Red Sea Bream Iridoviral Disease (RSIVD) is a prevalent infectious disease in South Korea fish farms. Detecting the early and preventing its spread through continuous surveillance activities are crucial for prevention management. To achieve this, we utilized virus concentration method seawater, providing non-invasive means to indirectly monitor progression. We investigated viral copy shedding ratio Oplegnathus fasciatus, known their high susceptibility red sea bream iridovirus (RSIV), under flow-through conditions. Horizontal transmission was confirmed RSIV-infected O. fasciatus uninfected Lateolabrax japonicus Acanthopagrus schlegelii. In conditions, mortality rate of increased with rising water temperature, it observed that maximum higher high-density conditions compared other density The study also horizontal between L. A.

ABSTRACT Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading significant economic losses in aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry have diameters ranging from 120 200 nm. Two distinct viral genus Megalocytivirus been identified: pagrus 1 lates . encompasses three genotypes: infectious spleen kidney necrosis virus, red seabream iridovirus, turbot reddish body whereas comprises single genotype, known as scale drop disease virus. Infection with is notifiable World Organisation for Animal Health. Over past two decades, progress made various aspects megalocytivirus biology, including understanding its molecular genetics, transmission modes, host ranges, pathogenic mechanisms, diagnostic methodologies, vaccines. This review provides comprehensive overview current megalocytiviruses, focusing on epidemiology, pathogenicity, immune evasion, prevention strategies megalocytiviruses. We hope that these findings will provide new insights development effective control megalocytiviral diseases.

Red sea bream iridovirus (RSIV) causes significant economic losses in the aquaculture industry. We analyzed pathogenicity of RSIV flathead grey mullets (Mugil cephalus), correlation histopathological lesions, and interspecies horizontal transmission, through immersion infection cohabitation challenges. Flathead mullets, which were challenged by infection, exhibited mortality at 14 24 days after exposure. Viral shedding seawater peaked 2-3 before or observed mortality. Specific lesions spleen kidney, between grade viral load was highest spleen. In a challenge, donors, healthy rock bream, red recipients. mullet 25 °C, with 106.0 copies L/g dpi. No any group 15 no detected 30 The virus shed from RSIV-infected caused transmission seawater. These findings suggest that rapid decision-making is warranted when managing disease fish farms.
