Blood trnasfusion is the second most importnatmechanism of transmission of Chagas'disease in both endemic and non-endemic areas. In Latin America, more than 20,000 cases of transmission of the disease, trough blood transfusion, may be occurring. Gentian Violet is currently the only available trypanicidal...
Trypanosoma cruzi amastigotes derived from fibroblast cultures and from cell- free liquid mediun were comparatively evaluated as solid-phase of Elisa for Chagas' disease. Amastigotes were obtained from the high- and low-virulent clones of the Talahuen strain and fron the G-1 strain. They were sonicated a...
Chromosome observations of triatomine bugs known as medically important vectors of American tripanosomiasis (Chagas' disease) were attempted. We demonstrated by the C-band technique that brazilian strain of Triatoma infestans includes at least three cytotypes in terms of constitutive heterochromatin poly...
Strains of Trypanosoma cruzi isolate in Paraguay from patients and vectors were examiqned by restriction endonuclease analysis of K-DNA using Eco RI, Hae III, Hinf I, Msp I. Four different types of schizodeme profiles were identified in 11 isolates. The firs group has much simpler profiles than ther grou...
The microfilaricidal effect if invermectin was studied on Cebus apella infected with dipetalonema gracile in Paraguay. Nine monkeys were treated with ivermectin at the dosage of 200 ug/kg boby wieght by single subcutaneous injection. The significant reduction in microfilarial count after treatament with ...
A graphic key for the identification of male and female phlebotomines caught in Paraguay was prepared. The objective of this work is to facillitate the identification of these insects by health workers interested in leihmaniasis control...
