The Microbiology Study Brief is intended as a quick reference guide to fundamental concepts and processes related to the study of microbes and microorganisms. Ideal for students enrolled in an introduction to microbiology course as well as lifelong learners interested in advanced science topics. This Study Brief focuses on specific concepts related to the study of microbiology. This title provides a more in-depth treatment of basic concepts introduuced in our Biology and Cell Biology Study Briefs. The introduction to this Study Brief defines microbiology, identifies particular fields of specialization, and provides a short history that includes major contributors and contributions. An overview of microscopes and microscopy is included. Topics covered include: Prokaryotic cells (archaea and bacteria); gram-negative versus gram-positive bacterial characteristics; eukaryotes (algae, fungi, helminthes, lichens, protozoa and slime molds); viruses, prions and viroids; microbial metabolism; microbial genetics; recombinant DNA and biotechnology; and epidemiology. Some useful online resources for further reference and investigation are provided.
