A homogenate prepared from dried T. spiralis larvae was fractionated by means of paper electrophoresis on a starch block in borate buffer at pH of 8.6. The immunologie activity of fractions was examined by diffusion and gel inmmunoelectrophoresis using complement fixation, ring precipitation tests, as well as determinining protein, saccharides and enzyme levels. It was found that the fractions obtained possess the properties of protein antigens. Among 26 fractions, those from 9 to 14 proved to be serologically active. The antigens were found to contain acide phosphatase and hvaluronidases.
