[Differences in surface antigens of three diphyllobothriidae species, detected by serologic methods]

Immunochemical studies of somatic and surface extracts from D. dendriticum, D. ditremum and D. latum tape-worms demonstrated low specificity of somatic antigens of all three species and serological specificity of D. latum. D. dendriticum and D. ditremum, though serologically close, contained specific components demanding more precise extraction methods.
