Bacterial Disease Identification

The question asks to identify which disease among the given options is caused by bacteria.

Understanding the causative agents (like bacteria or viruses) of diseases is crucial for biology and health-related studies.

• Smallpox: Caused by the Variola virus, also a virus.
• Anthrax: Caused by the bacterium Bacillus anthracis. This is a bacterial disease.
