What is epidemiology?
The study of when and where diseases occur and how they are transmitted in populations
Historically what did people believe caused contagion/disease?
"Evil" spirits
"Bad" thoughts or deeds
"Improper" living
Emotions and immunity have been shown to be related
Do a large or small percentage of bacteria, viruses, and fungi in the world cause disease?
Only a small percentage of the viruses, bacteria and fungi in the world cause disease
What positive uses/effects do bacteria have in our everyday lives?
Bacteria in intestines help blood vessels mature. Bacteria aids in decomposition, foods, and medicine.
Why is John Snow considered the Father of Epidemiology?
,He discovered that his hypothesis that germ-contaminated water was the source of cholera, rather than
particles in the air as believed previously. He was able to track the source of cholera back to the Broad
Street Pump in London.
What disease did John Snow study?
Cholera
What is the importance of the Broad Street Pump?
The Broad Street Pump was determined to be the source of cholera in London, and eventually led to the
discovery of water-borne illness.
Pathology
Study of disease
Etiology
Study of the cause of disease
Pathogenesis
Development of disease
Infection
Colonization of the body by pathogens
, Disease
An abnormal state in which the body is not functionally normal
Transient microbiota
May be present for days, weeks, or months.
Normal microbiota
Permanently colonize the host.
Symbiosis
The relationships between normal microbiota and the host.
What are two examples of permanent resident bacteria?
Escherichia coli (From food and environment)
Lactobacilli (First bacteria - from vagina during birth)
Viruses, bacteria, fungi protozoans, and prions can all be ________________________.
transient flora
Commensalism
One organism is benefited and the other is unaffected.
