13. Evaluation of a rapid enzyme immunoassay for diagnosis of hepatic amoebiasis.
We compared the capability of rapid enzyme immunoassay (EIA) to detect antiamoebic antibodies during hepatic amoebiasis with those of indirect hemagglutination and latex agglutination. EIA is simple to perform and rapid (20 min) and does not require any special equipment (optical reading is sufficient). EIA of 143 sera (including 43 from patients with proven

14. Serological diagnosis of amoebiasis by immunofluorescence
A positive serological diagnosis of amoebiasis could be made by immunofluorescence in 66 of 78 established cases, taking a serum titre of 16 or higher as diagnostic: at this level there were no false positives among 94 control sera. The test is simple and may be carried out on amoebic smears stored for several months in 2-octanol. The serological activity is

18. Cloning and expression of a putative alcohol dehydrogenase gene of Entamoeba histolytica and its application to immunological examination.
To clone and express the genes encoding major antigens of Entamoeba histolytica, we constructed a lambda gt11 cDNA library for E. histolytica HM1:IMSS and screened it with pooled sera from patients with amoebiasis. A 1,223-bp cDNA was cloned (clone 1223), and its nucleotide sequence was determined. The amino acid sequence predicted to be encoded by the open

22. In vitro and in vivo interaction between trophozoites of Entamoeba histolytica and gerbil lymphoid cells.
The in vitro and in vivo antiamoebic cytotoxic effects of peritoneal exudate cells and mesenteric lymph node lymphocytes of gerbils with cecal amoebiasis or those immunized with amoebic extract were investigated. A differential effect of the lymphoid cells against trophozoites of nonpathogenic and pathogenic strains of Entamoeba histolytica was observed. Non

23. Role of macrophages in host defense against hepatic amoebiasis in hamsters.
The role of macrophages in hepatic amoebiasis in hamsters has been investigated by means of antimacrophage serum prepared in rabbits. Animals treated with normal rabbit serum or antimacrophage serum, as well as untreated controls, were inoculated intrahepatically with 10(5) axenic trophozoites of Entamoeba histolytica. In hamsters treated with antimacrophage

24. Comparison of indirect fluorescent-antibody amoebic serology with counterimmunoelectrophoresis and indirect hemagglutination amoebic serologies.
Patients ranged from those with no prior diagnosis of or suspected exposure to Entamoeba histolytica to those with proven amoebic liver abscesses (extraintestinal disease). A comparison of serologies from patients with proven and suspected amoebiasis or possible past exposure revealed good correlation between the indirect fluorescent antibody (IFA) procedure
