Liver Abscesses Caused by Streptococcus intermedius in an Immunocompromised Patient

Streptococcus intermedius is a Gram-positive bacterium that is part of the normal flora in the oral cavity, as well as in the upper respiratory, female urogenital, and gastrointestinal tracts. It may also be found in human feces and is the dominant species found in subgingival plaque. We present a case of a 50-year-old man who came to the emergency room with abdominal pain for weeks associated with nausea and vomiting, diarrhea, and fever. A computed tomography (CT) scan of the abdomen showed numerous cysts throughout the liver. The patient was started on intravenous (IV) antibiotics and fluid from two of the liver abscesses was obtained for culture.
