Abstract
Summary Specific and distinct protein profiles were demonstrated by isoelectric focusing performed on soluble whole-body proteins of four Diphyllobothrium species. The protein patterns differed in number, position and relative density of the fractions separated. Altogether 31–36 protein bands per species were separated by isoelectric focusing in thin-layer polyacrylamide gels. The results show that sensitive chemotaxonomic methods can be used to help characterize and delimit species in the troublesome Diphyllobothrium group.
