Which class of cells most often contain extrachromosomal DNA found in plasmids?
Prokaryotic
What is the significance of the molecule that makes up the bilayer formed in the plasma membrane of
most bacterial and eukaryotic cells?
Phospholipids help maintain hydrophobic and hydrophilic environments.
Which microorganisms produce dermatophytes that can cause skin infections, such as athlete's foot and
ringworm?
Fungi
Which microorganisms can produce human pathogens that spread via microsporidia?

A patient recently had an outpatient surgical procedure. After a few days at home, they noticed swelling
and redness at their incision site. How would this infection be classified?
Iatrogenic
Which viral virulence factor requires adjustments to the influenza vaccine annually?
Antigenic variation
Which pair of enzymes are produced by some bacteria that causes the clotting of blood to protect the
bacteria in the bloodstream, then a digestion of the clots to allow the bacteria to spread?
Coagulase and kinase
How does coinfection of a single cell by multiple strains of a virus increase it's pathogenicity?
Coinfection provides the opportunity for an antigenic shift.
Canned food is heated and sealed in sterile containers to provide a longer shelf life and prevent
spoilage. Improper canning results in the growth of microorganisms, which may result in food containers
that swell and explode.
Which staining technique can be used to identify these microorganisms?
Endospore staining
A student in a lab has just completed an endospore stain of Bacillus anthracis and realized that heat was
not applied during the staining technique.
