Brazil is a tropical country with a wide variety of flora and fauna that includes many arthropods, especially mosquitoes and midges. This ecological diversity facilitates the maintenance of arboviral cycles and the emergence of novel arboviral pathogens. Indeed, many outbreaks attributable to zoonotic arboviruses such as Oropouche, Mayaro, Rocio virus (ROCV), Saint Louis encephalitis virus (SLE...

Comparative sequence analysis of mosquito vitellogenin (Vg) genes was carried out to gain a better understanding of their evolution. The genomic clones of vitellogenin genes were isolated and sequenced from all three subfamilies of the family Culicidae including Culicinae (Aedes aegypti, Ochlerotatus atropalpus, Ae. polynesiensis, Ae. albopictus, Ochlerotatus triseriatus and Culex quinquefascia...

Seroprevalence rates were higher in the Wayampi and Wayana tribes li...
