Disease resistance successfully spread from modified to wild mosquitoes

Using genetically modified mosquitoes to reduce or prevent the spread of disease is a rapidly expanding field of investigation. One challenge is ensuring that GM mosquitoes can mate with their wild counterparts so the desired modification is spread in the wild population. Investigators at Johns Hopkins University have engineered mosquitoes with an altered microbiota that suppresses human malaria-causing parasites. These GM mosquitos preferred to mate with wild mosquitoes and passed the desired protection to offspring.
