Emerging Infectious Diseases Flashcards
List some beneficial roles that microbes play
- Synthesize vitamins to allow breakdown in our intestine
- break down wastes (yeast/moss/mold)
- Make oxygen
- turn inorganic molecules (o2/N) into organic compounds (nucleic acids)
- food production
- digestion and breakdown in people and animals
- Normal flora; protects us from more virulent microbes
why do cows rely on microbes for their digestion?
Because they dont have enzymes in their digestive system that break down cellulose, so they have many microbes in their “incubation” stomach that helps with breakdown.
True or False: Microbes and Humans are dependent on each other
TRUE
the natural evolution of microbe operates on it __________ not its ________
spreading capacity , ability to cause a disease
True or False: a well adapted microbe can live in its host without causing significant damage
TRUE
Many infectious diseases can be viewed as a ______ of microbe to adapt to its host
failure
Define an epidemic
disease that infects a large number of people at the same time
Differentiate between TB and Ebola
TB: significant disease which has been around for many years; causes chronic illness for >30 years and is less aggressive. Since of the prolonged illness, there is a higher chance of infecting other people
Ebola: extreme aggressive ; kills up to 90% of infected patients ; spreads randomly in different parts of the world at random times
Define a virulent microbe
a microbe that tends to cause severe and serious diseases
Pandemic are…
an epidemic that affects a large georgraphical area and has the potential to spread worldwide
TRUE OR FALSE: in the 1900’s, most scientists decided to focus more on infectious diseases and less on the causative factors such as; better sanitation, vaccines, antibiotics ect.
FALSE ; other way around :)
What did the US surgeon general say in 1969?
“time to close the book on infectious disease”
Why wont infectious diseases dissapear?
drug restraint strains: TB
outbreaks of exsisting strains: WNV, flu, monkey pox
new diseases: hiv/aids, SARS, MERS-COV, ebola
Explain the transmission of monkey pox..
GIANT GAMBIAN RAT (disease carried by imported african rats being used as pets) –> Prairie Dogs (disease spread to dogs captured in texas for pets :S ew…) —> HUMANS ( by being scratched or bitten by a gross ugly prairie dog)
Is small pox related to monkey pox?
yup.
