Bacteria are an integral aspect of every habitat 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 fascinating guide perfect for naturalists, students, teachers, and tourists alike, Betsey Dexter Dyer lets us know that 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. Written for curious souls of all ages, A Field Guide to Bacteria opens our eyes-and noses and ears-to this hidden, or neglected, world around us.
