A simple method was developed for the characterization of different strains of Trypanosoma cruzi. T. cruzi stocks isolated from vectors or by hemoculture from patients with Chagas disease could be grouped in subpopulations having similar patterns of restriction endonuclease products of kinetoplast DNA minicircles. We designate such subpopulations by the term “schizodemes.” Furthermore, it is shown that, from a given T. cruzi strain, clones with different biological properties can be isolated and identified by their restriction patterns.
