Subfamily: Betairidovirinae

Genus: Decapodiridovirus

Distinguishing features

Decapodiridoviruses are large (158 nm) icosahedral viruses that infect penaeid shrimp and crayfish. 

Virion

Other than diameter (158 nm) and icosahedral symmetry, little is known about members of this family. 

Family: Iridoviridae

Subfamily: Betairidovirinae

Family: Iridoviridae

Subfamily: Alphairidovirinae

Subfamily: Alphairidovirinae

Genus: Ranavirus

Distinguishing features

Ranaviruses infect one or more species within the classes Reptilia, Amphibia and Osteichthyes and cause systemic infections. Depending upon the virus and the age and health of the host, infections result in a variety of clinical signs such as internal organ hemorrhage, skin sloughing and external petechia. Among currently identified ranaviruses, sequence identity within the major capsid protein is approximately 70% or higher.
