The Role of Enteric Bacteria in Pyogenic Infections of the Abdominal Cavity
The mixed flora of the intestinal tract participates in infections Enteric Bacteria that originate from lesions of the bowel, such as appendicitis, cholangitis, diverticulitis, and perforation (from ulcerative colitis, ileitis, or carcinoma).
These may lead to subdiaphragmatic hepatic, and pelvic abscesses, which are frequent causes of fever of unknown origin in the patient recovering from abdominal surgery or trauma to this region.
Because enteric bacteria grow luxuriantly in both aerobic and anaerobic media and therefore are likely to predominate in cultures, their relative importance tends to ‘be exaggerated.
There is good reason to believe that anaerobic bacteria Bacteroides, Clostridia, and anaerobic streptococci— play more important roles in this kind of process. It should be pointed out here that a “fecal” odor of pus, though often ascribed to coliforms is doubtless caused by associated anaerobic bacteria'.
Anaerobic bacteria are usually present as mixtures of two or more species. They should be suspected when there is foul pus and when organisms can be visualized microscopically bait fail to grow under routine conditions.
