Caulobacter Henrici and Johnson 1935, genus. (Type genus of the order ¤ Caulobacterales Henrici and Johnson 1935 [Approved Lists 1980]; type genus of the suborder ¤ Caulobacterineae Breed et al. 1944 [Approved Lists 1980]; type genus of the family ¤ Caulobacteraceae Henrici and Johnson 1935 [Approved Lists 1980]).
Type species: ¤ Caulobacter vibrioides Henrici and Johnson 1935 (Approved Lists 1980).
Etymology: L. n. caulis, stalk; N.L. masc. bacter, rod; N.L. masc. n. Caulobacter, stalk(ed) rod.
Approved Lists reference: SKERMAN (V.B.D.), McGOWAN (V.) and SNEATH (P.H.A.) (editors): Approved Lists of Bacterial Names. Int. J. Syst. Bacteriol., 1980, 30, 225-420 (Approved Lists of Bacterial Names in IJSEM Online - Approved Lists of Bacterial Names Amended edition).
Original publication: HENRICI (A.T.) and JOHNSON (D.): Studies of Fresh water Bacteria. II. Stalked Bacteria, a new order of Schizomycetes. Journal of Bacteriology, 1935, 30, 61-92.

Note: The genus Caulobacter is polyphyletic and only one of the lineages of Caulobacter species can retain the generic name. Under Rules 39a and 39b, the generic name must be retained for the genus that includes the type species. The lack of a type culture for the type species (¤ Caulobacter vibrioides) complicates the decision.

¤ Caulobacter vibrioides Henrici and Johnson 1935 (Approved Lists 1980).

Note:
According to Abraham et al. 1999, Caulobacter crescentus Poindexter 1964 (Approved Lists 1980) is a later heterotypic synonym of ¤ Caulobacter vibrioides Henrici and Johnson 1935 (Approved Lists 1980).
Moore et al. (1978) [1] reported the DNA-DNA homology between the type strain Caulobacter vibrioides CB51 and the type strain Caulobacter crescentus CB2 to be 97%, but they did not formally propose Caulobacter crescentus to be synonymous with Caulobacter vibrioides.
Caulobacter crescentus could not be discerned clearly from Caulobacter vibrioides by a polyphasic approach [2] and, Abraham et al. (1999) formally propose that Caulobacter crescentus Poindexter 1964 (Approved Lists 1980) is a later heterotypic synonym of Caulobacter vibrioides Henrici and Johnson 1935 (Approved Lists 1980) [2].

(1978) [1] reported the DNA-DNA homology between the type strain Caulobacter vibrioides CB51 and the type strain Caulobacter crescentus CB2 to be 97%, but they did not formally propose Caulobacter crescentus to be synonymous with Caulobacter vibrioides. Caulobacter crescentus could not be discerned clearly from Caulobacter vibrioides by a polyphasic approach [2] and, Abraham et al. (1999) formally propose that Caulobacter crescentus Poindexter 1964 (Approved Lists 1980) is a later heterotypic synonym of Caulobacter vibrioides Henrici and Johnson 1935 (Approved Lists 1980) [2].
