<p><b>A</b>. Chromosomal bands of Choachí and SC-58 isolates were separated via PFGE and stained with ethidium bromide. The bands were numbered using Arabic numerals, starting from the smallest band. <b>B</b>. Chromosomal bands from <i>T. rangeli</i> (Choachí and SC-58 strains) and <i>T. cruzi</i> (clone CL Brener) were fractioned using a protocol optimized to separate small DNA molecules, revealing the absence of minichromosomes. The brackets represent the size range of <i>T. brucei</i> minichromosomes (30 and 150 kbp).</p
