Abstract INTRODUCTION Solid-organ transplant recipients are at risk of hepatitis E virus (HEV) infection. We analyzed the seroprevalence/risk factors of HEV in Croatian liver transplant recipients. METHODS Two hundred forty-two serum samples were tested for HEV immunoglobuline IgG/IgM and HEV RNA. So...

Anti-α-Gal responses may exert a protective effect in falciparum malaria. However, the biological role of such antibodies is still unknown during Plasmodium vivax infections. We investigated IgG and IgM responses to α-Gal in individuals with vivax malaria. Anti-α-Gal IgG and IgM levels wer...
Los estudios de toxoplasmosis en Bolivia han sido efectuados en gestantes que acuden a sus controles prenatales y escasos los referidos a factores de riesgo para la enfermedad. De esa manera el objetivo de la presente investigación fue establecer los factores de riesgo y la seroprevalencia para toxoplas...
Objetivos: descrever os resultados da dosagem de IgM em pacientes com confirmação diagnóstica de infecção congênita pelo zika vírus, avaliando a relação com período no qual a infecção materna ocorreu, a janela diagnóstica e as alterações clínicas nos casos estudados. Metodologia: foram av...
Abstract INTRODUCTION: The prevalence of Toxoplasma gondii infection varies markedly among different populations, especially depending on factors related to socioeconomic development and eating habits.

Abstract INTRODUCTION West Nile virus (WNV) immunoglobulin M (IgM) antibodies have been shown to persist for up to 500 days in certain patients. To evaluate the usefulness of immunoglobulin G (IgG) avidity assessment in the diagnosis of WNV infection, we analyzed 54 WNV IgM- and/or IgG-positive serum s...
