Abstract
A new species M. parafortuitum is described. A number of strains of the genus Mycobacterium Isolated from soil resembled M. fortuitum in their rapid growth, in their pattern of utilization of organic acids and in their pattern of amidase tests. However, these strains differed from M. fortuitum in the following points: they showed negative 3-day arylsulfatase test, they showed negative salicylate degradation and para-aminosalicylic acid (PAS) degradation, they did not utilize nitrite as sole nitrogen source and they formed acid from pentoses, arabinose, xylose, inositol and man-nitol. This group of strains has been named as M. parafortuitum sp.nov.
