Laboratory Diagnosis of Amebiasis

Nowadays, in addition to this technique, typing by using monoclonal antibodies to surface antigens antigen-based hatk immunosorbent assay [ELISA] 7879, PCR-specific analysis 59,and restriction fragment length polymorphism ribotyping 41 have been of great value in understanding the epidemiology hatj these parasites and in investigating disease outbreaks. Laboratory methods for diagnosis of parasitic infections, p.

Application of the polymerase chain reaction PCR in the epidemiology of Entamoeba histolytica and Entamoeba dispar infections. Molecular biology-based diagnosis may become the technique of choice in the future because establishment of these protozoa in culture is still not a routine clinical laboratory process. This article has been cited by other articles in PMC. The prevalence of amebiasis varies with the population of individuals affected, differing between countries and between areas with different socioeconomic conditions.

Traditionally, IHA has been used as the standard serological test, but ELISA has been proposed as an alternative that is rapid, simple, and more sensitive.

These patients have normal rectosigmoidoscopic findings, without a history of blood in stool samples. Colonic findings in amebiasis have varied from thickening of the mucosa to flask-shaped ulceration mostly in the cecum or appendix or near the ascending colon, but rarely in the sigmoidorectal area The sensitivity of detection of specific antibodies to E.

Trophozoites move by extending creeping projections of cytoplasm, called pseudopodia, which pull them along.

Leonard Rogers designated emetine as the first effective treatment for amebiasis in Comparison of indirect fluorescent-antibody amoebic serology with counterimmunoelectrophoresis and indirect hemagglutination amoebic serologies. On the other hand, stool antigen detection tests offer a practical, sensitive, and specific way for the clinical laboratory to detect intestinal E.
