Abstract

Biochemical capabilities of bacterial and L-phase organisms of 15 bacterial strains were examined by using a variety of modified routine diagnostic biochemical tests. The results demonstrated that 13 of the tests examined were suitable for use with L-phase variants, that L-phase variants and revertant bacterial phase organisms retained diagnostically significant capabilities of the respective bacterial or L-phase organisms from which they were derived, and that the 13 biochemical tests could be usefully employed to relate a given L-phase variant to a given bacterial phase organism, to distinguish L-phase variants of different species, and to aid in the identification of nonreverting L-phase variants.
