title: Delimitation of Trypanosoma cruzi zymodemes by numerical taxonomy.
abstract: Based on the absence or presence of 24 isoenzyme characters, Brazilian Trypanosoma cruzi stocks can be separated by methods of numerical taxonomy into three principal, distinct groups; these groups correspond to the three T. cruzi zymodemes previously reported from north Brazil. A distinction is drawn between taxonomy, which may be of zoological interest only, and identification of medically important groups according to one or a few distinguishing characters.
