Colorized transmission electron micrograph of influenza A/H3N2 virus particles, isolated from a patient sample and then propagated in cell culture. Influenza A virus particles adapt shape—as ...

Colorized scanning electron micrograph of a cell heavily infected with SARS-CoV-2 virus particles (yellow), isolated from a patient sample. The black area in the image is extracellular space ...

As such, they are obligate parasites, which means that they cannot live or reproduce without a host. Consequently, viruses ... electron microscopy approaches to demonstrate that mammalian cells ...

Viruses have no metabolism of their own and must therefore infect host cells in order to ... immobilized viruses individually on microscopy glass surfaces. Cells were then seeded on top.
