However, each of these types possess their own peculiar characteristics which have evolved after separation from the original species. Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. They come in different shapes and sizes, and their sizes are measured in micrometer which is a millionth part of a meter. Listeria monocytogenes causes listeriosis, a serious infection caused by eating food contaminated with the bacteria. When the conditions are favorable, the bacteria again revert to their original state. The three basic shapes of bacteria include cocci (blue), bacilli (green), and spirochetes (red).
