Kingdoms
• Scientists classify living organisms into 6 main groups called Kingdoms. These include:– Animals– Plants– Fungi– Protists– Bacteria– Archaea

Microbes
• Germ = microbe that causes disease.• Microbes cause most infectious diseases.• Microbes include Protists, Bacteria, Fungi, and
Viruses. Since viruses are not alive, they are not organisms. This is why we call them microbes and not microorganisms.

First 3 Kingdoms
• You are familiar with Animals and Plants.• The 3rd Kingdom is Fungi, and includes:– Mushrooms– Yeast– Mold

Protist• Protist is a single-celled microbe with a nucleus• Some cause illness but many are harmless.• Some Trypanosoma cause sleeping sickness.• Most Paramecium are harmless.• Some Amoeba cause digestive illness.

Bacteria/Archaea
• These are single-celled without a nucleus.• They are also the most common microbes and
are tiny (1000 could fit on the dot of an “i”).• Some cause diseases but some are helpful.• Without them nothing would decompose.• Some are important in food and drinks. Most
yogurt have “live and active yogurt cultures” made by fermentation of milk by bacteria.

Bacteria Types: Spheres
• Diplococci (pairs)– Pneumonia
• Staphylococci (cluster)– Skin infection
• Streptococci (chains)– Strep throat

Bacteria Types: Rods
• Bacilli (rods)– Upset stomach
• Mycobacteria (chains)– Tuberculosis

Bacteria Types: Others
• Vibrio (curved rod)– Cholera
• Spirilla (short spiral)– Decomposers
• Spirochete (long spiral)– Syphilis
• Actinomyces (branched chain)– Produce antibiotics

Virus Discovery• Virus was discovered in 1898, about 45 years
before they were seen. Diseased tobacco plants had no bacteria even though the disease was infectious. It was thought that the disease was caused by a tiny unseen microbe they called “virus” which means “poison” in Latin.
• Seen with electron microscopes in 1939, we now know they cause flu, colds, chickenpox, and AIDS.

Virus
• Microbe, with no cells.• Smallest, but not a living organism.• They have genetic material, but not in a nucleus.• They cannot grow or reproduce independently or
carry out life functions like respiration.• Instead they rely on cells of living organisms for
their reproduction.• They are non-living germs that cause disease so
we call them microbes not microorganisms.

1. Can a microbe NOT be helpful OR harmful?2. If you look through a microscope and see a
long organism with a round structure inside of it, is it a protist, bacterium, or virus?
3. What are some advantages of using highest microscope power? Low power advantages?
4. Why are viruses NOT microorganisms?
