U.S. researchers found that the gut bacteria in Anopheles mosquitoes help protect them from being infected with the malaria-causing parasite Plasmodium falciparum and that removing this gut bacteria through antibiotics may make the mosquitoes more vulnerable to the parasite. The study's senior author said the bacteria could be introduced to mosquitoes to strengthen their immunity to the malarial parasite and limit their potential to spread the disease.
