A Field Guide To Bacteria

Bacteria are an integral aspect of every habitat in which they occur and affect the lives of humans, other animals, and plants in many ways. Too often, we equate bacterium with pathogen and think of bacteria as things to avoid. In a guide for naturalists, students, teachers and tourists alike, Betsey Dexter Dyer lets the reader know that it is possible to observe bacteria with all the senses. Many groups of bacteria can be easily identified in the field (or in the refrigerator) without a microscope.
