Abstract Members of the family Marseilleviridae are giant viruses that have the ability to infect amoebas. Such viruses were initially described in 2009. Since then, this family has grown, and diverse members have been found in different environments and geographic locations. Previous phylogenetic analyses suggested the existence of four marseillevirus lineages. A fourth lineage was described with the discovery of the Brazilian marseillevirus (BrMr), isolated from Pampulha Lake, Brazil. Here we describe the isolation and characterization of the Golden marseillevirus (GMar), a new marseillevirus isolated from golden mussels ( Limnoperna fortunei ) in South of Brazil. This new representative of Marseilleviridae has circular, double-stranded (dsDNA) that contains 360, 610 base pairs and encodes 483 open read frames (ORFs). The complete virus genome was sequenced and phylogenic analyses indicated clear differences between this virus and other marseilleviruses. In addition, this is the only marseillevirus so far that has been isolated from mussels, and this report expands the diversity of environments from which giant viruses could be recovered.
