Abstract Recent genetic population studies on Toxoplasma gondii in Brazil have shown large genetic variability. The objective of the present study was to isolate and genotypically characterize T. gondii from free-ranging and captive wild mammals and birds in Pernambuco state, Brazil. Fragments of heart,...

Abstract The aim of this study was to identify possible infection of Toxoplasma gondii among cats in a shelter and a set of condominiums in the city of Rio de Janeiro, through changes to the cats' serological status between two different times in 2014 and 2015. One group was made up of captive cats at t...
Abstract Toxoplasma gondii presents a high prevalence worldwide, infecting several animals. Felines are considered the definitive hosts and among the intermediate hosts we highlight mammals and birds. The man can become infected by ingesting tissue cysts present in birds and mammals. Biological and molec...

Objetivou-se avaliar a ocorrência, sinais clínicos e fatores de risco associados a soropositividade para Toxoplasma gondii e Neospora caninum em ovinos. Foram utilizados 294 animais com histórico de distúrbios reprodutivos de 28 fazendas do estado de São Paulo, Brasil, diagnosticados através da imu...
Abstract The aim of this study was to determine the occurrence of infections due to Toxoplasma gondii and Neospora caninum and corresponding risk factors among dogs attended at veterinary clinics in the city of João Pessoa, Paraíba, northeastern Brazil. Blood samples were collected from 384 dogs that w...

Descreve-se um caso de toxoplasmose congênita com microcefalia, ocorrido durante a epidemia de Zika vírus no Brasil e somente diagnosticado como toxoplasmose aos sete meses de idade. Este caso ilustra a pertinência e urgência para a implementação de políticas públicas específicas para prevençã...
Abstract INTRODUCTION: Knowledge of the epidemiological profile and risk factors for Toxoplasma gondii infection among postpartum women is a relevant issue, because this protozoan can be vertically transmitted to the developing fetus, which can cause severe and debilitating disease. The aim of this stu...
