Fungi (singular fungus) are living organisms with about 144,000 known species. These include yeasts, molds, mildews, rusts, mushrooms, and smuts.

Fungi are the most common organisms on earth. They have great environmental and medical importance.

They are also organisms that look like fungi. Some of them are water molds, slime molds, etc. They don’t belong to the fungi kingdom but they are called fungi.

You can find fungi living freely in soil or water. Others form symbiotic or parasitic relationships with plants and animals.

Types of Fungi

There are three main groups of fungi and they are divided based on their life cycles. They are also divided based on the type of spores they produce, the arrangement of the spores, and the structure of their fruiting bodies.

The divisions are:

  • Multicellular filamentous molds
  • Macroscopic filamentous fungi (also known as mushrooms)
  • Singled cells microscopic yeasts

Fungi play different roles in the environment. Some fungi are pathogens (they cause diseases in the human body). Examples are yeasts and candida.

Yeast is used in cancer research. It is also one of the most used model organism for genetic studies. Candida causes infections in people who have a compromised immune system.

Fungi That Cause Diseases in Humans

In humans, pathogenic fungi enter the body through wounds in the skin. These wounds can be caused by insects, scratches, bruises, and cuts. There are about 300 known fungi that are pathogenic to man.

In the middle ages, a fungus called Claviceps purpurea caused ergotism, a disease that was prevalent in Northern Europe. It was common in people who consumed large quantities of rye-bread.

Other human diseases caused by fungi are:

  • Ringworm
  • Athlete’s foot
  • Coccidioidomycosis
  • Histoplasmosis
  • Aspergillosis
  • Yeast infection that affect the mouth, throat, reproductive organs, and colon. These yeast don’t cause diseases when they are in little amount in your body except they outnumber the beneficial bacteria (probiotics) in the gut.
  • Fungal nail infections
  • Fungal eye infection

Some medical procedures like drug therapies used to suppress the immune system after transplant and cancer treatment can weaken the immune system.

This makes the immune system unable to fight fungi pathogens. People with HIV/AIDS have weak defenses against fungi infection. Many deaths of AIDS patients are caused by fungi infections. The most common being that of Aspergillus fumigatus).

What You Need to Know About Common Fungi Infections

Athlete’s foot

This is a common fungal infection affecting the foot. This fungus grows in a warm and moist environment such as socks, locker rooms, sport equipment, and shoes.
