What is "eggerthella"

Eggerthella is a bacterial genus of Actinobacteria, 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.

The type strain for this genus, Eggerthella lenta, was known as Eubacterium lentum prior to 1999. The genus is named for Arnold Eggerth, who first described the organism in 1935.
