Viruses causing diarrhoea. Coloured transmission electron micrograph of two virus types causing diarrhoea in humans. The larger spheres & tubular forms are rotavirus particles; the smaller,brighter forms are astroviruses. Rotaviruses are probably the most common viral parasites of man,causing diarrhoea in the young. The smooth outer layer of whole particles resembles the rim of a wheel. The smaller astrovirus also causes diarrhoea & vomiting,particularly in children. Identification of these very small viruses is based on their vast numbers (in faeces) & a unique 5- or 6-pointed star on the surface. Magnification: x24,000 at 6x4.5cm size | |
