Stability of snakehead (Ophiocephalus striatus) rhabdovirus under different environmental conditions
Snakehead rhabdovirus stored in cell culture medium was found to be relatively temperature resistant with ≥ 99.9% reduction in infectivity only occurring after 6 months at 15°C, 6 weeks at 25°C and 10 days at 35°C. At 25°C, virus stability was greatest in the range pH 5–7. Infectivity was less well retained at pH9 and rapidly lost at pH3 and pH11. Stability was poor in serum-free media with a 99.9% reduction in infectivity occurring in less than 48 hours at 25°C in de-ionized water, tap water, balanced salt solutions and artificial seawater.
