Which of the following statements is a reason why Acid-Fast Bacteria resist the Gram stain
a) Because their cell wall architecture varies from both gram-negative and gram-positive bacteria.
b) Because they lack the peptidoglycan layer.
c) Because they have a thick peptidoglycan layer.
d) Because they have a thick layer of fatty acids.
You perform a Gram staining technique on two bacterial species and observe that
one is stained purple while the other is stained pink. Which of the following is
consistent with this observation?
a) The purple one is likely more resistant to penicillin
b) Both bacteria have a cell wall made of mycolic acid
c) Their peptidoglycan layers have the same thickness
d) They differ in the number of phospholipid membranes
e) One has a monolayer of phospholipids while the other has a bilayer of
phospholipids
When counting bacteria, the difference between the standard plate (STP) count
and a direct microscopic count is that STP counts the number of
.........
