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.

Many alphaproteobacteria are oligate or facultative bacteria that are also capable of living in harsh low-nutrient environments like deep oceanic currents, ice, or deep soil.

Alphaproteobacteria

Betaproteobacteria are diverse in their metabolic functions that allow them to adapt to different environments. Some betaproteobacteria are human pathogens. 

Betaproteobacteria

The gammaproteobacteria class consists of a large and diverse group of gram-negative bacteria. It consists of many pathogens. 

Gammaproteobacteria

Deltaproteobacteria

Epsilonproteobacteria is a small group of proteobacteria that require minimal oxygen to survive.
