Insect-specific flaviviruses (ISFVs) commonly infect vectors of mosquito-borne arboviruses. To investigate whether infection with an ISFV might affect mosquito flight behavior, we quantified flight behavior in Culex pipiens L. naturally infected with Culex flavivirus (CxFV). We observed a significant reduction in the scotophase (dark hours) flight activity of CxFV-positive mosquitoes relative t...
Goose erythrocytes preserved with glutaraldehyde were compared with fresh cells in hemagglutination and hemagglutination-inhibition tests for arbovirus antigens and antibodies. The glutaraldehyde-fixed cells were as sensitive and specific as theresh erythrocytes and were stable at 4 degrees C for 6 months.
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...

We isolated an arbovirus from bovine blood in Indonesia. The arbovirus was obtained from the plasma of a cow showing no clinical symptoms in West Java in February 2014, and was identified as Akabane virus (AKAV) by AKAV-specific RT-PCR and subsequent sequence analysis. Phylogenetic analysis based on partial S segment indicated the AKAV isolate, WJ-1SA/P/2014, was most closely related with two i...

recent of four unexpected arrivals of important arthropod-borne viral diseases in the Western Hemisphere over the past 20 years. It follows dengue, which entered this hemisphere stealthily over decades and then more aggressively in the 1990s; West Nile virus, which emerged in 1999; and chikungunya, which emerged in 2013. Are the successive migrations of these viruses unrelated, or do they refle...
