The results have showed a significantly (p less than 0,001) higher frequency of HBsAg among the patients with ancylostomiasis (33,33%) and with urinary schistosomiasis (25,92%) than either the leprosy patients (9,67% in the L type and 6,89% in the T type) or the controls (11,11%); in the leprosy patients with schistosomiasis the frequency was 40,0%. The role of some penetrating skin parasites in the epidemiology of hepatitis B was discussed.</p>  a0033-4979
