Plesiomonas shigelloides in acute cholecystitis: a case report

Plesiomonas shigelloides was isolated as the sole pathogen from gallbladder bile and wall in a 58-year-old woman with acute cholecystitis. The patient developed an unusual postoperative complication characterized by culture-negative discharge from the wound in combination with extensive abdominal cellulitis and afebrility. Agglutinating antibodies to P. shigelloides were demonstrated in the serum of the patient by the microscopic Widal agglutination test.
