Connects the polyhedral head to the tail fibers and tail pins

Sheath

Helps with viral attachment to the receptors of the host cell surface for entry

Tail fibers/pins

A protein coat that surrounds the viral genome.

Capsid

Capsomer

A portion of the phospholipid membrane acquired through virion buds from a host cell.

Viral envelope

Bacteriophage replication involves 2 types of life cycles: The Lytic Cycle and the Lysogenic Cycle.

Bacteriophage Replication Cycles

Structures of Bacteriophages include:

- Capsid
- Viral genome
- Sheath
- Tail fibers

University of Southern Mississippi

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.
