Rounded oocysts (pink) are seen,which contain the infective sporozoite stage. This parasite causes severe diarrhoea in 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. Phase contrast technique. Magnification: x500 at 35mm size | |
