Abstract INTRODUCTION Medical students have an occupational risk for hepatitis B (HB). This study sought to determine anti-HBs and anti-HBc IgG levels in vaccinated students, check their seroconversion, and correlate this with vaccination. METHODS One hundred and forty-three students' blood samples a...

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...

Abstract INTRODUCTION We evaluated the anti-hepatitis E virus (HEV) antibody prevalence and HEV-RNA in archived serum samples of non-A-C hepatitis, or suspected cases of HEV infection from the Eastern Brazilian Amazon from 1993 to 2014. METHODS Serum samples (n = 318) were tested using ELISA and immu...

Abstract INTRODUCTION: Toxoplasmosis is an asymptomatic disease that can lead to systemic disease in the fetus of pregnant women with primary infection. This study aimed to determine the prevalence of toxoplasmosis, associated factors, and correlation between the serology of pregnant women and their pe...

Anthropogenic environmental changes arising from settlement and agriculture include deforestation and replacement of natural vegetation by crops providing opportunities for pathogen spillover from animals to humans. This study aimed to investigate the prevalence of rodent-borne virus infections in seven ...

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...
Abstract INTRODUCTION: The prevalence of Toxoplasma gondii infection varies markedly among different populations, especially depending on factors related to socioeconomic development and eating habits. Cássia dos Coqueiros is a small city in Brazil with rural characteristics and increased risk factors...

Abstract INTRODUCTION: In most Strongyloides stercoralis infected individuals, nematoidosis occurs asymptomatically, but in immunocompromised patients, it can cause hyperinfection. Serological techniques seem to be a good alternative for detecting this parasite. METHODS The frequency of seropositivit...
Abstract INTRODUCTION The prevalence, public health impact, and epidemiological characteristics of hepatitis E virus (HEV) are poorly understood in Brazil. METHODS Serum samples from 535 individuals from three rural Afro-descendant communities located in eastern Brazilian Amazon were collected in Oct...
