As the view shows when Jarrod is looking down the microscope, an image of an virus (Looks like the number Nine) is shown.
At that period of time it was not possible to achieve that level of magnification, and was only visible through an electron microscope, as a virus is too small to be seen with a simple ordinary microscope.
Everywhere from 10 to 100 times smaller than bacteria. "The first images of viruses were obtained upon the invention of electron microscopy in 1931 by the German engineers Ernst Ruska and Max Knoll."
