A new species, Mycobacterium fallax, is described. A study of 22 strains showed that they form a homogeneous group with an internal phenotypic similarity value of 94.6 ± 4.1%. The colony morphology resembled that of Mycobacterium tuberculosis, with

Mycobacterium fallax was found to contain only α-mycolic acids which were separated by argentation chromatography into four fractions called M1 to M4 according to their decreasing Rf. The structures of these products were determined by chemical oxid
