Containing 57 thoroughly class-tested exercises, this manual provides basic microbiology techniques with applications for undergraduate students in diverse areas, including the biological sciences, the allied health sciences, agriculture, environmental science, nutrition, pharmacy, and various pre-professional programs. The Ninth Edition features a new, four-color design and a dramatically new art program. Many of the illustrations have been re-rendered in a modern, realistic, three-dimensional style, and detailed, colorful photomicrographs that were once grouped together in a color insert are now integrated throughout the exercises. Experiments have been refined throughout, and a new exercise on parasitic helminths provides students with valuable practice in microscopic examination and observation.
