ACTUAL QUESTIONS AND CORRECT
ANSWERS
An antibody produced by the human body that recognizes part of its own tissue is called what? -
CORRECT ANSWER auto-antibody
According to the article "New predictors of disease" what was the first disease that revealed auto-
antibodies could be useful for predicting later illness? - CORRECT ANSWER type I diabetes
According to the article
"New predictors of disease" what disease below is associated with auto-antibodies years before
symptoms arise? - CORRECT ANSWER celiac disease
According to the article "New predictors of disease" what disease below is associated with auto-
antibodies years before symptoms arise? - CORRECT ANSWER rheumatoid arthritis
As described in the article "New predictors of disease", the process of first identifying patients with
auto-immune disease, and then looking at old blood samples in storage to see if they produced auto-
antibodies before the disease produced symptoms is called what? - CORRECT
ANSWER retrospective study
In "Solving the mystery of MS" we learn that multiple sclerosis affects which tissue? - CORRECT
ANSWER brain and spinal cord
According to "Solving the mystery of MS" most scientists believe multiple sclerosis is caused by
auto-antibodies attacking the body's own protein that protects nerve cells, called what? - CORRECT
ANSWER myelin
In "Solving the mystery of MS" we learn that a controversial theory says that multiple sclerosis may
not be an auto-immune disease, but actually result from what type of problem? - CORRECT

, In "Taming lupus" we read that over half of patients with lupus are very sensitive to what? -
CORRECT ANSWER sun light
In "Taming Lupus" we read that most treatments strategies for lupus attempt to decrease what? -

About how many people does the Tuberculosis bacteria kill each year? - CORRECT
ANSWER 2 million
The E. coli bacteria that makes people sick, O157, uses what method to attach to intestinal cells? -
CORRECT ANSWER It injects its own receptor protein into the cell via a type 3 secretion
system.
What is a type 3 secretion system? - CORRECT ANSWER A set of proteins that works as a
'needle' and allows bacteria to inject their own proteins into a host cell.
How do type 3 secretion systems contribute to the ability of some bacteria to cause disease? -
CORRECT ANSWER They allow bacteria to control the inside workings of a cell while the
bacteria live happily on the outside
What is a likely reason for why bacteria developed secretion systems? - CORRECT
ANSWER To protect themselves against other organisms in the soil
What is one method bacteria use to avoid the adaptive immune system? - CORRECT
ANSWER they secrete enzymes that degrade antibodies
Which is NOT A REASON why Gram-negative bacteria are difficult to deal with? (choose the one
that is not correct) - CORRECT ANSWER Gram negative bacteria are resistant to the entire
Gram class of antibiotics
The more society uses an antibiotic, the more likely it is that bacteria will become resistant to the
drug. - CORRECT ANSWER True
Choose all statements that are TRUE about viruses: - CORRECT ANSWER -They contain
either RNA or DNA
