Which disease is NOT caused by bacteria?

Athlete's foot is caused by a fungal infection, specifically a type of fungus known as dermatophytes, rather than bacteria. Fungal infections differ from bacterial infections in their structure and methods of reproduction. While bacteria are single-celled organisms that can reproduce independently and can cause a variety of diseases, fungi have a more complex cellular structure and often require a living host or organic material to thrive.

Cholera, syphilis, and tetanus are all caused by specific types of bacteria. Cholera is caused by Vibrio cholerae, syphilis is caused by Treponema pallidum, and tetanus is caused by Clostridium tetani. Understanding the different pathogens responsible for various diseases is crucial in the field of infection control and helps to inform appropriate treatment and prevention strategies.
