C1 - LESSON 2: HISTORY AND FOUNDATION OF IMMUNOLOGY Flashcards
The discipline of immunology grew out of the observation that individuals who had (?) from certain infectious diseases were thereafter (?) from the disease.
recovered; protected
The Latin term (?), meaning “exempt,” is the source of the English word immunity, meaning the state of protection from infectious disease.
immunis
As early as (?), during the plague in Athens, (?) recorded that individuals who had previously contracted the disease recovered and he recognized their “immune” status.
430 BC; Thucydides
(?) - (?) developed a practice of inhaling powder made from (?) in order to produce protection against this dreaded disease.
1500s
Chinese
smallpox scabs
- practice of deliberately exposing an individual to material from smallpox lesions.
Variolation
In the 15th century, (?) were inserted with a pin into the skin.
powdered smallpox “crusts”
When this practice became popular in England, it was discouraged at first, partly because the practice of (?) occasionally killed or disfigured a patient.
inoculation
is generally considered to be the Father of Immunology.
Louis Pasteur
- Edward Jenner discovered a remarkable relationship between exposure to cowpox and immunity to smallpox.
1700s
- procedure of injecting cellular material.
Vaccination
the Latin word for “cow”
vacca
- phenomenon in which exposure to one agent produces protection against another agent.
Cross-immunity
, a key figure in the development of both microbiology and immunology, accidentally found that old cultures would not cause disease in chickens
Louis Pasteur
Subsequent injections of more virulent organisms had no effect on the (?) that had been previously exposed to the older cultures. In this manner, the first attenuated vaccine was discovered.
birds
- to make a pathogen less virulent through heat, aging or chemical means.
