1. Mulheres que já tiveram toxoplasmose, apresentam risco de transmissão ao feto na gestação?
O tempo de parasitemia da toxoplasmose é curto. Assim, mulheres imunocompetentes que engravidarem 3 meses após terem tido toxoplasmose, tem um risco quase nulo de transmissão para o feto
. Alguns serviços ainda recomendam que mulheres com diagnóstico de toxoplasmose aguardem 6 meses após a infecção para engravidar
. Cabe considerar ain

2. Chemical Prospection of Qualea grandiflora Mart. Fruit and Stem Extracts and Their in vitro and in vivo Antiplasmodial Activity
Qualea grandiflora Mart. (“pau-terra”) is a medicinal plant symbolic from Cerrado biome. Qualea species reportedly have antiparasitic properties, but their active compounds have yet to be identified. In this study, we investigated the antiplasmodial activity of Q. grandiflora fruit and stem extracts against Plasmodium falciparum. The polar extracts of bo

3. In vitro and in vivo antimalarial activity of the volatile oil of Cyperus articulatus (Cyperaceae)
RESUMO A malária é uma doença de distribuição tropical, sendo endêmica em mais de 90 países, responsável por cerca de 212 milhões de casos reportados ao redor do mundo em 2016. As estratégias de erradicação dessa doença são ineficazes até o presente, sem medidas de prevenção específica, como vacinas. Atualmente, o arsenal terapêutico exist

4. Comparison of conventional and molecular techniques for Trypanosoma vivax diagnosis in experimentally infected cattle
Resumo Infecções por Trypanosoma vivax têm ocorrido com frequência crescente em animais de produção, principalmente pela aquisição de animais com infecções subclínicas e sem aparente parasitemia, o que dificulta o diagnóstico. O objetivo do presente estudo foi avaliar várias técnicas empregadas para o diagnóstico de T. vivax, a fim de verifica

5. Effect of acetylsalicylic acid on total myenteric neurons in mice experimentally infected with Trypanosoma cruzi
Abstract: We investigated the effects of acetylsalicylic acid (ASA) on the total myenteric neuronal population in the descending colon in Trypanosoma cruzi-infected mice. Thirty-five male Swiss mice, 60 days old, were divided into a control group (C group), control group treated with ASA (CA group), infected group (I group), and infected group treated with A

6. Fatal evolution of acute Chagas disease in a child from Northern Brazil: factors that determine poor prognosis
ABSTRACT Trypanosoma cruzi is the causative agent of Chagas disease. Nowadays, the transmission in Brazil occurs mainly by oral ingestion of contaminated food that has been associated with more severe clinical manifestations. We report a case of Acute Chagas disease caused by oral transmission in a child from Northern Brazil. In the hospital admission, physi

7. Impact of autologous whole blood administration upon experimental mouse models of acute Trypanosoma cruzi infection
Abstract Background: Autologous whole blood (AWB) administration is described as alternative/complementary medical practice widely employed in medical and veterinary therapy against infections, chronic pathologies and neoplasias. Our aim is to investigate in vivo biological effect of AWB using healthy murine models under the course of Trypanosoma cruzi acut

8. Antioxidant effect of Morus nigra on Chagas disease progression
ABSTRACT Considering the widespread popular use of Morus nigra and the amount of scientific information on its antioxidant and anti-inflammatory activity, the effectiveness of this phytotherapeutic compound in the parasitemia progression during the acute phase of Chagas disease and its role in the development of the inflammatory process as well as its effect

9. Selective malaria antibody screening among eligible blood donors in Jiangsu, China
ABSTRACT The risk of transfusion-transmitted malaria is a major concern in many countries. This study investigated the prevalence of malaria antibodies and parasitemia in eligible blood donors in Jiangsu, in Eastern China. Malaria antibodies were detected in 2.13% of the 704 plasma samples studied. We found that the prevalence of malaria antibodies was not s

10. Detecção de Toxoplasma gondii em tamanduá-bandeira de vida livre
RESUMO: A toxoplasmose é causada pelo Toxoplasma gondii, um protozoário intracelular obrigatório, que estabelece infecções agudas e crônicas em aves e mamíferos, incluindo humanos. Esta nota relata, pela primeira vez, a detecção e o sequenciamento do DNA de T. gondii em sangue periférico de um filhote de tamanduá-bandeira (Myrmecophaga tridactyla

11. Influence of environmental enrichment on the behavior and physiology of mice infected by Trypanosoma cruzi
Abstract INTRODUCTION: Enriched environments normally increase behavioral repertoires and diminish the expression of abnormal behaviors and stress-related physiological problems in animals. Although it has been shown that experimental animals infected with microorganisms can modify their behaviors and physiology, few studies have evaluated how environmenta

12. Evaluation of antioxidant therapy in experimental Chagas disease
Abstract INTRODUCTION: Stimulation of inflammatory mediators such as cytokines and chemokines may cause oxidative stress in Chagas disease. In this study, we evaluated the merit of vitamins C and E as antioxidant therapy to minimize the oxidative stress-induced damage in an experimental model of Chagas disease. METHODS: Ninety-six Swiss mice were infecte
