Genomic and phenotypic characterization of the Oropouche virus strain implicated in the 2022–24 large‐scale outbreak in Brazil

Journal of Medical Virology, Volume 96, Issue 10, October 2024.
Abstract The Orthobunyavirus oropoucheense species encompasses a group of arthropod‐borne zoonotic viruses transmitted by biting midges to animals including humans. Several large‐scale human outbreaks caused by the prototype member of this species, Oropouche virus (OROV) have been documented since the 1970s and were primarily confined to the Amazon ...

Climate change is aggravating dengue and yellow fever transmission risk

Ecography, Volume 2024, Issue 10, October 2024.
Dengue and yellow fever have complex cycles, involving urban and sylvatic mosquitoes, and non‐human primate hosts. To date, efforts to assess the effect of climate change on these diseases have neglected the combination of such crucial factors. Recent studies only considered urban vectors.

Alpha‐mannosidase‐2 modulates arbovirus infection in a pathogen‐ and Wolbachia‐specific manner in Aedes aegypti mosquitoes

Insect Molecular Biology, Volume 33, Issue 4, Page 362-371, August 2024.
Mosquito genetic background can modulate Wolbachia pathogen‐blocking phenotypes. The alpha‐mannosidase‐2 gene has previously been identified as a potential candidate. αMan2 CRISPR KO mutagenesis suppresses dengue virus titres but increases Mayaro virus titres, in Wolbachia‐uninfected mosquitoes.
