Abstract

Following iron-deficient growth, mycobactins and exochelins were isolated from 11 strains of (including type strains of the virulent H37Rv and avirulent H37Ra organisms) as well as from (one strain), BCG (two strains), (eight strains) and (one strain) but not from (one strain). The mycobactins from the tuberculosis group ( and ) were identical and could each be resolved into four compounds by thin-layer chromatography (TLC) and into several fractions by high-performance liquid chromatography, supporting previous claims that this group is a single taxon. Exochelins were all chloroform-soluble and showed no species specificity; no single exochelin was recognized by TLC that had not been previously seen in or a related species.
