Virucidal effect of disinfectants against Oncorhynchus masou virus (OMV)

Abstract

Virucidal effects of six kinds of disinfectants were examined against Oncorhynchus masou virus (OMV), and infectious pancreatic necrosis virus (IPNV), infectious hematopoietic necrosis virus (IHNV) and hirame rhabdovirus (HIRRV). At 15°C for 20 min, minimum concentrations showing 100% plaque reduction of OMV by iodophor, sodium hypochlorite solution, benzalkonium chloride solution, saponated cresol solution, formaldehyde solution and potassium permanganate solution were 40, 50, 100, 100, 3,500 and 16 ppm, respectively. Susceptibility of OMV against these disinfectants was higher than that of IPNV, IHNV and HIRRV, suggesting that the usage of disinfectants against IPNV and/or IHNV is also effective against OMV.
