RESUMEN
ABSTRACT Rio Negro virophage (RNV) was co-isolated with a strain of mimivirus named sambavirus, from Brazilian Amazon. We report the near complete genome sequence of RNV, the first virophage isolated in Brazil. We also present new microscopical data demonstrating that RNV particles have similar dimensions to that described to sputnik virophages.

Abstract: A case of dengue virus 3 (DENV-3) genotype I infection with neurological manifestations occurred in Belo Horizonte, Minas Gerais in October 2012. The serotype was detected by PCR, and the genotype was assessed by sequencing and phylogenetic analysis of the C-prM region. The virus causing neurological manifestations clustered with other sequences of DENV-3 genotype I. Because neurological manifestations of DENV are possibly misdiagnosed in Brazil, this study serves as an alert of the importance of DENV diagnoses in CNS infections.
