Background Chagas disease prevention critically depends on keeping houses free of triatomine vectors. Insecticide spraying is very effective, but re-infestation treated dwellings commonplace. Early detection-elimination foci key to long-term control; however, all available vector-detection methods have low sensitivity. Chemically-baited traps are widely used in vector and pest control-surveillance systems; here, we test this approach for Triatoma spp. detection under field conditions the...
SUMMARY Active Trypanosoma cruzi transmission persists in the Gran Chaco region, which is considered hyperendemic for Chagas disease. Understanding domestic and sylvatic cycles therefore relationship between vectors mammalian hosts crucial to designing implementing improved effective control strategies. Here we describe species of triatomine mammal reservoirs T. , different localities Paraguayan Bolivian Chaco. We identify genotypes discrete typing units (DTUs) provide a map their...
Triatoma sordida is widely distributed throughout the Chaco and Eastern Region of Paraguay. It associated to palm trees artificial ecotopes located in peridomestic environments. The aim this work was determine genetic morphometric variability feeding behavior among population T. captured domicile peridomicile areas Feeding contents levels variation were determined 124 from populations San Pedro Paraguarí departments Boquerón Presidente Hayes Western region using Double Diffusion Gel, Random...
Twenty one Trypanosoma cruzi stocks from humans, domiciliary triatomines and sylvatic animal of different areas Paraguay were subjected to isoenzyme analysis. Thirteen enzyme systems (15 loci in total) studied. MN cl2 (clonets 39) SO34 cl4 20) used as references. Relationships between depicted by an UPGMA dendrogram constructed using the Jaccard´s distances matrix. Among Paraguayan 14 zymodemes identified (Par1 Par14), Par 5 being most frequent. Polymorphism rate clonal diversity 0.73 0.93,...
To verify the occurrence of natural Trypanosoma cruzi infection in non-human primates from a rural endemic area east region Paraguay, xenodiagnosis was performed 35 animals belonging to two species. For genotyping and T. discrete typing unit (DTU) assignment, combination four markers used, including amplification products small (18S) large (24Sα) subunits ribosomal ribonucleic acid gene, intergenic mini-exon gene heat shock protein 60 Eco-RV polymerase chain reaction-restriction fragment...
Introducción. Trypanosoma cruzi, agente causal de la enfermedad Chagas, exhibe una sustancial heterogeneidad fenotípica y genotípica que puede influir en las variaciones epidemiológicas clínicas enfermedad, así como sensibilidad a los fármacos utilizados el tratamiento.Objetivo. Evaluar in vitro al benznidazol, nifurtimox posaconazol 40 cepas clonadas T. cruzi Paraguay, con distintos genotipos, huéspedes localidades origen.Materiales métodos. En su estado epimastigote, parásitos se incubaron...
La enfermedad de Chagas es hasta hoy día endémica en el Chaco paraguayo, perjudicando principalmente a las poblaciones rurales o menores recursos económicos, representando así comunidades indígenas algunas más vulnerables. El objetivo este trabajo fue determinar la presencia triatominos vectores Trypanosoma cruzi Ayoreo Totobiegosode Chaidi y Aocojadi del Alto Paraguay. Se evaluaron características viviendas su relación con permanencia vectores. búsqueda se realizó intradomicilio...
