SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica in direct microscopic exam. The control group showed a titre of 1/40 or less with this organism. It was found that the finding at a titre 1/320 to E. Histolytica would be of clinical value for diagnosis of Amoebiasis among diarrheal patients. Also among 35 of patients (34.3 % ) the antibody titre were found to be 1/80 and 1/60 while may be related to them past infection, non invasive amoebic or cross reaction.
