Abstract. 132 Trypanosoma cruzi stocks were collected in southern Bolivia (99 stocks in Tupiza, 33 in Tarija), and were characterized using five enzymes (six loci). From these 132 stocks, a sample of 21 was studied using ...

Summary. lmmunoelectrophoresis (lEP) and a double diffusion microtest (MD) were evaluated for ¡mmunological diagnosis of Chagas' d¡sease, using 527 sera from Bolivian patients. The specificity of, the tests was given ...

Abstract. By changing clcctrophoretic conditions additional genetic variability was observed in both previously and newly analysed enzymatic systemes in Trypanosoma cruzi . Inferences the quaternary structure of enzymes ...

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 ...

Summary. Genetic interpretation of. T. cruzi zymograms has led to various hypotheses which are reviewed.

Trypanosoma cruzi, the etiological agent of Chagas' disease, is a very heterogeneous population of parasites circulating among man, vectors and wild and domestic reservoirs. Until now, few data have been ...

Abstract. We have collected in Bolivia 212 stocks of Trypanosoma cruzi from domestic transmission cycles and have assayed for nine enzyme systems (11 gene loci). Only a few different isozyme profiles exist, without ...
