agents that invade
the body and cause diseases.
List and describe the 5
main pathogens.
Virus – tiny; survive and replicate only
inside living cells;
can’t be killed (has to run its course)
organisms that absorb and use the
nutrients of living or dead organisms
single celled; larger than bacteria
Malaria: Spread by mosquito bites
Feed off
of other
living
things
(Lice)
What are the
4 ways
infectious
diseases
can be
spread?
Describe how
each of the
following
diseases are
treated:
medicine (antibiotics) are used to slow or
kill the growth of bacteria. You must

anti-fungal cream (athletes foot)
Good hygiene is the best
preventative measure;
other medications require prescription
prevention best, for ex. don’t share
brushes, use medicated shampoo, etc.

What is
?
~ It is the body’s second line

The inflammatory response shows
that body is attacking pathogens.
5. If a pathogen gets past the physical
barriers, what system kicks in to

antibodies that travel through
the lymphatic system to fight the
pathogens.
