Persistence of Lymphocystis Disease Virus (LCDV) in Seawater

In this study, the persistence of LCDV in natural (raw), treated (autoclaved and filtered) and synthetic seawater held at 22 and 18  °C has been evaluated. The estimated T99 values for LCDV in seawater ranged from 2.7 to 242 days depending on seawater type and temperature, with the highest value recorded at 22  °C in autoclaved seawater. Microbiota and temperature seem to be the main factors affecting the persistence of LCDV in seawater. The results indicated that LCDV is more stable in treated seawater than most of the fish pathogenic viruses studied so far, supporting the relevance of this medium for the prevalence of LCD in fish farms.
