Final answer:

Bacteria are classified into shapes such as spherical (coccus), rod-shaped (bacillus), spiral (spirillum), and comma-shaped (vibrio), with each having different arrangements. Examples include Staphylococcus aureus for coccus, Escherichia coli for bacillus, Spirillum minus for spirillum, and Vibrio cholerae for vibrio.

Step-by-step explanation:

Bacteria are categorized based on their shapes, and there are four common shapes of bacteria:

  • Coccus - These are spherical-shaped bacteria. An example of coccus bacteria is Staphylococcus aureus, which often appears in clusters resembling bunches of grapes.
  • Bacillus - These are rod-shaped bacteria. One familiar example of bacillus bacteria is Escherichia coli, typically found in the intestines of humans and animals.
  • Spirillum - These bacteria are spiral or corkscrew-shaped. An example is Spirillum minus, known for causing rat-bite fever.
  • Vibrio - These bacteria are comma-shaped. Vibrio cholerae, the causative agent of cholera, is an example of vibrio-shaped bacteria.

Each shape may have specific arrangements, like pairs, chains, or clusters, depending on how the bacteria divide and grow.
