'''''Caulobacter''''' is a genus of Gram-negative bacteria in the class Alphaproteobacteria.<ref>{{cite journal|last=Poindexter|first=JS|journal=Microbiol. Mol. Biol. Rev. |date=Sep 1964|volume=28|issue=3|pages=231–95|pmid=14220656|pmc=441226|title=Biological Properties and Classification of the Caulobacter Group|doi=10.1128/mmbr.28.3.231-295.1964}}</ref> Its best-known member is ''Caulobacter crescentus'', an organism ubiquitous in freshwater lakes and rivers; many members of the genus are specialized to oligotrophic environments.
==Interactions with other organisms== ===Pathogenicity=== Although ''Caulobacter'' is not commonly appreciated as a cause of human diseases, ''Caulobacter'' isolates have been implicated in a number of cases of recurrent peritonitis in peritoneal dialysis patients.<ref>{{cite journal |display-authors=etal |last1=Justesen |first1=Ulrik |last2=Holt |first2=Hanne |title=Report of the First Human Case of Caulobacter sp.
