Identification of helminth species by means of disc electrophoresis.

Soluble proteins of 25 helminth species of the classes Trematoda, Cestoidea and Nematoda, were separated by disc electrophoresis using polyacrylamide gel columns. Differences between the species were investigated on the basis of Rm values of the bands. Protein spectra were complemented by the detection of lipoproteins and glycoproteins and by identification of LDH, SHD, peroxidase, esterase and alkaline phosphatase. On the basis of comparison of protein spectra of parasitic worms belonging to three taxonomic classes it was found by means of numerical taxonomy that individual classes are characterized by a certain number of proteins of the same migration properties.
