Summary
A case of bacterial peritonitis caused by Streptococcus gallolyticus subsp. pasteurianus in Japan is reported. The patient recovered after antibiotic treatment for this rare abdominal infection.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Medicine
Background:
- Bacterial peritonitis is a serious abdominal infection.
- Streptococcus gallolyticus subsp. pasteurianus is a bacterium rarely implicated in peritonitis.
Observation:
- A 55-year-old man presented with sudden abdominal pain, inflammation, free air, and ascites.
- Emergency surgery revealed polymicrobial peritonitis.
Findings:
- Bacteriological examination of ascetic fluid identified Streptococcus gallolyticus subsp. pasteurianus, Escherichia coli, Citrobacter freundii, and Bacteroides thetaiotaomicron.
- The patient received flomoxef (FMOX) for 6 days and was discharged on hospital day 17.
Implications:
- This case represents the first reported instance of bacterial peritonitis due to S. gallolyticus subsp. pasteurianus in Japan.
- Highlights the importance of identifying causative agents in peritonitis for effective treatment.
- Contributes to the understanding of S. gallolyticus subsp. pasteurianus as a potential pathogen in intra-abdominal infections.

Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
