A new, holistic approach to biology is giving researchers new insights into how the Dengue and Zika viruses attack their hosts and, in the case of Zika, affect brain development. Published Dec. 13 in the journal Cell, the work may open up new ways to think about treating virus infections or mitigating their effects.
Virus-suppressing Bacteria Could Control Transmission by Mosquitoes
Mosquitos infected with the bacteria Wolbachia are significantly worse vectors for dengue virus, but how to establish and spread Wolbachia in an urban mosquito population is unclear. A study published May 30 in the open access journal PLOS Biology shows that over time, strategic releases of mosquitoes infected with the dengue-suppressing bacteria may be enough to allow the virus-resistant insects to spread across large cities.
