AAP/Sydney Morning Herald reports that a 12-week field trial involving the release of mosquitoes infected with a bacterium known to block the transmission of dengue will kick off Tuesday in several suburbs in north Queensland, Australia. "Laboratory research has shown that [the bacteria] Wolbachia acts like a vaccine for the mosquito, by monopolising resources needed by the dengue virus," according to the news service. "With up to 100 million people – largely from developing countries – being infected with dengue fever each year, a global solution was long overdue, [Scott O'Neill, of the University of Queensland, who is involved with the project] said" (Morgan, 1/3).
