Reovirus particles in a cell, TEM
Reovirus particles. Coloured transmission electron micrograph (TEM) of hundreds of particles (blue) of a reovirus infecting a host cell. The nucleus of the cell (green) is at centre. Viruses consist of a core of genetic material enveloped in protein coats. They rely on cellular genetic replication processes to make copies of themselves. A virus particle will infect a cell and then use the cell to make hundreds of copies of itself. This will kill the cell, and the next generation of virus particles is released to infect more cells. The reoviruses can cause febrile convulsions due to high temperatures when they infect humans

EDITORS COMMENTS
This image showcases the intricate world of viruses within a host cell. In this coloured transmission electron micrograph (TEM), hundreds of reovirus particles are seen infecting a cell, with their vibrant blue hue contrasting against the green nucleus at the center. Viruses, such as these reoviruses, possess a core of genetic material enclosed in protein coats. They rely on cellular genetic replication processes to reproduce themselves. Once inside a cell, a virus particle hijacks its machinery to produce numerous copies of itself. This relentless replication ultimately leads to the death of the infected cell, releasing the next generation of virus particles that go on to infect more cells. The consequences of reovirus infection can be severe for humans, causing febrile convulsions due to high temperatures. Understanding and studying these microscopic biological entities is crucial in advancing our knowledge in virology and medicine. Through this false-coloured micrograph captured by a transmission electron microscope (TEM), we gain insight into the complex interactions between viruses and their hosts at an incredibly detailed level. The beauty and complexity depicted here remind us of both the delicate balance within our own bodies and the ongoing battle between pathogens and our immune systems.
