title: Acute acalculous cholecystitis complicated with peritonitis caused by Lactobacillus plantarum.
abstract: Lactobacillus spp. rarely causes human disease. We report a case of a 57-year-old man with non-insulin-dependent diabetes and vascular disease admitted to our hospital with severe abdominal pain and fever. Signs of peritonitis were found upon examination. The patient underwent surgery, and a diagnosis of perforated cholecystitis with purulent peritonitis was made intra-operatively. A cholecystectomy was performed, and therapy with imipenem was initiated. Lactobacillus plantarum was isolated from bile and peritoneal fluid cultures 2 days later. The patient recovered well and was discharged on post-operative day 16 after 14 days of treatment with imipenem. To our knowledge, this is the second case reported of acute cholecystitis caused by Lactobacillus spp. This organism should be considered as a cause of biliary infections, especially in patients with underlying diseases. Correct identification is often difficult, but it is very important because these organisms are usually resistant to vancomycin and other antibiotics.
