Yersinia unleashed

The black plague is caused by the pathogen, Yersinia pestis. It only takes one Yersinia bacterium to cause an infection, which is deadly if not treated promptly. Immune cells (macrophages - purple/teal) were infected with Yersinia pestis (bright green), fixed, critically point dried, sputter coated with platinum, and imaged.

Bacteria (one of them is a bacterium) are very small organisms. They are prokaryotic microorganisms. Bacterial cells do not have a nucleus, and most have no organelles with membranes round them. However, they do have DNA, and their biochemistry is basically the same as other living things.

Micropillar with Pt Bridges

A micropillar is provided with lateral contacts in order to generate an in-plane electrical field inside the cavity. The contacts are formed by focused ion beam induced deposition of platinum between a gold layer and the micropillar. The image was colorized (Pt: blue, Au: yellow, micropillar: red).
