Study Notes
Basic Shapes of Bacteria
- Bacteria primarily exhibit three fundamental shapes: Cocci, Bacilli, and Spirilla.
Cocci
- Cocci are spherical in shape.
- Cocci can exist as single cells or in various formations such as pairs (diplococci), chains (streptococci), or clusters (staphylococci).
Bacilli
- Bacilli have a rod-like appearance.
- This shape allows for greater surface area, which aids in nutrient absorption.
Spirilla
- Spirilla are characterized by a spiral shape.
- They can also be flexible or rigid in form, contributing to their motility through fluids.
