Before delving into cocci specifically, let us first understand the broad classification of bacterial shapes:
- Cocci: Spherical or round-shaped bacteria (e.g., Streptococcus, Staphylococcus).
- Bacilli: Rod-shaped bacteria (e.g., Escherichia coli).
- Spirochaetes: Slender, spiral, or corkscrew-shaped bacteria (e.g., Treponema pallidum).
- Vibrio: Comma-shaped bacteria (e.g., Vibrio cholerae).
- Star-shaped, pleomorphic, and other less common forms.
