Roseomonas rosea
species of Alphaproteobacteria
Roseomonas rosea (formerly Muricoccus roseus) is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pink-colored bacteria. It was first isolated from a children's day care center in 1995. Further work on the isolate led to the proposal of a new genus and species, Muricoccus roseus in 2003. Further work on M. roseus found that the species belonged in the genus Roseomonas, and also led to Teichococcus ludipueritiae being reclassified as Roseomonas ludipueritiae in 2009. The new name for the species is Roseomonas rosea. The species name is derived from Latin rosea (pink), referring to the pink color the bacterial colonies will form, which is also a present in most Roseomonas species.
The optimum growth temperature for R. rosea is 30 °C, but can grow in the 15-45 °C range.
Begin with the source’s own compact description: “Roseomonas rosea” is species of Alphaproteobacteria. The dossier treats that line as a proposition to test through Roseomonas, rosea and species, not as a finished interpretation.
Why this record matters
The phrase “species of Alphaproteobacteria” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 1, 2025. The linked authority identifier is Q26282345. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995, 2003 and 2009.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
