View of Aedes aegypti mosquitoes infected with the Wolbachia bacterium --which reduces mosquito transmitted diseases such as dengue and chikungunya by shortening adult lifespan, affect mosquito reproduction and interfere with pathogen replication-- at the Oswaldo Cruz foundation in Rio de Janeiro, Brazil, on October 2, 2014.
