Description: English: This scanning electron micrograph (SEM) depicted numbers of bacteria, which were identified as being Gram-positive Enterococcus sp. bacteria. Previously identified as "Group D" Streptococcus organisms, the most clinically relevant of these bacteria are, E. faecalis, and E. faecium.Enterococcus spp. bacteria are notoriously linked as etiologic agents responsible for nosocomial, or "hospital-borne" illnesses, such as "Vancomycin Resistant Enterococci", or VRE infections. These organisms are "commensal" in nature, which means that they normally colonize the human digestive tract, and become pathogenic when their host becomes immunosuppressed, such as after a surgical procedure, or during a prolonged illness, or in immunocompromised individuals who might be undergoing chemotherapy, or in the case of AIDS patients.

Enterococcus spp est notoirement connu comme agents étiologiques responsables de maladies nosocomiales, avec notamment des souches résistantes à la vancomycine. Ces bactéries sont «commensales» dans la nature, occupant, de manière non-dominante le tractus digestif et génital de l'homme, et deviennent pathogènes chez les hôte immunodéprimés (par exemple après une intervention chirurgicale, lors d'une chimiothérapie, ou chez des malades du SIDA.
