muribaculaceae muribaculaceae muribaculaceae, previously known as s24-7, is a family of bacteria within the order bacteroidales. muribaculaceae is a prevalent and abundant bacterial component of the gut microbiome of mammals. muribaculaceae scientific classification domain: bacteria phylum: bacteroidota class: bacteroidia order: bacteroidales family: muribaculaceaelagkouvardos et al. 2019 genera "candidatus amyloruptor" corrig. hinsu et al. 2019 duncaniella lagkouvardos et al. 2019 "heminiphilus" park et al. 2021 muribaculum lagkouvardos et al. 2016 paramuribaculum lagkouvardos et al. 2019 "sodaliphilus" wylensek et al. 2020 in 2016, family s24-7 was studied in-depth and given the name "homeothermaceae", however, as no isolates were provided as type material, the name was not validated. the first isolated member of this family was muribaculum intestinale as part of the mouse intestinal bacterial collection (mibc) in 2016. however, validation of the family only occurred in 2019 after detailed analysis of this family, along with description of duncaniella and paramuribaculum, two additional genera within this family. in a recent study on mice, members of the family muribaculaceae were shown to be major utilisers of mucus-derived monosaccharides in the gut.
