31.4 Immunity and Technology 2.1 Atoms, Ions, and Molecules Set up Cornell Notes on pg. 65 • Topic: 31.4 Immunity and Technology • Essential Question(s): • Under what circumstances might antibiotics NOT be useful in treating a disease caused by a pathogen? • Summarize: Write out the steps that your immune system takes when you are vaccinated. KEY CONCEPTLiving in a clean environment and building immunity help keep a person healthy.
KEY CONCEPTLiving in a clean environment and building immunity help keep a person healthy.
The risk of getting sick increases when there are many people in one area
Pg. 64 • How do we control the spread of disease? • Cleaning supplies • Medicines • Vaccines • Technologies that help to prevent against sickness OR treat people who are sick
Many methods are used to control pathogens. • Antibiotics and antiseptics cause pathogens to burst.
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 • Antiseptics kill pathogens outside of the body.
Antibiotics are over used and over prescribed!!!!! • Leads to antibiotic resistance
Antibiotic resistance can cause medicines to become ineffective. • Some bacteria develop an immunity to antibiotics. • These bacteria spread the gene, making the antibiotics useless.
Vaccines also control pathogens and disease. • given to prevent illness • contain the antigen of a weakened pathogen • (contains the dead, weakened, or inactivated pathogen)
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
