* Fungi: Many fungal species, including those that cause infections like athlete's foot, ringworm, and mold, reproduce and spread through spores.
* Bacteria: Some bacteria, such as Bacillus anthracis (anthrax) and Clostridium tetani (tetanus), form spores that can survive for long periods in the environment. These spores can then be inhaled or introduced into the body through wounds, leading to infection.
* Protozoa: While less common than fungi and bacteria, some protozoa, like Cryptosporidium, can form spores that are resistant to environmental factors and can be transmitted through contaminated water or food.
It's important to note that not all microorganisms form spores, and some spores are beneficial, while others are harmful.
