Deoxyribonucleic acid reassociation measurements revealed that 50 of 111 Jordan 1890 strains examined could be separated into 10 groups of genetically related organisms. The results of deoxyribonucleic acid relatedness studies and phenotypic comparisons suggested that five of these groups were hitherto undescribed species and that four others probably represented previous ly, but inadequately, described species. The tenth group, which included the type strain, represented the species sensu stricto. Our data show that and Schardinger 1905 are genetically and phenotypically distinct species. Thus, the phenotypic heterogeneity of the species sensu lato is not due to inherent variability of genetically related strains but rather is due to inclusion of genetically unrelated organisms in this taxon.
