CoprococcusRANK: GenusTAXONOMY: Bacteria -> Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Lachnospiraceae -> Coprococcus OVERVIEW: 'Coprococcus' is a genus of anaerobic cocci which are part of the human fecal flora. Cocci that are Gram-stain-positive, nonmotile, and obligately anaerobic chemoorganotrophs. All species in the genus are isolated from human feces (Moore and Holdeman, 1974) but rarely isolated from human clinical specimens. Strains were originally isolated on an anaerobically sterilized rumen-fluid-glucose-cellobiose agar (Holdeman et al., 1977a) roll tube. However, pure cultured strains grow on anaerobically incubated blood agar plates (supplemented with brain heart infusion agar with 5% sheep blood). Cells may occur as pairs or chains of pairs. Cells of the some species are slightly elongated, in particular, when grown in medium containing fermentable carbohydrates. Fermentable carbohydrates are either required or are highly stimulatory for growth. Major fermentation products include butyric and acetic acids, with formic or propionic acid. Characteristics to differentiate species of the genus Coprococcus and biochemically closely related species of the Ruminococcus are given in Table 167. The genus phylogenetically belongs to family Lachnospiraceae and the phylogenetic position within the family is shown in Figure 1 (Ezaki et al., 1994; Rainey and Janssen, 1995; Willems and Collins, 1995a). In the family Lachnospiraceae, members of genus Coprococcus are phylogenetically closely related to anaerobic curved bacteria, genus Lachnospira This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072] A new study of two large groups of Europeans, led by Dr. Sara Vieira-Silva and Dr. Jeroen Raes from the Catholic University of Leuven (Belgium), has found new links between gut microbes and depression. Dialister and Coprococcus genera were reduced in people with depression. [Nat Microbiol. 2019. doi: 10.1038/s41564-018-0337-x]
