Understanding Microbes
and Disease
By: Shirley Grimsley
Essential Question:
How can science help us to
understand the world around us?
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.
Many microbes in our world cause sickness
and disease in animals and plants.
Some
Microbes in
Our World
Entamoeba
Protists
histolytica
Streptococcus
Bacteria
AIDS
Virus
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, associated with flu-like
symptoms and intestinal problems.
Plasmodium attacking a red blood cell
Bacteria

Streptococcus Bacterium
Causes the strep throat, a
painful sore throat and fever.

Mycobacterium tuberculosis

Causes Tuberculosis, a highly
contagious respiratory disease.

Viruses


Retroviridae - HIV (Human Immunodeficiency
Virus)
Causes Acquired Immunodeficiency
Syndrome (AIDS), which is a deadly disease
that attacks the human immune system.


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.
How can you prevent the spread of
diseases caused by microbes?
Top 5 ways to help prevent the spread of disease:
#5 - Use antibiotics correctly.
#4 - Get immunized.
#3 - Use care when preparing and handling food.
#2 – Keep surfaces clean and disinfected.
And, #1 - Wash your hands.
