A strain of bacteria has been discovered that can infect mosquitoes and make the insects resistant to the malaria parasite. In the study, in the journal Science, researchers showed the parasite struggled to survive in infected mosquitoes. Since malaria is spread between people by the insects, it is hoped that giving mosquitoes malaria immunity could reduce human cases and experts claim this was a first, distant prospect for malaria control. Malaria is a major global disease. The World Health Organization estimates that 220 million people are infected annually and 660,000 die.
