Mediterraneibacter is a genus of anaerobic bacteria in the family Lachnospiraceae.[1] Several species have been isolated from the human intestinal microbiota. The type species is Mediterraneibacter massiliensis,[2] which was originally isolated from a human stool sample. It was described as Gram-positive, non-motile, non-spore-forming and coccobacillary. It is catalase-positive and oxidase-negative.[2]
Taxonomy
The genus name combines a reference to the Mediterranean Sea with the Neo-Latin word bacter, meaning a rod. The specific epithet of the type species, massiliensis, refers to Marseille, whose Latin name is Massilia.[1]
Several species now assigned to Mediterraneibacter were originally classified in the genera Ruminococcus or Clostridium.[2] As of 2026, there are eight species with validly published and correct names.[1]
Ecology and significance
Mediterraneibacter gnavus, which is still widely discussed under its former name Ruminococcus gnavus, is a common member of the infant and adult human gut microbiota. Its interactions with the host vary among strains, and changes in its abundance have been associated with several intestinal and extra-intestinal disorders.[3]
