Invertebrate Iridovirus (IIV) is a type of virus that primarily infects invertebrates, such as insects and crustaceans. It belongs to the family Iridoviridae and is known for causing significant diseases in various aquatic and terrestrial invertebrate species. The virus can lead to high mortality rates, particularly in populations of commercially important species like shrimp. IIV is characterized by its large, double-stranded DNA genome and can be transmitted through direct contact or contaminated environments. Research on Invertebrate Iridovirus is crucial for understanding its impact on ecosystems and for developing strategies to manage outbreaks in aquaculture, particularly in relation to shrimp farming and marine biodiversity.
