Staphylococcus aureus is a medically important species of spherical, gram-positive bacteria that form grape-like clusters. It is a common cause of wound infections. Because some strains of S. aureus are resistant to many antibiotics, these skin infections can spread to other areas of the body and become serious, sometimes resulting in amputations or death if not treated with effective medications.

Staphylococcus aureus Clinical Characteristics

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.
