Coinfecções por Leishmania infantum, Neospora caninum e Toxoplasma gondii em cães necropsiados da região central do Rio Grande do Sul, Brasil

O objetivo do presente trabalho foi determinar a presença de anticorpos para Leishmania infantum, Neospora caninum e Toxoplasma gondii, por meio da reação de imunofluorescência indireta (RIFI), em cães (n=78) provenientes da região central do Rio Grande do Sul, necropsiados no Hospital Veterinário...

An in silico pipeline to filter the Toxoplasma gondii proteome for proteins that could traffic to the host cell nucleus and influence host cell epigenetic regulation

Mem. Inst. Oswaldo Cruz; 113 (6), 2018
Toxoplasma gondii uses epigenetic mechanisms to regulate both endogenous and host cell gene expression. To identify genes with putative epigenetic functions, we developed an in silico pipeline to interrogate the T. gondii proteome of 8313 proteins. Step 1 employs PredictNLS and NucPred to identify genes ...

Fatal toxoplasmosis in a southern muriqui (Brachyteles arachnoides) from São Paulo state, Brazil: Pathological, immunohistochemical, and molecular characterization

We report the pathological, immunohistochemical, and molecular features of fatal acute systemic toxoplasmosis in an adult, female, free‐living southern muriqui (Brachyteles arachnoides) from São Paulo state, Brazil. PCR‐RFLP genotyping analysis identified the #21 genotype of Toxoplasma gondii. This ...

Resumen Introducción El diagnóstico de toxoplasmosis congénita (TC) en el recién nacido es muy importante porque debe recibir tratamiento siempre, sintomático o no, para evitar o aminorar las secuelas de la enfermedad. Objetivo Evaluación comparativa de los métodos disponibles en la institución...

Molecular diagnosis of symptomatic toxoplasmosis: a 9-year retrospective and prospective study in a referral laboratory in São Paulo, Brazil

Braz. j. infect. dis; 21 (6), 2017
ABSTRACT Symptomatic forms of toxoplasmosis are a serious public health problem and occur in around 10-20% of the infected people. Aiming to improve the molecular diagnosis of symptomatic toxoplasmosis in Brazilian patients, this study evaluated the performance of real time PCR testing two primer sets (B...

Prevalence of anti-Toxoplasma gondii antibodies in blood donors in Buenos Aires city, from 1967 to 2017

Medicina (B.Aires); 77 (6), 2017
Se estudió la prevalencia de anticuerpos anti Toxoplasma gondii a los dadores voluntarios de sangre que concurrieron durante el primer cuatrimestre de los años 1997, 2007 y 2017 al Servicio de Hemoterapia del Hospital Alemán de Buenos Aires y se compararon los resultados con el estudio efectuado en el...

Serosurvey of Leptospira spp. and Toxoplasma gondii in rats captured from two zoos in Southern Brazil

Abstract INTRODUCTION: Norway rats (Rattus norvegicus) are zoonotic reservoirs for Leptospira spp. and Toxoplasma gondii, and influence diseases in urban areas. METHODS: Free-ranging and laboratory-raised rats from two zoos in southern Brazil were tested for Leptospira spp. and T. gondii using micros...
