Immunology is the study of
physiological mechanisms that are used to defend the body from invasion by foreign or
infectious agents
In response to diseases caused by infectious agents, the body develops cells dedicated to defense,
these form...
the immune system
protective/adaptive immunity takes time to develop while ________________________ can
_________ _______- and cause disease
microorganisms can rapidly multiply
Immunity involves two responses:
1. Flexible but specific defenses of the adaptive immune response
2. Fixed defenses of the innate immune response
In adaptive =
B and T cells
(you MUST inheret something from your parents)

During vaccination we are given the strongest
primary adaptive immune response
microbes survive on ..... and release
-animal and plant products
-release digestive enzymes
microbes grow on

Some microbes are ________ and even __________ (ex:_____________)
some are harmless and helpful
ex: E. Coli
What is protecive immunity?
People who survive a specific infection become immune to it
To provide protective immunity, the immune system must first
engage the microorganism
What is the lag time between infection and protection?
around 7 days
True or false, the first infection is the most dangerous one
true
true or false, Disease is NOT prevented by prior exposure to an attenuated/killed infectious agent

Who recognized that only those who had recovered from the plague could nurse the sick without
becoming sick again?
430 BC- Thucydides
During the fifteenth century- Chinese and Turks used what to induce immunity? What is this
called?
dried crusts from smallpox pustules (inhaled or inserted into small cuts in the skin "variolation")
Origins of immunology attributed to who? What did he discover?
-Edward Jenner
-Discovered in 1796 that cowpox "vaccinia" protected from human smallpox
a pathogen is
Any organism with potential to cause disease
ex: Influenza and typhoid bacillus
Opportunistic pathogens cause disease if
the body's defenses are weakened or it gets into a part of the body it isn't normally found.
