    A survey of flaviviruses in birds in green areas of Sao Paulo, Brazil
    (2016) ORICO, Lilian Dias; FERNANDES, Licia Natal; MELO, Marcos Antonio; ZWARG, Ticiana; LEVI, Jose Eduardo; MARRELLI, Mauro Toledo
    Introduction: This study aimed to investigate Flavivirus infection in birds captured in green areas of Sao Paulo. Methods: Oropharyngeal swabs, cloacal swabs, and blood samples from 170 birds captured in two green areas in Sao Paulo, Brazil were subjected to real time-polymerase chain reaction (RT-qPCR) analysis of Flavivirus specific NS5 gene fragment. Results: All samples were negative for the presence of viral ribonucleic acid (RNA). Conclusions: Despite the negative results, Flavivirus surveillance must be performed regularly due to favorable ecological conditions for virus circulation and transmission among birds in these areas and their close proximity to humans.

    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.
