Efficacy of a commercial disinfectant against Vibrio ordalii, Vibrio anguillarum, Francisella sp. and Infectious Pancreatic Necrosis Virus (IPNV) pathogens of Atlantic salmon (Salmo salar) farmed in Chile
The efficacy of the disinfectant Duplalim®, a synergistic blend of superquats and glutaraldehyde, was analysedin vitroagainst 4 fish pathogens. All concentrations tested (1:200 to 1:400 dilutions) were efficacious on killingVibrio ordaliiandVibrio anguillarumin seawater after 30 s, being the level o...
