Abstract：
Our research work group has been interested in the study of the ribosomal RNA and 5S gene systems from Trypanosoma cruzi. Our contributions span from the general description of a multifragmented molecular system, to the sequence analysis of some ribosomal RNA coding regions. From the latter, we have constructed phylogenetic trees of the Trypanosomatidae family, and our data indicate that the molecular inferences do not sustain the traditional classification of these species. Our published findings are here reviewed along with recent unpublished observations of ribosomal RNA and 5S gene structures.
