•Topic: 31.4 Immunity and
Technology
•Essential Question(s):
1. Under what
circumstances might
antibiotics NOT be useful
in treating a disease
caused by a pathogen?
2. Summarize: Write out
the steps that your
immune system takes
when you are
vaccinated.
KEY CONCEPT
Living in a clean
environment and building
immunity help keep a
person healthy.

31.4 Immunity and Technology
• The risk of getting sick increases when there are many
people in one area
31.4 Immunity and Technology
• How do we control the spread of disease?
Pg. 64
– Cleaning supplies
– Medicines
– Vaccines
– Technologies that help to prevent against sickness OR
treat people who are sick
31.4 Immunity and Technology
Many methods are used to control pathogens.
• Antibiotics and antiseptics cause pathogens to burst.
31.4 Immunity and Technology
• Antiseptics kill pathogens outside of the body.
– do not target specific pathogens
– examples include vinegar and soap
• Antibiotics kill pathogens inside the body.
– target one specific bacterium or fungus
– not effective against viruses
31.4 Immunity and Technology
• Antibiotics are over used and over prescribed!!!!!
– Leads to antibiotic resistance
31.4 Immunity and Technology
• Antibiotic resistance can cause medicines to become
ineffective.
– Some bacteria develop an immunity to antibiotics.
– These bacteria spread the gene, making the antibiotics
useless.
31.4 Immunity and Technology
• Vaccines also control pathogens and disease.
– given to prevent illness
– contain the antigen of a weakened pathogen
- (contains the dead, weakened, or inactivated pathogen)
31.4 Immunity and Technology
• Vaccination provides immunity.
– stimulates a specific
immune response
– causes memory
cells to be
produced
– allows immune
system to respond
quickly to infection
– has such a fast
response, a person
will not get sick
