Corynebacterium freneyi
species of bacterium
Corynebacterium freneyi is a species of Gram-positive, non-motile, non-spore-forming, rod-shaped bacterium in the genus Corynebacterium. It was first described in 2001 by Renaud et al. based on α-glucosidase-positive strains related to Corynebacterium xerosis.
Taxonomy
C. freneyi was initially identified from clinical isolates that exhibited α-glucosidase activity and biochemical profiles similar to C. xerosis. However, molecular analyses, including 16S rRNA gene sequencing and restriction fragment length polymorphism (RFLP) of the 16S-23S rRNA intergenic spacer region, demonstrated that C. freneyi is a distinct species.
Clinical significance
Although initially considered a rare isolate, C. freneyi has been implicated in various clinical specimens, including those from the female genital tract. Its pathogenic potential remains under investigation, but it has been associated with bacteremia and prosthetic valve endocarditis in isolated cases.
Type strain
The type strain of C. freneyi is CCUG 45704 (= CIP 106767 = DSM 44506 = JCM 12104).
This brief starts where responsible research should: with the source description of “Corynebacterium freneyi” as species of bacterium. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bacterium. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q21262356. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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
