Which of the following methods used to enumerate cells often requires specialized staining to observe non-pigmented bacteria?
A) spectrophotometry/turbidity
B) spread-plating
C) microscopy
D) spread-plating, turbidity, and microscopy

Question

Quizplus · Accepted Answer

While all of the methods listed can be used to enumerate cells, only microscopy requires specialized staining techniques to observe non-pigmented bacteria. Spectrophotometry/turbidity measures the turbidity of a liquid culture, spread-plating counts colony-forming units on an agar plate, and microscopy can visualize cells directly but may require staining to observe certain features.
