<unk><unk><unk>  is a blood-borne infection caused by enteric organisms in 70% of cases (mono-microbial origin in 90% of cases). Aerobic gram-negative<unk> like Escherichia coli account for half of the cases. Gram-positive cocci Streptococcus species in 20% cases and enterococcus accounting for 5% of the cases. Staphylococcus aureus and Streptococcus salivarius are less frequent causes. Poly-microbial infection is mostly iatrogenic (more likely associated with abdominal paracentesis) or intra-abdominal source of infection. The cause of SBP is not definitively established, but is believed to involve hematogenous spread of organisms in patients with liver disease and altered portal circulation in  adults,<unk><unk><unk>  occurs in conjunction with cirrhosis of the liver and portal hypertension.
