A truly unique textbook, Microbiology teaches basic microbiology principles by taking a humorous but educational microbiological journey through everyday bodily functions and hygiene, through the intestinal tract. Covering major microbiology topics from an accessible, real-world perspective, chapters introduce concepts such as microbial structure and diversity, antibiotics and disinfection, spread of disease, wastewater management, and the beneficial use of microorganisms. The book also provides undergraduate students with insight into the current research on intestinal flora and changes during dieting, the usefulness of probiotics, intestinal diseases and their transfer, and more.
