Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Scientific Name Enterococcus
Comments 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.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
