Abstract This study focused on the detection of anti-Neospora caninum IgG antibodies in cows in the dairy farming region of the state of Piauí, Brazil. To this end, serum samples were collected from 255 dairy cows on 17 farms located in the dairy farming region of the municipality of Parnaíba, Piauí,...
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 Neosporosis is one of the major parasitic diseases that causes reproductive problems, making it a limitation for optimal efficiency in livestock. The aim of the present study was to conduct a seroepidemiological survey for bubaline neosporosis and to analyse associated factors associated with N...

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 Neosporosis is caused by an obligate intracellular protozoan, Neospora caninum . It is considered one of the most widespread and frequent causes of abortion in cattle worldwide. To evaluate the prevalence of anti-N. caninum antibodies and associated risk factors, serum samples were collected fr...

Abstract INTRODUCTION: We evaluated clinical and epidemiological characteristics of Trypanosoma cruzi infection in Sergipe. METHODS: In this cross-sectional study, we collected serum samples to identify serological markers of Chagas disease. A questionnaire was used, and electrocardiogram, echocardiogr...

Abstract INTRODUCTION: Serological cross-reactivity between leishmaniasis and Chagas disease, especially at low titers, leads to difficulties of the seroepidemiological interpretation. METHODS: We have studied the ability of urea as a chaotrope to select high-avidity antibodies in IgG ELISA, thus red...

Abstract INTRODUCTION: Herein, we assessed the seroprevalence and spatial distribution of Leishmania infantum in dogs in Garanhuns, Northeastern Brazil. METHODS: Sera samples (n = 242) were analyzed using an enzyme-linked immunosorbent assay (ELISA). The spatial distribution of dogs seropositive for ...

Abstract INTRODUCTION: The transmission of Chagas disease (CD) through blood transfusion, organ transplantation, and oral transmission has gained greater visibility as a result of intensified vector control activities in endemic regions and to control CD in non-endemic regions. In Brazil, Ceará is one...
Abstract This report describes the first autochthonous case of canine visceral leishmaniasis in Rondônia, northern Brazil. A canine resident of the municipality of Cacoal, with clinical signs and symptoms of visceral leishmaniasis, was treated by a veterinarian. Samples were analyzed by a reference labo...
