CDC – DPDx – Amebiasis
However, the simplicity of the procedure makes it ideal for the laboratory that has only an occasional specimen to test. Recent studies indicate improved sensitivity and specificity of fecal antigen assays with the use of monoclonal antibodies which can distinguish between E. For an overview including prevention and control visit www. Image taken at x oil magnification and contributed by the Kansas Department of Health and Environment.
Three nuclei are visible in the focal plane black arrowsand the cyst contains a chromatoid body with typically blunted ends red arrow. Antigen detection may be useful as an adjunct to microscopic diagnosis in detecting parasites and can distinguish between pathogenic and nonpathogenic infections. Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. Antigen consists of a crude soluble extract of axenically cultured organisms. However, erthrophagocytosis is not typically observed on stained smears of E.
The majority of individuals with ameba infection are asymptomatic, but do pass cysts asymptomatic intraluminal amebiasis This is true for all cases of E. Life Cycle Cysts and trophozoites are passed in feces. Microscopic identification of cysts and trophozoites in the stool is the common method for diagnosing E.
In reference diagnosis laboratories, molecular analysis by PCR-based assays is the method of choice for discriminating between the pathogenic species E. Comparison of real-time PCR rationales for differential laboratory diagnosis of amebiasis. Figure contributed by Assist. The vacuolated cytoplasm seen in this image may be the result of less than optimal preservation. Excystation occurs in the small intestine and trophozoites are released, which migrate to the large intestine.

It has been established that the invasive and noninvasive forms represent two separate species, respectively E. Arch Med Res ; Because of the protection conferred by their walls, amibisae cysts can survive days to weeks in the external environment and are responsible for transmission. You may have already requested this item. The trophozoites multiply by binary fission and produce cystsand both stages are passed in the feces.
Remember me on this computer. In some patients the trophozoites invade the intestinal mucosa: DPDx is an education resource designed for health professionals and laboratory scientists. Please verify that you are not a robot. Antigen Detection Antigen detection may be useful as an adjunct to microscopic diagnosis in detecting parasites and to distinguish between pathogenic and nonpathogenic infections.
Differentiation is possible, but not always easy, based on morphologic characteristics of the cysts and trophozoites. J Clin Microbiol ; The specimen was preserved in poly-vinyl alcohol PVA and stained with trichrome.
