Comparison between parasitological and serological techniques in assessment of schistosomiasis prevalence

The prevalence of schistosomiasis serologically based on detection of anti-soluble egg antigen [SEA] -IgM and/or IgG by ELISA technique was 68% of 380 cases, and 52.7% of 148 cases by stool examination. The serological technique seems to be more sensitive and able to detect early infection as well as detection of ectopic infection

Correlation between circulating schistosomal antigen, schistosomal complement C3 and intensity of infection

53.7% of the already parasitologically proved schistosomiasis cases showed circulating schistosomal antigen [C.S.A.] in their sera with significantly higher levels than the controls, with no correlation between the level of C.S.A. and the foecal egg count. Significant higher levels of schistosomal complement C3 were found in schistosomiasis patients as compared to the control group, with no significant difference in the mean level of C3 between patients with positive and negative C.S.A

Four methods in diagnosing protozoal parasites in stool

Stool examination by 4 different methods showed that zine sulphate floatation technique was more or less the best

Schistosomiasis and transient nephritis in children

Transient nephritis, manifested by albuminuria may be caused by the deposition of the circulating schistosomal antigen in the kidney glomeruli

Urinary infection in simple schistosomiasis in children

Urinary bilharziasis acts as a predisposing factor to urinary tract infection. The incidence of infection was higher in patients with chronic infection. Females showed higher incidence of urinary tract infection than males. The most predominant organism isolated was E. coli. Nalidixic acid was found to be the most effective drug in urinary tract infection in bilharziasis
