A rare and unusual cause of Vibrio cholerae non-O1, non-O139 causing spontaneous peritonitis in a patient with cirrhosis.

Spontaneous bacterial peritonitis caused by Vibrio cholerae non-O1/ non-O139 is a rare phenomenon. V. cholerae is known as a common aetiology of epidemic diarrheal disease and rarely causes extra-gastrointestinal infections. In this report, a 52-year-old man presented to our hospital with a clinical scenario for chronic liver cirrhosis with low grade fever and loose stools. V. cholerae was isolated from peritoneal fluid culture, which was further confirmed as non-O1/ non-O139 strain by multiplex polymerase chain reaction. The patient was successfully treated with antimicrobial therapy and peritoneal drainage. This case represents the first isolation of V. cholerae non-O1/ non-O139 strain from peritoneal fluid.
