Overview

Red sea bream iridoviral disease (RSIVD) is caused by infection with red sea bream iridovirus (RSIV) – a virus in the genus Megalocytivirus. RSIVD is a significant cause of mortality in farmed red sea bream (Pagrus major) and more than 30 other species of cultured marine fish (Matsuoka et al., 1996; Kawakami and Nakajima, 2002) belonging mainly to the orders Perciformes and Pleuronectiformes. First recorded in Japan in 1990, the disease is also widely distributed in East and South-East Asia (reviewed by Kurita and Nakajima, 2012). Affected fish become lethargic, exhibit severe anaemia, petechiae of the gills, and enlargement of the spleen (Nakajima et al., 2001).

For disease control, a formalin-killed vaccine was developed and is commercially available in Japan for several fish species (Nakajima et al., 2001).

Many RSIV-like viruses from cultured marine and freshwater fish and tropical ornamental fish have been reported mainly in East and South-East Asia (reviewed by Kurita and Nakajima, 2012). The various isolates include infectious spleen and kidney necrosis virus (ISKNV), Taiwan grouper iridovirus (TGIV), turbot reddish body iridovirus (TRBIV), rock bream iridovirus (RBIV) and dwarf gourami iridovirus. These viruses are closely related to RSIV morphologically and genetically, and the pathology of infected fish is similar to RSIVD. Given the wide host range of RSIV, some of these viruses are likely isolates of RSIV, whereas others likely represent different, but closely related, viral species. Genetic analysis suggests that two additional viral species exist in the genus Megalocytivirus. One of those is represented by ISKNV isolated from freshwater Chinese perch (Siniperca chuatsi) and another by TRBIV isolated from turbot (Scophthalmus maximus) (reviewed by Kurita and Nakajima, 2012).

RSIVD is on the list of diseases notifiable to the World Organisation for Animal Health (OIE). The distribution section contains data from OIE's WAHID database on disease occurrence. For further information on this disease from OIE, see the website: www.oie.int.
