When an infection is suspected of being responsible for an illness but the responsible pathogen has not been identified, an empiric therapy is adopted. [35]
MMC impairment may be a result of post-infectious irritable bowel syndrome, drug use, or intestinal pseudo-obstruction among other causes. [17] There is an overlap in findings between tropical sprue , post-infectious irritable bowel syndrome and small intestinal bacterial overgrowth in the pathophysiology of the three conditions and also SIBO ...
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant.

The condition is usually caused by Gram-positive enteric commensal bacteria of the gut (). Clostridioides difficile is a species of Gram-positive bacteria that commonly causes severe diarrhea and other intestinal diseases when competing bacteria are wiped out by antibiotics, causing pseudomembranous colitis, whereas Clostridium septicum is responsible for most cases of neutropenic enterocolitis.
