Trypanosoma cf. carassii: the combination of malic enzyme patterns supports the theory of diploidy in trypanosomes.
Electrophoretic analysis of Trypanosoma cf. carassii strains from cyprinid fish revealed three basic types of enzyme patterns of malic enzyme (ME) in forms from culture. Two enzyme patterns were one-banded and differed only slightly in electrophoretic mobility. The third pattern consisted of three bands, the two marginals corresponding to respective bands of one-banded patterns and the third located in the middle. ME is thought to be dimeric in trypanosomes and therefore the triple-banded pattern may be regarded as the hybrid from combination of the former two. This fact supports the concept of diploidy in fish trypanosomes.
