Cryptosporidium. Coloured Scanning electron micrograph (SEM) showing a stage in the life-cycle of the parasitic sporozoan (protozoan) Cryptosporidium parvum. Rounded oocysts are seen,which contain the infective sporozoite stage. This parasite causes severe diarrhoea in humans,a condition otherwise 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 occur. The infection is more severe in immune suppressed patients,and is common in patients suffering from AIDS. Magnification: x1360 at 6x4.5cm size | |
