Abstract

Iridovirus is an icosahedral cytoplasmic double-stranded DNA virus with a genome size of 170-200kb. Outbreaks of fish iridovirus infection are characterized by their wide geographic distribution and broad host spectrum, especially in water temperatures of $25-27^{\circ}C$ Recently, the causative agent of high mortalities in flounder (Paralichthys olivaceus) was identified as fish iridovirus in Korea. Iridoviral infection repeatedly occurs in the same area for long periods, suggesting the possibility of viral infection in nursery. To examine this, the existence of iridovirus in juvenile flounders was detected by PCR using virus-specific primers. Antibodies induced against this virus were also examined using ELISA. As a result, juvenile fish in nursery were found to be previously infected with iridovirus, suggesting that proper prevention systems are required.
