title: On the methods of obtaining diphyllobothriid surface antigens.
abstract: A new method of obtaining the diphyllobothriid surface antigens has been developed. It allows to obtain antigens with the increased content of the surface components of worm strobila. It was found that the antigens from extracts I are relatively more active than the antigens from extracts II and III.
