The genus is named for Arnold Eggerth, who first described the organism in 1935.
''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.
