The immunological responses in relation to egg extrusion rate and pathological changes in Schistosoma haematobium patients.

A total of 30 males with proven S. haematobium infection were subjected to egg count, serological estimation of serum levels of soluble egg antigens and its specific antibody "SEA IgG" and cystoscopic examination of lower urinary tract. Correlation between the pathological changes and number of living extruded eggs showed negative insignificant correlation. However, the relation between the pathological changes and anti-SEA IgG showed positive insignificant correlation.
