Arbovirus expansion: new species of culicids infected by the Chikungunya virus in an urban park of Brazil.

Arbovirus expansion: new species of culicids infected by the Chikungunya virus in an urban park of Brazil. Acta Trop. 2020 May 23;:105538 Authors: de Melo Ximenes MFF, de Araújo Galvão JM, Inacio CLS, Macêdo E Silva VP, Pereira RLDN, Pinheiro MPG, de Medeiros Siva MM, Gomes CES Abstract The Dengue, Zika and Chikungunya viruses have been spreading in tropical regions, causing epidemics with high morbidity rates and fatal cases. The aim of this study was to assess the diversity and abundance of culicid species and the presence of arboviruses in mosquitoes, at the epicenter of an epidemic outbreak that occurred in people living near an urban Atlantic Forest park. Mosquitoes were captured with a Shannon trap between 2 and 6 pm in seven months of 2019. The Chikungunya virus was investigated according to the protocol described by Lanciotti (2007). The most abundant species were Wyeomyia bourrouli (66.9%) and Aedes albopictus (23.9%). Also captured were Aedes fluviatilis (3.2%); Haemagogus leucocelaenus (2.2%); Aedes scapularis (2.2%); Aedes aegypti (1.6%); Aedes serratus and (0.3%) and Aedes taeniorhynchus (0.3%). The Chikungunya virus was identified in A. aegypti females; A. albopictus females and males; Aedes fluviatilis and Wy.bourrouli. The presence of the Chikungunya virus in the afore mentioned mosquitoes reinforces the hypothesis that arbovirus expansion is associated with the participation of other mosquito species in the transm...
