title: Equivalence of mycobactins from Mycobacterium senegalense, Mycobacterium farcinogenes and Mycobacterium fortuitum.
abstract: Mycobactins were isolated from five strains designated Mycobacterium farcinogenes and a similar number designated Mycobacterium senegalense following growth under conditions of iron-limitation. These lipid-soluble iron-chelating compounds were characterized by a combination of thin-layer and high-performance liquid chromatography. The mycobactins from both the slow-growing M. farcinogenes and the rapidly-growing M. senegalense strains proved impossible to differentiate both from each other and from those produced by strains of Mycobacterium fortuitum, indicating a close relationship between all three species. However, Nocardia farcinica, previously implicated with the bovine farcy strains, produced a different mycobactin which was easily distinguished by thin-layer chromatography alone.
