MIBO 3500 FINAL - SCOTT QUESTIONS & ANSWERS
What is a reservoir?
Animal, bird, or arthropod that normally harbors a pathogen without exhibiting the
disease
- these are important for the survival of the pathogen and source of infection
What is immunopathogenesis?
"friendly fire" by the immune system
- immune respose to a pathogen that is contributing cause of pathology and disease
How can infections effect microbiota? (hint: 3 effects)
- diarrhea reduces overall number of gut microbiota
- intestinal pathogens occupy host binding sites, altering avaliable nutrients
- inflammation benefits pathogens more than normal microbiota
What two forms of airborne transmission are most likely to propel droplets?
Sneezing and coughing
How many droplets are released during a cough, talking for 5 minutes, and singing for a
minute?
~3000
How many droplets are propelled during a sneeze?
>10,000 droplets
What is direct contact transmissioon?
Physical interaction between source and new host
What is indirect contact transmission?
Involves an intermediate (usally an inantmate object) --> ex: sharing eating utensils
What is adhesion and what is it used for?
Adhesion is a component of the microbial cell which attaches to the host cell receptors
What are some microbial adherance factors?
