RESUMO
A total of 70 bilharzial mansonian patients (Group I: 20 early intestinal mansonian patients, Group II: 20 hepatosplenic mansonian patients without ascites, Group III: 30 hepatosplenic mansonian patients with ascites) and 30 normal controls were studied. Using the circumoval percipitin test (COPT), there was a statistically significant difference between sensitivities in Group I and Group III with higher sensitivity for Group I. Using either the indirect haemagglutination test (IHA) or the indirect fluorescent antibody test (IFAT), there was no statistically significant difference between the sensitivities in the different bilharzial groups. No statistically significant difference was found between the 3 tests in Group I, II respectively. A statistically significant difference was found between the sensitivities of COPT and IHA in Group III. A highly significant difference was found between the sensitivities of COPT and IFAT in Group III also. No statistically significant difference was found between the sensitivities of IFAT and IHA in Group III. There was no statistically significant difference between the percentages of positivity of hepatitis B surface antigen (HBSAg) in the different bilharzial groups while each of the 3 groups showed highly statistically significant difference with the control group. No statistically significant difference was found between the positivities of HBSAg and the different titers of either IHA of IFAT in each group.

Stool specimens of 100 cases attending the outpatient clinic of Cairo Medical Center Hospital suffering from gastro-intestinal disturbances were examined for intestinal parasites by direct smear, trichrome stained smear and formol ethyl acetate concentration methods. Although formol ethyl acetate concentration method gave the best results (45%), followed by trichrome stain (37%) then direct smear (32%) yet, for a reliable diagnosis a combination of several techniques is required.
