Clinical Significance
The detection of a large amount of pus in feces aids in differentiating bacillary from amoebic colitis. In bacterial diarrhea, detection of fecal leukocytes may help to distinguish between invasive (Salmonella, Shigella, and Campylobacter) and toxigenic (Vibrio cholerae, toxigenic E. coli, Closttridium difficile) mechanisms. Many leukocytes suggest that diarrhea is due to an invasive organism. Patients with chronic ulcerative colitis and chronic bacillary dystentery frequently pass large amounts of pus. This also occurs in patients with localized abscesses or fistulas of the sigmoid colon, rectum or anus.
