Summary
Streptococcus intermedius, a common oral bacterium, can cause liver abscesses. This case highlights the importance of considering this pathogen in patients with unexplained abdominal symptoms and liver cysts.
Area of Science:
- Microbiology
- Infectious Diseases
- Hepatology
Background:
- Streptococcus intermedius is a Gram-positive bacterium.
- It is a commensal organism found in the oral cavity, upper respiratory, urogenital, and gastrointestinal tracts.
- It is also found in human feces and is the dominant species in subgingival plaque.
Observation:
- A 50-year-old man presented with prolonged abdominal pain, nausea, vomiting, diarrhea, and fever.
- A computed tomography (CT) scan revealed multiple liver cysts.
- Intravenous antibiotics and fluids were initiated.
Findings:
- Fluid from two liver abscesses was cultured.
- The cultures identified Streptococcus intermedius as the causative agent.
Implications:
- This case underscores the potential of Streptococcus intermedius to cause serious intra-abdominal infections, such as liver abscesses.
- Early recognition and appropriate antibiotic therapy are crucial for managing such infections.
- Further research may elucidate the specific mechanisms by which this bacterium leads to hepatic pathology.

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
