Protein typing by disc electrophoresis of some species of trypanosomes with special emphasis to Trypanosoma cruzi.

Proteins extracted from culture forms of T. cruzi, T. cruzi-like strains, T. rangeli, T. conhorrini and T. dionisii were separated by disc electrophoresis. The electrophoretic protein patterns of all strains examined were highly reproducible. The results indicate that each of these strains have their own "fingerprints" and the trypanosoma species could be identified by some typical specific protein bands. However, it was not possible to distinguish between the human strains of T. cruzi and the T. cruzi-like strains isolated from other sources.
