Abstract

Itacaiunas and Curionopolis viruses were isolated from Culicoides midges in Parauapebas municipality, Pará state, Brazil, in 1984 and 1985, respectively. Itacaiunas virus infected newborn mice and mosquito cells (C6/36), but did not replicate in some mammalian cell lineages; while Curionopolis virus infected only mice. Neither virus showed a serological relationship with any of the 195 known arboviruses circulating in Brazil, nor against 38 other rhabdoviruses isolated worldwide. Both virus particles are bullet-shaped and similar in morphology to that observed for other members of the family Rhabdoviridae. Partial nucleotide sequencing of the N protein showed that those two viruses constitute a separate clade in the family Rhabdoviridae, which we propose to be a new genus, designated Bracorhabdovirus.
