Leukocyte analysis is useful for the differentiation of bacillary dysentery, demonstrating a preponderance of polymorphonuclear (PMN) leukocytes over mononuclear leukocytes. The PMN cells exhibit clear-cut ring nuclei with evidence of toxic necrosis of cells and degenerative changes. The absence of leukocytes does not rule out invasive bacterial diarrhea. If samples are collected too early in the acute phase of the disease, it may result in negative screens.
