1275–1280. 1966.—A numerical study was made of 53 organisms, representing 12 genera of the family
Enterobacteriaceae
and 4 members of the genus
Aeromonas
. A total of 105 features was determined for each culture. Matching coefficients were computed, and the organisms were sorted into phenetic groups by use of the “highest-link” criterion. The genera
Enterobacter
(
Aerobacter
),
Escherichia, Citrobacter, Arizona, Shigella
, and
Salmonella
formed a single, large cluster with little or no evidence of subdivisions into tribes or genera.
Paracolobactrum
and
Klebsiella
were joined to the large group as subclusters. Members of the genera
Erwinia
and
Serratia
formed separate, distinct clusters related to the large group at a lower level of similarity. At a still lower level were appended
Aeromonas, Proteus, Providencia
, and some individual species from other genera. These organisms were no more closely related to one another than to the larger group.
