Hepatitis C viruses, TEM
Hepatitis C viruses. Coloured transmission electron micrograph (TEM) of hepatitis C virus particles (orange) infecting cultured liver cells (green). The virus consists of a core of RNA (ribonucleic acid) enclosed in a capsid, and surrounding by a glycoprotein envelope. It infects liver cells causing an inflammatory disease that can lead to degeneration and scarring (cirrhosis). It is transmitted by blood-to-blood contact. There is no vaccine for hepatitis C. Magnification: x20,000 when printed at 10 centimetres wide.
