Genus Prymnesiovirus

Type Species

Chrysochromulina brevifilum virus PW1

(CbV-PW1)

Distinguishing Features

Viruses assigned to this genus probably have a common genome structure and infect members of the same marine algae, Chysochromulina brevifilum and C. strobilus. These viruses have been isolated from USA (Texas) coastal waters in three locations (Gulf of Mexico, Aransas Pass, and Laguna Madre). The particles contain a dsDNA genome and have a diameter ranging from 145 to 170  nm. The estimated burst size is 320 viruses per infected cell.
