SUMMARY: The application of computer techniques to study a group of organisms comprising 83 strains of the genus and 38 strains belonging to the genera and is described. One hundred different features including vitamin, carbohydrate and nitrogen nutrition, antibiotic sensitivities, morphological and colonial characteristics, and infective attributes were used to determine the relationships between these organisms. Members of the genera and showed little affinity with the other species studied, or with each other. The results obtained for the genus indicate the need for major taxonomic changes. These changes would include: (1) the consolidation of and into a single species, ; (2) The consolidation of and and their inclusion as in the genus The creation of a new genus to contain strains of slow-growing root-nodule bacteria is also proposed.
