Rikenellaceae
Family of bacteria
From Wikipedia, the free encyclopedia
Rikenellaceae is a family of Gram-negative bacteria described by Noel R. Krieg in 2015. It contains nine genera, five of which are validly published by the International Code of Nomenclature of Prokaryotes.[2] Bacteria with 16S ribosomal RNA highly similar to the Rikenella genus, as compared to the larger taxonomic order Bacteroidales, are classified in this family.[1]

This family consists of non-motile, rod-shaped bacteria that are tolerant of bile. Most Rikenellaceae species have been identified in the gastrointestinal tract microbiomes of various animals.[3]
Bacteria of this taxonomic family are elevated in the gut microbiomes of mice that are leptin-resistant obese and diabetic.[4] However, Rikenellaceae bacteria are depleted in the gut microbiomes of obese American adults, leading to reduced synthesis of butyrate and disrupted metabolism.[5]
Gut microbiomes with elevated levels of Rikenellaceae bacteria are associated with lupus and Alzheimer's disease in mice and colorectal cancer in humans.[6][7][8]
