The position of all these viruses within the family Picornaviridae is currently under review. They include agents such as bee acute paralysis, bee slow paralysis, bee virus X, Drosophila P and A viruses, sacbrood virus, Queensland fruitfly virus, Triatoma virus and aphid lethal paralysis virus. 4 - viruses morphologically resembling picornaviruses isolated from harbor seals and sea bass. Sequiviridae have many properties in common with picornaviruses. Virus infects vertebrates.
