Molluscum contagiosum virus, TEM
Molluscum contagiosum virus. Coloured transmission electron micrograph (TEM) of two molluscum contagiosum virus (MCV) particles. MCV is a poxvirus that causes molluscum contagiosum in humans, producing many small raised lesions on the skin. This virus consists of a DNA (deoxyribonucleic acid) core in a protein coat, or capsid, surrounded by an envelope. The proteins allow the particles to enter and leave host cells. MCV reproduces by entering cells and hijacking their biochemical machinery, producing many copies of itself. Molluscum contagiosum usually clears up in a few months but may require medical treatment. This sample of MCV was taken from an eye lesion. Magnification: x102, 000 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the Molluscum contagiosum virus, a poxvirus that causes molluscum contagiosum in humans. The image, captured using a transmission electron microscope (TEM), reveals two vibrant-colored MCV particles. These particles consist of a DNA core enclosed within a protein coat and surrounded by an envelope. MCV is notorious for producing numerous small raised lesions on the skin, resulting in the characteristic symptoms of molluscum contagiosum. This virus has the remarkable ability to enter and exit host cells through its proteins, enabling it to reproduce by exploiting their biochemical machinery and generating multiple copies of itself. The sample used for this TEM image was extracted from an eye lesion affected by molluscum contagiosum. With a magnification level of x102,000 when printed at 10 centimeters wide, this photograph provides an up-close look at the intricate details of this pathogenic microorganism. While molluscum contagiosum typically resolves within several months, medical intervention may be necessary in some cases. Understanding the structure and behavior of viruses like MCV plays a crucial role in developing effective treatments and preventive measures against these infectious agents. This visually striking image not only highlights the biological complexity of MCV but also serves as a reminder of the ongoing battle between pathogens and our immune systems—a constant struggle that fuels advancements in medicine and virology research.
