Spontaneous bacterial peritonitis caused by S. paratyphi A.

Spontaneous (primary) bacterial peritonitis (SBP) due to S. paratyphi A is relatively uncommon. Clinical manifestations of SBP vary widely from severe to slight or absent, necessitating laboratory investigation of ascitic fluid. The disease is confirmed by number of neutrophils > 250/mm3 associated with or without bacterial growth in ascitic fluid culture from diagnostic abdominal paracentesis. Here, we present a case of S. paratyphi A SBP occurring in a patient with chronic liver disease and portal hypertension.The patient was treated with intravenous cefotaxime with good clinical response.
