F. colour SEM of oocysts on stomach of Anopheles
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

Malaria Malarial Parasite Plasmodium Protozoa Protozoan
EDITORS COMMENTS
This print offers a mesmerizing glimpse into the intricate world of nature's hidden battles. The false-color scanning electron micrograph showcases the stomach wall of an Anopheles mosquito, specifically Anopholes stephansii, infected with malarial parasites known as Plasmodium. The image reveals small rounded objects called oocysts that densely cover the exterior of the mosquito's stomach wall. These oocysts represent a crucial stage in the life cycle of the malaria parasite. As they grow in size, their contents divide to form sporozoites - tiny organisms responsible for transmitting malaria. When these oocysts burst open, countless sporozoites are released into the body cavity of the mosquito. Over time, these resilient creatures navigate their way towards the salivary gland. Once there, they patiently await their next opportunity to infect unsuspecting humans when a female mosquito takes her blood meal. This photograph not only highlights nature's complexity but also serves as a reminder of how delicate our ecosystem truly is. It sheds light on one of humanity's greatest challenges - combating malaria and its devastating impact on millions worldwide. Through this stunning visual representation captured by Science Photo Library, we gain insight into both scientific marvels and urgent global health concerns surrounding this deadly parasitic disease.
