    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.

    Molecular characterization and sequecing analysis of SARS-CoV-2 genome in Minas Gerais, Brazil
    (2022) FERREIRA, Giulia Magalhaes; CLARO, Ingra Morales; GROSCHE, Victoria Riquena; CANDIDO, Darlan; JOSE, Diego Pandelo; ROCHA, Esmenia Coelho; COLETTI, Thais de Moura; MANULI, Erika Regina; JR, Nelson Gaburo; FARIA, Nuno Rodrigues; SABINO, Ester Cerdeira; JESUS, Jaqueline Goes de; JARDIM, Ana Carolina Gomes
    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in Wuhan, China, is the causative agent of the coronavirus disease 2019 (COVID-19). Since its first notification in Sa similar to o Paulo state (SP) on 26th February 2020, more than 22,300,000 cases and 619,000 deaths were reported in Brazil. In early pandemic, SARS-CoV-2 spread locally, however, over time, this virus was disseminated to other regions of the country. Herein, we performed genomic sequencing and phylogenetic analysis of SARS-CoV-2 using 20 clinical samples of COVID-19 confirmed cases from 9 cities of Minas Gerais state (MG), in order to evaluate the molecular properties of circulating viral strains in this locality from March to May 2020. Our analyses demonstrated the circulation of B.1 lineage isolates in the investigated locations and nucleotide substitutions were observed into the genomic regions related to important viral structures. Additionally, sequences generated in this study clustered with isolates from SP, suggesting a dissemination route between these two states. Alternatively, monophyletic groups of sequences from MG and other states or country were observed, indicating independent events of virus introduction. These results reinforce the need of genomic surveillance for understand the ongoing spread of emerging viral pathogens.
