causation of Diseases Flashcards
what was the miasma theory
theory that diseases were caused by “bad air” emanating from decaying organic matter
what theory for disease paved the way for sanitation measures
miasma theory
what is the humorism theory
disease is a result of imbalance of 4 vital fluids(humors): yellow bile, black bile, phlegm, and blood
how did humorism try to treat diseases
patient care over diagnoses
diet, exercise, etc
who invented humorism and is known as the “father of medicine”
hippocrates
what was the theory of contagion
diseases were caused by rapidly multiplying minute bodies that transferred from infector to infected
what ways did girolamo fracastoro believe caused transfer of diseases
direct contact
by carriers such as clothes
through the air
which scientists performed expiriments that proved Girolamo Fracastoro’s theory of contagion
louis pasteur and robert koch
who invented the first microscope? how?
Antonie Van Leeuwenhoek. grinding class to make a magnifying lense
what discoveries were made with the invention of the microscope
bacteria
sperm cells
blood cells
what is the theory of spontaneous generation, what caused this theory
theory that life arose from non living material. bread left out developed fungus
what experiment did Francesco Redi run to disprove the spontaneous generation theory
he put a piece of meat in 3 jars (one open, one covered with gauze, and one airtight). to see which one would develop maggots
what experiment did Lazzaro Spallanzani run to disprove the theory of spontaneous generation
boiled 2 flaskes of broth, left one open and sealed the other to see which would have growth.
what did scientists claim in support of the theory of spontaneous generation after Redi and Spallanzani’s experiments
that air was needed to create life from a nonliving thing
what is the germ theory? who invented it?
theory that infectious diseases are caused by microbes or “germs” invented by Louis Pasteur
what is pasteurization
process for killing germs by boiling something then coiling it down
what experiment dis Pasteur run to disprove the theory of spontaneous generation
similar to spallanzani’s but using flasks with bent necks which allowed air in but trapped microorganisms in the curves
what are Koch’s Postulates
1). a particular microbe must be found in all cases of disease and in no healthy specimens
2). the microbe must be isolated from diseased and grown in the lab
3). the same disease must be produced when lab grown microbes are inoculated into a healthy subject
4). the same microbe must be recovered from the experimentally infected species and regrown in lab
what allowed Koch to have a big breakthrough in his study of microbes
staining microbes with dye to photograph them under a microscope
who used carbolic acid to disinfect wounds and surgical areas(HINT: its not lady Belle ): )
Joseph Lister
6 major pathogens(smallest to largest)
prions
viruses
bacteria
fungi
protozoa
helminths
pathogen definition
biological agent or organism that causes disease or illness to the host
3 diseases caused by prions
Kuru
Mad cow disease
chronic wasting disease
T/F viruses can be viewed under a normal microscope
FALSE. they can only be viewed by electron microscope
