H1N1 Influenza A virus particles,coloured transmission electron micrograph (TEM). This influenza virus can infect multiple species and is the most virulent human pathogen of the three influenza types (A,B and C). The virus consists of ribonucleic acid (RNA),surrounded by a nucleocapsid (blue) and a lipid envelope (purple). In the envelope are two types of protein spike,haemagglutinin (H) and neuraminidase (N),which determine the strain of virus. Magnification: x142,900 when printed at 10 centimetres tall | |
