Malaria ookinete, TEM
Malaria parasite. Image 5 of 10. Coloured transmission electron micrograph (TEM) of a sexual malaria ookinete in a mosquito gut wall. The ookinete (blue, Plasmodium sp.) is penetrating the gut (lower frame) of the mosquito (Anopheles sp.). This stage occurs after the sexual gametes, formed after the parasites are ingested by a feeding mosquito, fuse. The ookinete forms an oocyst in the wall, in which sporozoites, which infect humans, grow. Malaria later invades human red blood cells, causing fevers and anaemia. Magnification unknown. For the complete malaria parasite life cycle, see images M210/207-216

EDITORS COMMENTS
This print showcases a coloured transmission electron micrograph (TEM) of a malaria parasite known as the ookinete. In this image, we witness the remarkable moment when the ookinete, represented in blue and belonging to the Plasmodium species, penetrates the gut wall of a mosquito from the Anopheles genus. The ookinete stage occurs after sexual gametes are formed following ingestion by a feeding mosquito. Once fused, the ookinete establishes an oocyst within the gut wall where sporozoites develop. These sporozoites are responsible for infecting humans and causing malaria, which manifests as fevers and anaemia upon invading red blood cells. While magnification details remain unknown, this photograph offers us an extraordinary glimpse into one crucial step of the complex life cycle of malaria parasites. It serves as a reminder that mosquitoes act as vectors for transmitting this pathogenic microorganism to humans. With its vibrant colours and intricate details captured through TEM technology, this image not only fascinates those interested in biology and medicine but also highlights both the infectious nature of malaria and its impact on global health. Through scientific exploration like this, we gain valuable insights into disease-causing pathogens such as Plasmodium sp. , ultimately paving the way for improved prevention strategies and treatments in our ongoing battle against malaria.
