A family of large icosahedral DNA viruses infecting insects and poikilothermic vertebrates. Genera include IRIDOVIRUS; RANAVIRUS; Chloriridovirus; Megalocytivirus; and Lymphocystivirus.

A genus of IRIDOVIRIDAE which infects fish, amphibians and reptiles. It is non-pathogenic for its natural host, Rana pipiens, but is lethal for other frogs, toads, turtles and salamanders. Frog virus 3 is the type species.

A genus of IRIDOVIRIDAE comprising small iridescent insect viruses. The infected larvae and purified virus pellets exhibit a blue to purple iridescence.

DNA virus infections refer to diseases caused by viruses that incorporate double-stranded or single-stranded DNA as their genetic material, replicating within host cell nucleus or cytoplasm, and including various families such as Herpesviridae, Adenoviridae, Papillomaviridae, and Parvoviridae.

Diseases of freshwater, marine, hatchery or aquarium fish. This term includes diseases of both teleosts (true fish) and elasmobranchs (sharks, rays and skates).

The most diversified of all fish orders and the largest vertebrate order. It includes many of the commonly known fish such as porgies, croakers, sunfishes, dolphin fish, mackerels, TUNA, etc.

The complete genetic complement contained in a DNA or RNA molecule in a virus.

Proteins found in any species of virus.
