HUMAN CORONAVIRUS, TEM
Human coronavirus. Coloured transmission electron micrograph (TEM) of Human coronavirus particles (purple circles). Coronaviruses primarily infect the upper respiratory and gastrointestinal tract and can cause the common cold, gastrointestinal infections and SARS (severe acute respiratory syndrome). Coronaviruses are named after the corona (crown) of surface proteins (dark dots) that are used to penetrate a host cell. Once inside the cell, the virus particles (virions) use the cell's machinery to make more copies of themselves. Magnification: x67,000 when printed 10 centimetres tall.
