  • ❗ Caulobacter crescentus is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Caulobacter.

  • 🧍 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.
