Question

Why is cfu more applicable to a culture of streptococcus than to a culture ofe. coli?

Answer 1

CFU stands for colony forming units. CFU is more applicable to a culture of streptococcus than to a culture of E.coli since the number of cells is not equal to the number of colonies. It is worth knowing that in the case of strep, the value of a CFU ranges between 30 and 300 whereas in the case of bacteria, one CFU represents a single bacterium.
