Introduction: Liver abscesses are mainly caused by parasitic or bacterial infection and are an important cause of hospitalization in low-middle income countries (LMIC). Entamoeba histolytica (Eh) is a protozoan parasite that causes amoebiasis characterized by intestinal damage and amoebic liver development and is an important cause of hospitalization in low-middle income countries.The aims of this study w ere to determine the prevalence and the titer of IgG anti Eh in ALA (Amoebic Liver Abscess) patients' in Bangui according sex, age and other . J Parasit Dis. PCR analysis of stool specimens was used to confirm that most antigen-positive but culture-negative specimens were true-positive: PCR identified parasite DNA in 27 of 34 (79%) of the antigen-positive, culture-negative stool specimens.

Although detection of IgM antibodies specific for E. histolyticahas been reported, sensitivity is only about 64% in patients with current invasive disease. This can be accomplished using: In addition, E. histolytica trophozoites can also be identified in aspirates or biopsy samples obtained during colonoscopy or surgery. The nonpathogenic Entamoeba dispar, however, is morphologically identical to E. histolytica, and differentiation must be based on isoenzymatic or immunologic analysis. Moreover, very high antibody titre (above cut-off) by IHA, ELISA and IFAT is diagnostic in endemic areas. 2003, 16:713-29. Would you like email updates of new search results?
