Este estudio ha tenido como finalidad actualizar los datos de parasitosis intestinal, estudiando 227 muestras de heces de niños de 1 a 12 años de comunidades rurales y urbanas. Se han empleado cuatro métodos: directo, de flotación o Willis, de concentración o MGL y Harada-Mori, éstos dos últimos d...
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...
The polymerase chain reaction (PCR) was usedto evaluate the course of treatment of an acutely infected patient with Trypanosoma cruzi. The reactions were performed using a primer pair (TCZ1 and TCZ2) which prime the amplification of a highly repetive 195-bp T. cruzi genomic DNA. Treatment with benzonidaz...
Anatomopathological studies were performed in 15 placentas of pregnant women who were seropositive for Chagas' disease. Nests of Trypanosoma cruzi amastigote s were found in the placenta and umbilical cord of three of them (20 percent). The parasitism was extensive in two of the cases, where the nests we...
The rhabdoid tumor of kindey (RTK) is a neoplasia with well defined clinical and pathological characteristics. Itis is very important to distinguish it form the Wilms'tumor, because RTK is a very aggressive and has poor prognosis. The first case of a RTK diagnsed in Paraguay is presented.The diagnosis wa...
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 ...
