Transduction in mycobacterium smegmatis

SEVERAL people have studied lysogeny and lysogenic conversion in the advanced prokaryote, Mycobacterium1-3, and presented evidence for reciprocal genetic exchange from the lysogenic to the non-lysogenic state. Biochemical and physiological changes induced by lysogenization of M. phlei with mycobacteriophage B2 have been demonstrated by Juhasz4. We wish to report the isolation of a mycobacteriophage capable of mediating transduction in Mycobacterium smegmatis strain SN2, thus providing an opportunity to study the genetics of mycobacteria.
