Mosquitoes vs. malaria: How we can win the fight
..." When a blood-feeding Anopheles mosquito bites an infected
organism, the insect feeds on its blood - taking in the malaria-causing Plasmodium. After three weeks of developing within the mosquito, the Plasmodium moves from the insect gut into the salivary glands and is ready for transmission: at the next bloo...
