Germs that make us sick

Every day we are in a battle. A battle against tiny organisms that would like to live on or inside of us. The good news, we have an amazing immune system that can destroy most of these invaders.

Most diseases are caused by four very small groups of organisms.

Let’s call them the four main germs,

  • Protozoa
  • Fungi
  • Bacteria
  • Viruses

Protozoa are single organisms that live in moist areas including water.

They are the reason why clean water is so important

They cause a host of diseases including

Malaria, giardia, sleeping sickness, nausea and impact up to a billion people annually.

The good news is that there are a  host of drugs to treat this illness including doxycycline.


can also cause disease Fungi are found in moist areas

A common example is a mold.

Mold is a fungus that grows in the form of multicellular filaments called hyphae.

Most fungi are not dangerous, but some types can be harmful to health and a couple are deadly.

One example you may be familiar with is athletes' foot.

Other diseases include mild fungal skin diseases that look like a rash, asthma or allergies and lung infections.

There are antifungal drugs that treat fungal infections by killing or stopping the growth of the fungus.

Viruses are very small and are basically a protein covering and genetic material. They need a host in order to reproduce and can cause all types of diseases.

I would imagine everyone watching this video has had a cold caused by a virus.

Other common diseases include

  • smallpox.
  • different types of flu.
  • measles
  • mumps
  • rubella
  • chickenpox

Viruses can be treated with a vaccine that trains your body to recognize the virus and then destroy it. For a viral illness, unfortunately, there is no medicine like an antibiotic or an antiviral medicine that will immediately kill the virus. You just treat the symptoms.


are single-celled microorganisms that thrive in many different types of environments. Some varieties live in extremes of cold or heat. Others make their home on your skin, in people's intestines, or in your blood where they help digest food. Most bacteria cause no harm to people, but there are exceptions.

Infections caused by bacteria include:

  • Strep throat
  • Tuberculosis
  • Most ear infections

Bacterial infections can be treated with antibiotics. There is a long list of antibiotics that fight and destroy the bacteria.
