Isozymic studies and epidemiological data of Trypanosoma cruzi from Arequipa (Perú), Pacific side

Abstract

Summary. The authors present some epidemiological data (infestation rates for houses and triatomine vectors) concerning Chagas' disease in Arequipa region (Peru). lsoenzymic analysis of 39 Trypanosoma cruzi stocks from this region shows a predominance of stocks related to Miles' zymodeme 1 and to isoenzymic strain 1e. Four stocks were mixtures of isoenzymic strains 1e and 2. Low isoenzymic variability of the stocks from this region can be explained by a founder effect.
