Malaria parasites. Image 9 of 10. Coloured transmission electron micrograph (TEM) of malaria sporozoites in a mosquito (Anopheles sp.) gut. The sporozoites (Plasmodium sp., green/pink) are seen bursting from an oocyst (lower left) on the gut wall of the mosquito. This stage, produced by asexual replication, will migrate to the mosquito's salivary glands, and will then infect humans when the mosquito feeds. Malaria later infects human red blood cells, causing anaemia, cyclic fevers and even death. Magnification unknown. For the complete malaria parasite life cycle, see images M210/207-216.
