title: [Multiple forms of NAD-dependent malate dehydrogenase in 3 species of trematodes of the genus Notocotylus (Trematoda: Notocotylidae)].
abstract: NAD dependent malate dehydrogenases of three trematode species, Notocotylus attenuatus, N. ephemera and N. imbricatus, have been investigated by electrophoresis. Seven different zones with 15 isoenzymes in N. attenuatus, 16 isoenzymes in N. ephemera and 11 isoenzymes in N. imbricatus have been found in MDH spectra. Isoenzymes of MDH are controlled by seven polymorphic loci. The activity of isoenzymes of three slowly migrating zones is 10 and more times higher than that of fast zones (4-7). The genotypes of adults in one strain are genetically identical, independent ot the development in different definitive hosts. The spectra of MDH of the investigated Notocotylus species are different in slowly migrating isoenzymes (1-3 zones).
