Abstract
A new species of rapidly growing, nonphotochromogenic mycobacteria, Mycobacterium moriokaense, is described. This taxon commonly occurs in the soil and may have been erroneously identified previously as Mycobacterium fortuitum. M. moriokaense can be differentiated from all previously described species of mycobacteria. The type strain is strain ATCC 43059 (= NCH E11715).
