Mycobacterium fortuitum subspecies acetamidolyticum, a new subspecies of Mycobacterium fortuitum.
Mycobacterium fortuitum subspecies acetamidolyticum is a new subspecies of M. fortuitum and has an intermediate growth rate. It is a nonphotochromogenic mycobacterium. It does not utilize glutamate but utilizes acetamide as a simultaneous nitrogen and carbon source. It is able to utilize acetate, malate, pyruvate, fumarate, glucose, fructose, and n-propanol as the sole sources of carbon in the presence of ammoniacal nitrogen, but does not utilize them in the presence of glutamate-nitrogen. It is easily differentiated from all rapidly growing mycobacteria by its inability to utilize glutamate as a simultaneous nitrogen and carbon source, and from all slowly growing mycobacteria by its capacity to utilize acetamide as a simultaneous nitrogen and carbon source. Its mycolic acid pattern is different from that of M. fortuitum. However, its deoxyribonucleic acid showed 94% relatedness with that of M. fortuitum. In view of the above findings, it has been designated as a new subspecies of M. fortuitum. The organism was isolated from sputum of a 56-year-old patient with lung disease and is considered to be a lung pathogen. The type strain is ATCC 35931 (NCH E11620).
