What are the bacterial shapes?

Bacteria exhibit several shapes, which are used to classify them: 1. Cocci: Spherical or round-shaped bacteria (e.g., Streptococcus). 2. Bacilli: Rod-shaped bacteria (e.g., Escherichia coli). 3. Spirilla: Spiral-shaped bacteria (e.g., Spirillum). 4. Vibrios: Comma-shaped bacteria (e.g., Vibrio cholerae). 5. Coccobacilli: Short, oval-shaped bacteria that resemble a combination of cocci and bacilli (e.g., Haemophilus influenzae).
