RESUMO
Fregnan, G. B. (University of Wisconsin, Madison), D. W. Smith, and H. M. Randall. Biological and chemical studies on mycobacteria. Relationship of colony morphology to mycoside content for Mycobacterium kansasii and Mycobacterium fortuitum. J. Bacteriol. 82:517–527. 1961.—Using a suitable technique and an adequate medium it was possible to show a unique and uniform type of colony characteristic for Mycobacterium kansasii (photochromogen) and for Mycobacterium fortuitum strains freshly isolated either from patients, or from the soil, or kept in our stock culture collection for several years. New symbols have been proposed to represent these colony types. It was demonstrated that colony morphology is closely related to the specific mycoside present in a given strain; for example, M. kansasii strains showed in each instance colony type K and mycoside A, and M. fortuitum strains showed colony type F and mycoside F. Attention is called to the importance of the technique and the medium used.
