Spontaneous bacterial peritonitis (SBP) is a common complication in patients with cirrhosis of the liver. The organisms most commonly involved in this infection are gram-negative bacteria like Escherichia coli and Klebsiella pneumoniae, and gram-positive bacteria like Streptococcus pneumoniae and Staphylococcus aureus. Listeria monocytogenes is an uncommon gram-positive bacillus implicated in infections in neonates, pregnant females, the elderly, and immunocompromised patients. Listeria monocytogene-induced SBP is rare, with less than 40 cases reported in the medical literature. Monobacterial non-neutrocytic bacterascites (MNB) is a variant of SBP, where the ascitic fluid culture is positive but the ascitic neutrophil count is less than 250/mm3. Forty percent of these patients will subsequently have SBP. Only 2 cases of MNB from L monocytogenes have previously been reported. We report a case of MNB in a patient with cirrhosis whose ascitic neutrophil count was 164/mm', but Gram stain and microbiologic culture showed the growth of L monocytogenes.
