Of 21 clinically suspected cases of ALA investigated, all could be detected by CIE and IHA, with good correlation between all the tests, and showed a high degree of sensitivity. It consists of an infective cyst stage and a multiplying trophozoite stage. Antibody Detection Most people with intestinal amebic infection in areas of endemicity have been exposed to E.

Laboratory Diagnosis of Amebiasis

Asymptoatic inflammatory bowel disease with special reference to ulcerative colitis in apparently healthy persons. Diamond’s first axenic culture of E. Worldwide, amebiasis is the third most common cause of death due to parasitic infection after malaria and schistosomiasis, as estimated by the World Health Organization 13 An improved colorimetric PCR-based method for detection and differentiation of Entamoeba histolytica and Entamoeba dispar in feces.

Evaluation of a new bicolored latex agglutination test for immunological diagnosis of hepatic amoebiasis.

A newly revised classification of the protozoa. Virulence of Entamoeba histolytica trophozoites. Cutaneous amebiasis in children. Cloning and characterization of the Entamoeba histolytica pyruvate: Unfortunately, chronic nondysenteric intestinal amebiasis, which is characterized by intermittent diarrhea, flatulence, presence of seropositivity, and amebae in the stool, can resemble ulcerative colitis, resulting in misdiagnosis and treatment with corticosteroids ELISA is among the most popular methods used in diagnostic laboratories throughout the world.


Laboratory Diagnosis of Amebiasis

Antibody titers do uati appear to correlate with the severity of amebiasis or with the response to therapy. Multiplex polymerase chain reaction amplification and differentiation of Entamoeba histolytica and Entamoeba dispar DNA from stool samples. The gene organization of E. No cases have been documented where intestinal disease and colitis were caused by E.

Amebiasis infections are endemic in most temperate and tropical climates in the developing world.

The cytoplasm frequently contains many red blood cells RBCs that have been ingested. They increased to The essential role of amebic lectin in adhesin and cytolysis was first implied in The definitive diagnosis of ALA is confirmed by positive serological tests for antibodies to E. The presence of IgG antibodies in a single sample of serum does not indicate whether the infection was acquired before or during travel to an area of endemic infection Zymodemes expressing possible genetic exchange in Entamoeba histolytica.

The cyst stage of E. Also, it was found by IHA that the average antibody concentration began to decrease in the sixth month Interestingly, most individuals infected with E. However in some cases E. Antigen Detection Antigen-based ELISA have several significant advantages over other methods currently used for diagnosis of amebiasis: Differentiation of Entamoeba histolytica and Entamoeba dispar from German travelers and residents of endemic regions.

Due to the potential pitfalls of relying solely on a low-specificity serological test, a discriminatory method to allow such distinctions has been reported by Jackson et al.


Nuclear with irregular cluster of peripheral chromatin; large, irregular, eccentric karyosome. ALA occurs more commonly in adults than in children. Currently, there are many molecular tools available to allow the differentiation E. Experimental production of new zymodemes of Entamoeba histolytica supports the hypothesis of genetic exchange.

This classical feature has long been considered the definitive diagnostic criterion for E.

Prevalence of intestinal parasite infections with special reference to Entamoeba histolytica on the island of Bioko Equatorial Guinea. Serologic testing for amoebiasis. Clinical manifestations and diagnosis, p.

Autochthonous amoebiasis in institutionalized mentally-retarded patients: A single stool examination has a low sensitivity of detecting the parasite Diagnostic medical parasitology, 3rd ed. Cytopathogenic mechanisms of Entamoeba histolytica. 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 ameblasis.

An algorithm for the diagnostic approach to intestinal amebiasis is shown in Htai. Comparison of use of enzyme-linked immunosorbent assay-based kits and PCR amplification of rRNA genes for simultaneous detection of Entamoeba histolytica and E.

Molecular Biology-Based Diagnostic Tests and PCR To circumvent the problems of microscopic or culture-based diagnosis and take advantage of the sensitivity, specificity, and simplicity of newer techniques, molecular biology-based technology has become commonly used.
