Taxonomy of tomato spotted wilt tospovirus

Tomato spotted wilt virus (candidate EPPO A2 organism) was previously thought to be the only member of the tospovirus group within the Bunyaviridae until recently the impatiens strain of TSWV was characterized as a separate virus and was named impatiens necrotic spot tospovirus. TSWV no longer being the only member of its group, it now becomes conventional to refer to it as tomato spotted wilt tospovirus.
Serological characterization and differentiation of isolates of TSWV in Germany showed that a third virus can clearly be distinguished from the other tospoviruses by specific antibodies to N nucleoprotein. TSWV isolates could be further differentiated into three serotypes by ELISA.
