Spontaneous bacterial peritonitis due to Brucella melitensis

Area of Science:

• Infectious Diseases
• Hepatology
• Microbiology

Background:

• Brucellosis is a zoonotic infection with diverse clinical manifestations.
• Spontaneous bacterial peritonitis (SBP) is typically associated with liver cirrhosis.
• Peritonitis as a complication of brucellosis is exceptionally uncommon.

Observation:

• A patient with known cirrhosis presented with symptoms suggestive of peritonitis.
• Blood and ascitic fluid cultures were obtained for diagnostic evaluation.
• The patient's clinical presentation and laboratory results indicated an infectious process.

Findings:

• Blood and ascitic fluid cultures confirmed the presence of Brucella melitensis.
• This represents a rare instance of spontaneous bacterial peritonitis caused by Brucella species.
• The causative agent, Brucella melitensis, was identified in both blood and peritoneal fluid.

Implications:

• Highlights the importance of considering Brucella in the differential diagnosis of SBP, especially in endemic areas.
• Suggests that Brucella infection can lead to severe intra-abdominal complications like peritonitis in cirrhotic patients.
• Underscores the need for broad-spectrum microbiological investigation in patients with cirrhosis and peritonitis.
