Numerical Survey of Some Bacterial Taxa

摘要: Focht, D. (Iowa State University, Ames), and W. R. Lockhart. Numerical survey of some bacterial taxa. J. Bacteriol. 90:1314–1319. 1965.—A numerical analysis was made 77 properties each 43 strains, representing 25 genera from 8 families in the orders Eubacteriales Pseudomonadales. Four major groups were found, related to one another at approximately same level similarity: (1) a large cluster containing subgroups (1a) Athiorhodaceae-Spirillaceae, (1b) Xanthomonas, (1c) “inactive” Micrococcaceae-Achromobacteraceae; (2) “active” Micrococcaceae Lactobacillaceae; (3) enterobacteria; (4) Aeromonas. There sharp distinction between branches 1a, 1c, 2. The composition essentially whether or not fermentation carbohydrates (28 characters) included analysis. Several individual notably, Bacillus subtilis, Leuconostoc mesenteroides, Pseudomonas aeruginosa, Erwinia amylovora, none groups, others (two species Proteus, Flavobacterium devorans, Lactobacillus casei) showed only minimal quantitative relationships with their groups. These results suggest that there may be significant variation levels similarity within microbial presently accorded equivalent taxonomic rank, present distinctions among taxa, particularly generic level, cannot confirmed on basis overall similarity.
