- A genus containing more than 40 species of anaerobic, nonsporeforming, nonmotile bacteria containing straight or curved Gram-positive rods which usually occur singly, in pairs, or in short chains. Usually these organisms attack carbohydrates. They may be pathogenic, and rarely are associated with intraabdominal sepsis in humans. The type species is E. limosum.- E. combesi a bacterial species from forest soil found in an area then called French West Africa; it is not pathogenic for guinea pig s or mice. Formerly called Cillobacterium combesi.- E. contortum a bacterial species found in cases of putrid, gangrenous appendicitis and in the intestines.- E. crispatum former name for Lactobacillus crispatus.- E. filamentosum former name for Clostridium ramosum.- E. lentum a bacterial species occurring commonly in the feces of normal persons; occasional cause of septicemia and nosocomial infections.- E. limosum a bacterial species that occurs in human feces and presumably in the feces of other warm-blooded animals. The type species of the genus.- E. minutum a bacterial species that occurs infrequently in the intestines of breast-fed infants; it was originally found in a case of infant diarrhea; it is pathogenic for mice.- E. moniliforme a bacterial species found rarely in the human respiratory system; it is pathogenic for guinea pig s, causing death in eight days. Formerly called Cillobacterium moniliforme.- E. parvum a bacterial species found in the large intestine of a horse and in a case of acute appendicitis; it occurs infrequently in the intestines of foals and of humans, and is not pathogenic for laboratory animals.- E. poeciloides a bacterial species infrequently found in human intestines; originally found in a case of intestinal occlusion; it is pathogenic for guinea pig s and rabbits.- E. pseudotortuosum a bacterial species found in a case of purulent, acute appendicitis; occurs uncommonly in the intestines.- E. quartum a bacterial species found in cases of infantile diarrhea; occurs in the intestines of children, but is rather uncommon.- E. tenue a bacterial species isolated from dog feces; its pathogenicity is unknown; formerly called Cillobacterium tenue.

* * *Eu·bac·te·ri·um (u″bak-teґre-əm) [eu- + Gr. baktērion small rod] a genus of bacteria of the family Eubacteriaceae, consisting of nonsporulating, gram-positive, anaerobic rod-shaped organisms found as saprophytes in soil and water. They are normal inhabitants of the skin and cavities of mammals and occasionally cause infections of soft tissues.
