What is the Optimum Culture Incubation Time for Most Mycobacteria

Question

What is the optimum culture incubation time for most mycobacteria associated with human disease?
A) 2 to 6 weeks
B) 1 to 2 weeks
C) 5 to 7 days
D) 3 to 5 days

Accepted Answer

Most mycobacteria associated with human disease require a longer incubation period compared to other bacteria. The optimum culture incubation time for them is 2 to 6 weeks, which allows for the slow growth rate of these bacteria. Shorter incubation times may result in false negatives.
