    Classical insect-specific flaviviruses (cISFs) have been widely detected in different countries in the last decades. Here, we characterize the near full-length genomes of two cISFs detected in mosquitoes collected in the city of Macapa, state of Amapa, Amazon region of Brazil. A total of 105 pools of female mosquitos were analyzed by next-generation sequencing (NGS). Comparative genomics and phylogenetic analysis identified three strains of cell fusing agent virus (CFAV) and two of Culex flavivirus (CxFV). All sequences were obtained from pools of Culex sp., except for one sequence of CFAV detected in a pool of Aedes aegypti. Both CxFV strains are phylogenetically related to a strain isolated in 2012 in the Southeast region of Brazil. The CFAV strains are the first of this species to be identified in Brazil and one of them is highly divergent from other strains of CFAV that have been detected worldwide. In conclusion, CFAV and CxFV, circulate in mosquitoes in Brazil. One strain of CFAV is highly divergent from others previously described, suggesting that a novel strain of CFAV is present in this region.

    Characterization of insect-specific Culex flavivirus (Flaviviridae) nucleotide sequences in mosquitoes from urban parks in Sao Paulo, Brazil
    (2022) COLETTI, Thais de Moura; ROMANO, Camila Malta; URBINATTI, Paulo Roberto; TEIXEIRA, Renildo Souza; PEDROSA, Leila Weiss de Almeida; NARDI, Marcello Schiavo; NATAL, Delsio; COSTA, Antonio Charlys da; JESUS, Jaqueline Goes de; CLARO, Ingra Morales; SABINO, Ester Cerdeira; WITKIN, Steven S.; MARRELLI, Mauro Toledo; FERNANDES, Licia Natal
    Background: Despite their worldwide occurrence, the distribution and role of insect-specific flaviviruses (ISFs) remain unclear. Methods: We evaluated the presence of ISFs in mosquitoes collected in Sao Paulo, Brazil, using reverse transcription and semi-nested polymerase chain reaction (PCR). Some of the positive samples were subjected to nanopore sequencing. Results: Twelve mosquito pools (2.8%) tested positive for flavivirus infection. Nanopore sequencing was successfully performed on six samples. Phylogenetic analysis grouped these sequences into genotype 2 of Culex flavivirus (CxFV). Conclusions: The identification of CxFV genotype 2 at new locations in Sao Paulo highlights the importance of understanding the role of ISFs in mosquito vector competence.
