MICROBIO 303 Exam queries and
answers graded A+
Microbiology - ANS✅✅The study of microbial world
Microorganism/ Microbe - ANS✅✅Any organism too small to see with the naked eye
How many pounds of microorganisms does the body account for - ANS✅✅2- 6lbs
Microbes play defense - ANS✅✅The take up space and produce anti microbial compounds
How do microbes boost the immune system - ANS✅✅They stimulate immune system cells to
divide
How do microbes protect s from allergies and auto immune diseases - ANS✅✅The train our
immune system
Old friends hypothesis - ANS✅✅early exposure helps the immune system learn to distinguish
"friendly" microbes from those that can cause severe disease
How do microbes help keep us slim - ANS✅✅Make nutrients available, help with digestion and
ferment food, Produce chemicals to stimulate metabolic rates
Microbes detoxify - ANS✅✅Absorb and degrade toxic compounds
All microorganisms host what microbes - ANS✅✅Symbiotic microbes
What rate has decreased due to infectious disease over the last 100 years - ANS✅✅Death Rate
Germ theory - ANS✅✅the theory that infectious diseases are caused by certain microbes
, 1918 Influenza Pandemic - ANS✅✅changed from a epidemic and spread over an entire world
killing around 20 million in many areas around the world

Emerging infectious diseases - ANS✅✅Diseases that are new, increasing in incidence, or showing a
potential to increase in the near future
Urban Sprawl - ANS✅✅The process of urban areas expanding outwards, usually in the form of
suburbs, and developing over fertile agricultural land.
Factors associated with emerging diseas - ANS✅✅Decline of vaccinations
Changing lifestyle
Pathogens can become resistant
Increased travel and immigration
Critical Mass depends on R0 - reproductive number - ANS✅✅How many susceptible hosts become
infected from a single infected host
As R0 increases, the critical mass increases
