ICTV Virus Taxonomy Profile: Nimaviridae

The family Nimaviridae includes the single species White spot syndrome virus, isolates of which infect a wide range of aquatic crustaceans and cause substantial economic losses. Virions are ellipsoid to bacilliform with a terminal thread-like extension. The circular dsDNA genome is 280-307 kbp with several homologous repeat regions. More than 80 structural and functional proteins have been characterized from 531 ORFs. White spot syndrome is a highly lethal, contagious disease associated with white spot syndrome virus infection of shrimps. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Nimaviridae, which is available at www.ictv.global/report/nimaviridae.
