Study Notes
Bacterial Shapes and Characteristics
- Cocci are round-shaped bacteria that divide in both planes.
- Bacilli are rod-like bacteria that divide only in one plane.
- Streptococci are bacteria that form chains and only divide in one plane.
Bacterial Infections and Gut Flora
- Enterobacteriaceae is a rod-like bacteria commonly found in gut flora, but can also cause infections in foreign locations.
Bacterial Structures and Functions
- A capsule is a structure that prevents phagocytosis by the body.
- Fimbriae/pili are structures that facilitate bacterial adhesion and conjugation.
- Peritrichous flagella have multiple organized flagella and move in linear motion.
- PHB granules in bacteria store polyhydroxybutyrate, a type of energy reserve.
Endospores and Sporulation
- Sporulation is the process by which a vegetative cell forms an endospore.
