Cryptosporidium. Light micrograph of a human stool sample showing a stage in the life-cycle of the parasitic protozoan Cryptosporidium parvum. Rounded oocysts (pink) are seen,which contain the infective sporozoite stage. This parasite causes severe diarrhoea in humans,a condition known as cryptosporidiosis. It can be spread from person to person or from domestic animals to people. The main symptom is an attack of watery diarrhoea lasting about a week. Fever,nausea and abdominal pain may also occur. The infection is more severe in immune suppressed patients,and is common in patients suffering from AIDS. Magnification: x250 at 35mm size | |
