electron micrograph of M. paratuberculosis
electron microscopes allow us to see the surface of extraordinarily
small things like M. paratuberculosis bacteria. Notice how
this bacterium grows in clumps and has a rough, waxy cell wall.
The cell wall is responsible for the bacterium's resistance to antibiotics,
chemical disinfectants, and environmental factors like heat and
is among the most popular photographs of this website. If you copy
