Enterococcus avium
Enterococcus avium
Enterococcus avium (pronunciation: en-ter-o-co-cus a-vi-um) is a species of Enterococcus, a genus of lactic acid bacteria.
Etymology
The name Enterococcus avium is derived from the Greek words enteron meaning intestine, kokkos meaning grain or berry, and avium meaning of birds. This is because the bacteria was first isolated from the intestines of birds.
Description
Enterococcus avium is a Gram-positive, non-spore-forming, facultative anaerobic bacterium. It is part of the normal intestinal flora of humans and animals, but can also be found in the environment, particularly in soil and water.
Pathogenicity
While Enterococcus avium is generally considered a commensal organism, it can cause opportunistic infections in humans, particularly in those with weakened immune systems. These infections can include endocarditis, urinary tract infections, and bacteremia.
Treatment
Treatment of Enterococcus avium infections can be challenging due to the organism's inherent resistance to many commonly used antibiotics. However, combinations of aminoglycosides and cell wall-active agents have been shown to be effective in some cases.
