Cryptosporidium protozoan. Coloured scanning electron micrograph (SEM) of a Cryptosporidium parvum protozoan oocyst (green) with unidentified bacteria (rod-shaped). This parasite causes cryptosporidiosis when ingested by humans. The symptoms of this disease include diarrhoea,stomach cramps and a slight fever. The oocyst releases an infective sporozoite stage (not seen),which attaches to the lining of the intestinal wall. There is no effective cure,but fluid intake relieves dehydration. In immuno-compromised individuals,such as those suffering from AIDS,the disease can be severe or even fatal. Magnification unknown | |
