Acute suppurative peritonitis

Acute suppurative peritonitis is classified by pathogenesis into primary peritonitis and secondary peritonitis. Primary peritonitis (also known as spontaneous peritonitis) has no primary focus within the abdominal cavity. The causative organisms are most commonly hemolytic streptococcus, pneumococcus, or Escherichia coli. Secondary peritonitis is the most common form of peritonitis, and perforation of hollow viscera within the abdominal cavity, or rupture of the arm or viscera caused by trauma, are the most common causes of acute secondary suppurative peritonitis.
