On September 18, 2026, the JEMINI project published an article titled “Complete genome sequence of Subdoligranulum sp. strain DSM 23681 isolated from the cecum of a broiler chicken” in the journal Microbiology Resource Announcements.
Bacteria of the genus Subdoligranulum are frequently detected in the human gut microbiota and have been associated with a healthy cardiometabolic profile. To date, only one species of Subdoligranulum has been recognized: Subdoligranulum variabile. However, this species accounts for less than 1% of the total abundance of the genus in humans.
To assess the potential impact of the Subdoligranulum genus on host metabolism – for example, in the context of obesity – it is therefore essential to expand our understanding of this genus and its various species.
In this study, the authors isolated a Subdoligranulum strain from the cecum of a broiler chicken (strain ic1395 from the DSMZ23681 collection) and sequenced its genome. The resulting genome shows 96.8% similarity to S. variabile, indicating significant evolutionary divergence within this lineage.
