Peer Review Process

Manuscripts submitted to Memorias del Instituto de Investigaciones en Ciencias de la Salud undergo a double-blind peer review process, in which the identities of both authors and reviewers remain anonymous throughout the evaluation. Each manuscript is assessed by a minimum of two external reviewers with expertise in the relevant subject area, who are given a period of 30 days to submit their evaluation. Reviewers assess the originality, methodological rigor, scientific relevance, and clarity of presentation of each work. Based on the reviewers' reports, the Editorial Committee decides whether to accept, request revisions, or reject the manuscript, and communicates the decision to the authors as promptly as possible. This process ensures impartiality, transparency, and the scientific quality of published articles.

Abstract

La transmisión enzoótica del Trypanosoma cruzi en Paraguay aún no ha sido bien determinada. Por lo tanto, todavía se desconocen varios aspectos de la dinámica de transmisión de este parásito en el medio selvático, como ser especies de reservorios naturalmente infectados, cepas circulantes y el grado de interacción con el ciclo doméstico. Con los estudios realizados hasta la fecha, se han identificado cinco especies como reservorios naturales del T. cruzi: Didelphis azarae, Monodelphis domestica, Dasypus novemcinctus, Euphractus sexcinctus y Chaetophractus spp. en el ambiente silvestre de zonas endémicas para la enfermedad de Chagas (Chaco y San Pedro). Entre éstas se destaca la especie Dasypus novemcinctus, en la cual se ha observado una alta prevalencia de infección de alrededor del 50%. En el ambiente doméstico, se han reportado perros infectados con este parásito en mayor proporción y en menor grado gatos, reses y cerdos.
