The Timpe and Runyon classification of nontuberculous mycobacteria based on the rate of growth, production of yellow pigment and whether this pigment was produced in the dark or only after exposure to light.[1]
It was introduced by Ernest Runyon in 1959.[2]
On these bases, the nontuberculous mycobacteria are divided into four groups:
