Such infections include biliary tract infection, intra-abdominal abscess, spontaneous bacterial peritonitisendometritis, and salpingitis.

Enterococci are usually part of mixed aerobic and anaerobic flora.

Antimicrobial regimens with minimal in vitro antienterococcal activity are often effective in treating mixed infections; therefore, the pathogenicity of enterococci in this setting is questionable.

Antienterococcal bactericidal activity is recommended when blood culture results are positive for enterococci.

In more seriously ill patients, enterococcal infections have been associated with higher risk of treatment failure and mortality. Consider administering antibiotics with antienterococcal activity to immunocompromised patients at high risk for bacteremia, patients with peritonitis and valvular heart disease, patients with severe sepsis of abdominal origin who have recently received broad-spectrum antibiotics, and patients with persistent intra-abdominal fluid collections without clinical improvement.
