ABSTRACT
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.

Children living in institutions as orphanages are more exposed to intestinal parasitism, since crowding and behavioral pattern contribute greatly to the spread of parasitic infection. The present study was conducted on 100 children living in Ain-Shams and El-Mowassa orphanages, Cairo. Twenty children living under appropriate health conditions were studied as controls. Ages of both groups ranged from 6-12 years. The results of this study revealed that 69/100 (69%) orphanage children were positive for parasitic infection, while 8/20 (40%) control subjects were positive for parasitic infection; the difference was statistically significant. Enterobius vermicularis was the commonest parasite among both groups. Other parasitic infections detected were; Giardia lamblia, Entamoeba histolytica, Hymenolepis nana and Entamoeba coli with a prevalence of 10%, 9%, 2% and 9% respectively in the study group compared to 15%, 10%, 0% and 5% in the control group; the differences were statistically not significant. Cryptosporidium oocysts were not detected in both groups.

Helminthotoxic effect of eosinophils on schistosomula of S. mansoni was studied in thirty patients with peripheral eosinophilia of different causes. Ten cases presented with parasitic infections and twenty cases were parasite free. Twenty healthy persons with normal blood picture were tested as a control group. The adherence assay test of eosinophils and the assay of cell mediated damage of eosinophils to schistosomula were used. The percentages of the adherence and the toxic effect of eosinophils were the same for each group. They were 85.1% in the parasitic group, 85.45% in the non parasitic with other causes group and 13.9% in the control group. The difference was statistically highly significant (P less than 0.001).

Electron microscopic study of the flagellar apparatus of promastigote and amastigote forms of Leishmania revealed major differences. Promastigotes were characterized by possessing a paraxial rod with a well developed lattice-like complex alongside the emerging axoneme enclosed within the flagellar sheath. The latter was anchored to the protozoan plasma membrane by focal or spot-like macular desmosomes at the emergence site. With cytodifferentiation to amastigotes there was a notable reduction in the axonemal size and its microtubular elements, absence of paraxial rod and a remarkable binding of the endocellular flagellum to its pocket through dense zonular desmosomal adhesions.

Two leishmanial stocks isolated in Egypt, one from a dog and the other from Rattus norvegicus, were typed according to their excreted factor (EF) serotype and the electrophoretic mobility of their glucose phosphate isomerase. The canine isolate was indistinguishable from L. donovani (= L. infantum ) strains. The rat isolate appeared to be different from L. donovani, L. tropica and L. major.
