We present a rare case of Listeria monocytogenes-induced spontaneous bacterial peritonitis (SBP) in cirrhosis. Examination of the patient's peritoneal fluid revealed an extremely high leukocyte count. We suspect, that the patient belongs to 1% of individuals in which Listeria monocytogenes is part of the intestinal flora. Cephalosporins as empiric antibiotics have a Listeria gap. A combination of aminopenicillin and aminoglycoside is recommended. Therefore, early microbiological diagnosis from ascites and blood is essential. Listeria should be considered as a rare cause of SBP, especially in case of very high leukocyte count in peritoneal fluid or lack of response to empiric therapy.
