DNA base composition analyses on 35 Gram negative yellow pigmented rods indicated two distinct groups. The larger contained 29 strains with G + C contents of between 30.8 and 39.5% and comprise 19 non-gliding, atlagellate strains and 10 gliding strains. The smaller, a heterogenous collection of six strains, had G + C contents in the 5 1.4-63% range.A TAXONOMIC study on flavobacteria and related Gram negative yellow pigmented rods (Hayes 1975) has delineated a number of distinct phena and the present communication reports on the DNA base composition of strains representing these phena.
