    Guapiacu virus, a new insect-specific flavivirus isolated from two species of Aedes mosquitoes from Brazil

    Classical insect-flaviviruses (cISFVs) and dual host-related insect-specific flavivirus (dISFV) are within the major group of insect-specific flavivirus. Remarkably dISFV are evolutionarily related to some of the pathogenic flavivirus, such as Zika and dengue viruses. The Evolutionary relatedness of dISFV to flavivirus allowed us to investigate the evolutionary principle of host adaptation. Additionally, dISFV can be used for the development of flavivirus vaccines and to explore underlying principles of mammalian pathogenicity. Here we describe the genetic characterization of a novel putative dISFV, termed Guapiacu virus (GUAPV). Distinct strains of GUAPV were isolated from pools of Aedes terrens and Aedes scapularis mosquitoes. Additionally, we also detected viral GUAPV RNA in a plasma sample of an individual febrile from the Amazon region (North of Brazil). Although GUAPV did not replicate in tested mammalian cells, 3 ' UTR secondary structures duplication and codon usage index were similar to pathogenic flavivirus.

    Near full length genome of a recombinant (E/D) cosavirus strain from a rural area in the central region of Brazil
    (2018) COSTA, Antonio Charlys da; LUCHS, Adriana; MILAGRES, Flavio Augusto de Padua; KOMNINAKIS, Shirley Vasconcelos; GILL, Danielle Elise; LOBATO, Marcia Cristina Alves Brito Sayao; BRUSTULIN, Rafael; CHAGAS, Rogerio Togisaki das; ABRAO, Maria de Fatima Neves dos Santos; SOARES, Cassia Vitoria de Deus Alves; DENG, Xutao; SABINO, Ester Cerdeira; DELWART, Eric; LEAL, Elcio
    In the present article we report the nearly full length genome of a Cosavirus strain (BRTO-83) isolated from a child with acute gastroenteritis, and who is an inhabitant of a rural area in the central region of Brazil. The sample was previously screened and negative for both: common enteric viruses (i.e. rotavirus and norovirus), bacteria, endoparasites and helminthes. Evolutionary analysis and phylogenetic inferences indicated that the Brazilian BRTO-83 Cosavirus strain was a recombinant virus highly related to the E/D recombinant NG385 strain (Genbank JN867757), which was isolated in Nigeria from an acute flaccid paralysis patient. This is the first report of a recombinant E/D Cosavirus strain detected in Brazil, and the second genome described worldwide. Further surveillance and molecular studies are required to fully understand the epidemiology, distribution and evolution of the Cosavirus.
