Parasitic protozoa on intestinal surface. Coloured transmission electron micrograph (TEM) of several meront stages of Cryptosporidium sp. protozoan parasites (round) on an intestinal surface. The surface is covered in microvilli strands. Meronts feed through the yellow structures attaching them to the surface. The meront stage of the life cycle involves asexual reproduction to form merozoites (blue). When released,the merozoites may repeat asexual reproduction,or may reproduce sexually to form the oocyst stage that passes between hosts in infected faeces. This parasite causes diarrhoea.
