Course of serological tests in treated subjects with chronic Trypanosoma cruzi infection: A systematic review and meta-analysis of individual participant data.

Objective: To determine the course of serological tests in subjects with chronic Trypanosoma cruzi infection treated with anti-trypanosomal drugs.

Methods: A systematic review and meta-analysis was conducted using individual participant data. Survival analysis and the Cox proportional hazards regression model with random effects to adjust for covariates were applied.

Finding of leishmanicidal activity of 14-hydroxylunularin in mice experimentally infected with Leishmania infantum.

In this study, we report the in vivo efficacy of 14-hydroxylunularin evaluated in BALB/c mice experimentally infected with promastigotes of Leishmania infantum (syn L. chagasi), the major causative agent of visceral leishmaniasis in Latin America. Seven days post-infection, treatment with 14-hydroxylunularin started and it was administered by oral and subcutaneous routes in doses of 10 and 25 mg/kg of weight for ten days using Glucantime® as reference drug.

Genetic and Morphometric Variability of Triatoma sordida (Hemiptera: Reduviidae) from the Eastern and Western Regions of Paraguay.

Triatoma sordida is widely distributed throughout the Chaco and the Eastern Region of Paraguay. It is associated to palm trees and artificial ecotopes located in peridomestic environments. The aim of this work was to determine genetic and morphometric variability and feeding behavior among population of T.
