Eggerthella is a bacterial genus of Actinomycetota, in the family Coriobacteriaceae. Members of this genus are anaerobic, non-sporulating, non-motile, Gram-positive bacilli that grow singly, as pairs, or in short chains. They are found in the human colon and feces and have been implicated as a cause of ulcerative colitis, liver and anal abscesses and systemic bacteremia.[2][3]

The type strain for this genus, Eggerthella lenta, was known as Eubacterium lentum prior to 1999.[4][5] The genus is named for Arnold Eggerth, who first described the organism in 1935.[6]
Eggerthella has not been characterized well because of identification difficulties. It is an emerging pathogen that is likely to be studied and recognized more in years to come. It has a tendency to cause disease that spreads throughout the body.[7]
