of 10% PVI for 5, 15, and 30 min at 10, 20, and 30 o C, neutralized with 0.5% sodium thiosulfate, and determined mean viable colony forming units (CFUs). In results, no CFUs were observed after exposure to the 1:100 dilutions and after 15 min of exposure to the 1:1,000 dilutions across experimental temperatures.…”

Clostridium perfringens (C. perfringens) and Mycobacterium fortuitum (M. fortuitum) are associated with considerable diseases in animals and human. In this study, the disinfection efficacy of a commercial disinfectant composed to povidone-iodine (PVI) was evaluated against C. perfringens and M. fortuitum. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to C. perfringens and M. fortuitum for 30 min at 4 o C. The disinfectant and test bacteria were diluted with hard water (HW) or organic matter suspension (OM) according to treatment condition. On HW condition, the bactericidal activity of the disinfectant against C. perfringens and M. fortuitum was 50 and 80 fold dilutions, respectively. On OM condition, the bactericidal activity of the disinfectant against both C. perfringens and M. fortuitum was 15 fold dilutions. As the disinfectant composed to PVI possesses bactericidal efficacy against C. perfringens and M. fortuitum, the disinfectant solution can be used to control the spread of bacterial diseases.

The review summarizes the data on the main chemical and physiological properties of iodine and its capability of complexation with natural and synthetic polymers. Iodine is the best known antiseptic used to prevent and treat microbial infections. Its unique capability of complexation with certain polymers opens wide opportunities for targeted and prolonged delivery to target organs. Polymeric complexes with iodine have another color, other morphology, a higher electrical conductivity, and higher biological activity as compared with initial polymers. The formation of and ions is associated with iodine–polymer complexation. Iodine-containing biocompatible adhesive controlled-release formulations are designed as part of research into iodine–polymer complexes. The field is promising in terms of treating certain diseases because tolerance to iodine compounds does not usually develop in microbial cells.
