False-colour scanning electron micrograph of the stomach wall of a mosquito Anopholes stephansii infected with malarial parasites Plasmodium. The small rounded objects covering the outside stomach wall are oocysts,a stage in the life cycle of the parasite. The oocysts grow in size & the contents divide to form sporozoites,which are dispersed through the body cavity when the oocyst bursts. The released sporozoites eventually reach the salivary gland of the mosquito & are transmitted to humans when the female takes a blood meal | |
