Hepatitis B viruses
Hepatitis B virus. Coloured transmission electron micrograph (TEM) of hepatitis B viruses (circles), a cause of liver inflammation. The inflammation is the immune response to the virus that invades liver cells to replicate itself. The virus has a coat (capsid, pink) bearing surface proteins (spikes), which the body detects as a foreign body (antigen). The complete virus is called a Dane particle and is approximately 42 nanometres in diameter. Hepatitis B is primarily transmitted by infected human blood, either in transfusions or on the shared needles of intravenous drug users. Magnification unknown

EDITORS COMMENTS
This print showcases the Hepatitis B virus, a notorious cause of liver inflammation. In this coloured transmission electron micrograph (TEM), we can observe numerous hepatitis B viruses resembling tiny circles. These minuscule invaders trigger an immune response within our bodies as they infiltrate liver cells to replicate themselves. The pink coat surrounding the virus, known as the capsid, is adorned with surface proteins or spikes. Interestingly, these spikes are recognized by our immune system as foreign antigens. The complete form of this virus is referred to as a Dane particle and measures approximately 42 nanometres in diameter. Hepatitis B primarily spreads through infected human blood, whether it be through transfusions or shared needles among intravenous drug users. This highly infectious pathogen poses a significant threat to public health worldwide. While the magnification level remains unknown for this image, its significance lies in shedding light on the intricate world of virology and biology at a microscopic level. Through electron micrograph technology, scientists gain valuable insights into understanding viral infections like Hepatitis B and developing effective preventive measures against them. This remarkable photograph from Science Photo Library serves not only as an educational tool but also highlights the urgent need for continued research and awareness regarding hepatitis B infection prevention strategies.
