| Abstract: | The problem of the relationship between surface B antigen and schistosomiasis or other parasitic infections which are transmitted though the skin is not still resolved. Serum samples from 54 Somalian patients infected by Schistosoma haematobium were tested for the presence of the surface B antigen (HBsAg) and the e-antigen (HBeAg). The HbsAg was found in 14.8 per cent of these patients, while among controls (47 cases) the frequency was of 34.0 p]er cent; no e-antigen was found among the patients and controls, the prevalence of anti-HBs antibodies was of 57.4 per cent among the patients with urinary schistosomiasis and of 44.6 per cent among the controls; a low rate of anti-e antibodies was found in the patients (7.4%) and in the controls (10.6%). These observation seem to indicate that the problem of an increased frequency of hepatitis B virus markers among patients with urinary schistosomiasis needs for further investigation. |
