Following his definitive disproof of spontaneous generation, Louis Pasteur articulated the phrase 'Omne vivum ex vivo' (meaning 'Life only comes from life') during a $${}1864$$ lecture. By declaring that 'life is a germ and a germ is life,' he delivered a final, mortal blow to the doctrine of spontaneous generation.

In $${}1862$$, Louis Pasteur conducted a series of experiments using flasks with long, twisted necks (swan-neck flasks) containing sterilized, boiled broth. The design allowed air to be exchanged but trapped airborne microorganisms in the bends of the neck, maintaining the sterility of the broth as long as the neck remained intact. If the neck was broken, microbes were introduced and contaminated the broth. This set of experiments irrefutably disproved the theory of spontaneous generation by showing that a 'life force' was not responsible for microbial growth, earning Pasteur the Alhumbert Prize.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
