IS INTRO & HISTORY Flashcards
It can be defined as the study of a host’s reactions when foreign substances are introduced into the body.
IMMUNOLOGY
It is the study of the immune system, including its responses to microbial pathogens and damaged tissues and its role in disease.
IMMUNOLOGY
It is the branch of biomedical science that deals with the response of an organism to antigenic challenge and its recognition of what is self and what is not.

which involved the exposing of healthy patients
to the material from the lesions caused by the
disease was introduced by ________.

17th Century: 1670
- The wife of the British ambassador to Constantinople, observed the positive effects of variolation on the native population and had the technique performed on her own children.
Lady Mary Wortley Montagu
- a farmer, variolated his wife with the vaccinia virus obtained from “farmer Elford of Chittenhall, near Yetminster.”
- First record of anyone using vaccinia virus to “protect” against smallpox.
Benjamin Jesty
- He developed a vaccine for smallpox. _____ inoculated a 8-year old boy by named James Phipps with material obtained from a cowpox lesion. The results were conclusive but were met with great resistance by the Church.
Edward Jenner
- a German physiologist first came up with physio-chemical explanation of life and provided the explanation of yeast multiplication in fermentation.
Theodore Schwann
- a French physicist confirmed the role of yeast in fermentation.
Charles Cagniard Latour
- a German physician, pathologist, and anatomist came up with the concept of germ theory of disease.
JACOB HENLE
- He stated the idea that not only animal but also human diseases are caused by other living micro-organisms.
AGOSTINO BASSI
- a Hungarian physician discovered that the incidence of puerperal fever (also known as “childbed fever”) could be drastically cut by the use of hand disinfection in obstetrical clinics.
IGNAS SEMMELWEIS
- The germ theory of disease was proposed.
However, evidences are still not enough to prove that microorganisms can cause several diseases. Confirmation of the role of microbes in
fermentation.
19th Century: 1860’s - GERM THEORY
- a German biologist explained that in an organism’s immune system, phagocytosis process occurs where certain foreign microorganisms (such as amoeba) attach to the cell surface either to destroy it or feed on it.
ERNST HAECKEL
- He practice aseptic technique in surgery using
carbolic acid. This method has greatly improved
surgical practice specially in reducing infections
and complications as a result of contaminations.
JOSEPH LISTER
- a German microbiologist published the work on anthrax.
ROBERT KOCH
- a German physician demonstrated that mast cells (a type of white blood cells) is an essential part of the immune and neuroimmune systems.
PAUL EHRLICH
- The germ theory of disease was finally postulated by ________.
- This theory confirmed that some diseases are
indeed caused by micro-organisms.
LOUIS PASTEUR
- During this period, theory of using the live
bacterial virulence culture in the vaccines could
act as an immunity for chicken cholera and
anthrax was proposed.
19th Century: 1880 - VACCINES
- ______ vaccinated 24 sheep, 1 goat, and 6 cows with five drops of the living attenuated anthrax bacillus.
- On May 17, he inoculated all of the animals with a less attenuated strain.
- On May 31, all of the animals received viable
virulent anthrax bacilli.
LOUIS PASTEUR
- Who isolated the bacterium Mycobacterium
tuberculosis, and as its name suggests, the
causative agent of tuberculosis. - He discovered the bacterial origin of anthrax, the bacterium Bacillus anthracis.
ROBERT KOCH
- Identification of antibodies which responsible for immunity that allows to neutralize microbial toxin.
EMIL VON BEHRING AND PAUL EHRLICH
- He discovered the method in order to treat germ- borne diseases like tuberculosis, anthrax, and cholera.
- In honor of Jenner’s prior discover of smallpox
vaccine, _____ called his treatment vaccination.
LOUIS PASTEUR
He also developed the process now known as
pasteurization. In this process, liquid is boiled and then cooled in order to kill the bacteria that cause the souring of milk and other beverages.
LOUIS PASTEUR
- an American microbiologist, demonstrated that heat actually killed cultures of chicken cholera bacillus and was also effective in protection from cholera. This proved that the micro-organisms did not have to be viable to induce the protection.
THEOBOLD SMITH
- They discovered the diphtheria toxin.
EMI ROUX AND ALEXANDRE YERSIN
- They demonstrated the presence of anti-toxin in the blood of individuals recovering from diphtheria.
EMIL VON BEHRING AND KITASATO SHIBASABURO
- ________ was the first to use this antiserum in treating active disease.
VON BEHRING
- He demonstrated the cutaneous hypersensitivity.
ROBERT KOCH
- He provided the very first concrete evidence for the existence of a virus.
- He discovered that tobacco mosaic disease is
caused by a virus which is a non-bacterial
infectious agent.
DMITRI IWANOWSKI
- an American cancer researcher and bone
surgeon discovered a toxin (named after him – _____’s Toxins) which is a combination of live
bacteria and bacterial lysates to treat tumors.
WILLIAM COLEY
- Who discovered bacteriolysis and it became
known as the ______ Phenomenon. - He found that live cholera bacteria could be
injected without ill effects into guinea pigs
previously immunized against cholera.
RICHARD PFEIFFER
- Immunology was preoccupied with the definition of the cellular (___________’s phagocytosis theory) as opposed to the humoral basis of bactericidal defense.
- “Cellularists” believed that phagocytes, rather than antibodies, played the leading role in immunity.
ELIE METCHNIKOFF
- a Belgian immunologist and microbiologist
described an antibacterial, heat-labile serum
component.
JULES BORDET
- He came up with antibody formation theory which states that a specific kind of cell can induce the formation of several antibodies.

- He discovered the 3 different blood type groups: A, B, and O. He also discovered that when mixed, blood of different blood type groups will begin to agglutinate (clump together).
KARL LANDSTEINER
They observed the Immediate hypersensitivity
anaphylaxis, or more commonly known as “allergies”.
- They observed that people when exposed to
allergens (things that trigger the allergy), are likely to develop the immune reaction.
CHARLES RICHET AND PAUL PORTIER
- He uncovered a type of hypersensitivity reaction wherein antigens (foreign substances that trigger an immune response) tend to deposit in the walls of blood vessels, heart, and kidney.
- “______ reaction”
NICOLAS MAURICE ARTHUS
- A natural process of targeting pathogens like
bacteria for destruction, was discovered. - This process is done by body cells known as
________.
OPSONIZATION ; phagocytes
- They discovered a “serum sickness” allergy.
- It happens when the body reacts to certain
drugs that contain proteins that instead of
aiding in treatment, induces an adverse
reaction.
