Understanding Microbes and Disease

By: Shirley Grimsley

Rationale

Microbes are a part of our lives every day. Some of them are good for us, some of them are harmful, and some of them are deadly.

We need to understand the role microbes play in our lives and how to prevent diseases that are associated with them.

CLASSIFYING MICROBES

Study the pictures of microbes provide by the teacher. With

your group, decide on a way to classify the microbes pictured.

Answer the following questions with your group.

  How did you classify the microbes? Show which microbes fit into each category and explain how they fit.

If you had to classify the microbes in a different way, how would you group them?

Some Microbes in Our World

Protists Bacteria VirusEntamoeba histolytica

StreptococcusAIDS

Many microbes in our world cause sickness and disease in animals and plants.

Protists

Entamoeba histolytica Causes dysentery, a severe form of

amebiasis associated with stomach pain, bloody stools, and fever.

•Plasmodium, a one-celled parasite transmitted by a mosquito.

•Causes malaria, which causes flu-like symptoms and intestinal problems.

Plasmodium attacking a red blood cell

Bacteria

Streptococcus Bacterium Causes strep throat, a painful

sore throat and fever.

Mycobacterium tuberculosis Causes tuberculosis, a highly

contagious respiratory disease.

Viruses

Orthomyxoviridae – Influenza virus Causes the flu, which is a respiratory

infection that often causes the infected person to have a fever, headache, and body aches.

Retroviridae - HIV (Human Immunodeficiency Virus)

Causes Acquired Immunodeficiency Syndrome (AIDS), which is a deadly disease

that attacks the human immune system.

How can you prevent the spread of diseases caused by microbes?

#1 - Wash your hands.

Top 5 ways to help prevent the spread of disease:

#2 - Keep surfaces clean and disinfected.

#5 - Use antibiotics correctly.

#3 - Use care when preparing and handling food.

#4 - Get immunized.
