1. Diagnosis of Schistosoma mansoni infections: what are the choices in Brazilian low-endemic areas?
The population of Brazil is currently characterised by many individuals harbouring low-intensity Schistosoma mansoni infections. The Kato-Katz technique is the diagnostic method recommended by the World Health Organization (WHO) to assess these infections, but this method is not sensitive enough in the context of low egg excretion. In this regard, potential

3. Prevalence of schistosomiasis mansoni in indigenous Maxakali villages, Minas Gerais, Brazil
ABSTRACT Intestinal parasitic infections are a common health problem among Amerindian populations and schistosomiasis represents one of the most prevalent diseases in Maxakali people. The Kato-Katz is the diagnostic method recommended by WHO for epidemiological studies; however, one of the technique’s limitations is the failure to detect parasites in indiv

4. Detection of schistosomiasis in an area directly affected by the São Francisco River large-scale water transposition project in the Northeast of Brazil
Abstract INTRODUCTION: The development of the São Francisco River Integration Project [Projeto de Integração do Rio São Francisco (PISF)] in the State of Ceará, Brazil, has resulted in environmental and socioeconomic changes with potential risks to public health. We aimed to determine the presence of Schistosoma mansoni infections in schoolchildren (a

5. Performance of POC-CCA® in diagnosis of schistosomiasis mansoni in individuals with low parasite burden
Abstract: INTRODUCTION: Schistosomiasis, caused by Schistosoma mansoni, is a public health concern in Brazil. However, the most popular diagnostic method, the Kato-Katz technique, exhibits low sensitivity in low-endemicity areas. We aimed to compare the performance of an immunological assay, the point-of-care circulating cathodic antigen (POC-CCA®) test,

6. Clinical and serological outcomes with different surgical approaches for human hepatic hydatidosis
ABSTRACTINTRODUCTION:Hydatidosis is the result of infection with the larval stages of some species of the genus Echinococcus. Treatment approaches for hydatid cysts include the use of albendazole, surgery, and/or medico-surgical procedures. The choice of the therapeutic surgical approach depends on the cyst number and localization, surgeon expertise, and pre

7. A conventional polymerase chain reaction-based method for the diagnosis of human schistosomiasis in stool samples from individuals in a low-endemicity area
The aim of this study was to evaluate the efficacy of a polymerase chain reaction (PCR)-based method to detect Schistosoma mansoni DNA in stool samples from individuals living in a low-endemicity area in Brazil. Of the 125 initial stool samples, 80 were ELISA reactive and eggs were identified in 19 of the samples by parasitological examination. For the PCR e

8. The combination of three faecal parasitological methods to improve the diagnosis of schistosomiasis mansoni in a low endemic setting in the state of Ceará, Brazil
Laboratory diagnosis of intestinal schistosomiasis mansoni can be accomplished through various methods of stool examination to detect parasites, ranging from the most classic tests (Kato-Katz) to several methods that are still undergoing validation. This study was conducted to assess two new parasite identification methods for diagnosing schistosomiasis mans

9. Comparison of the Kato-Katz and Helmintex methods for the diagnosis of schistosomiasis in a low-intensity transmission focus in Bandeirantes, Paraná, southern Brazil
The diagnosis of schistosomiasis is problematic in low-intensity transmission areas because parasitological methods lack sensitivity and molecular methods are neither widely available nor extensively validated. Helmintex is a method for isolating eggs from large faecal samples. We report preliminary results of a comparative evaluation of the Helmintex and Ka

10. AVALIAÇÃO DOS FATORES SÓCIOECONÔMICOS, AMBIENTAIS E IMUNOLÓGICOS ASSOCIADOS À PATOGÊNESE DA ESQUISTOSSOMOSE MANSÔNICA NA ÁREA ENDÊMICA DE ILHA DAS FLORES, SERGIPE. / EVALUATION OF SOCIOECONOMIC FACTORS, ENVIRONMENTAL AND IMMUNOLOGICAL FACTORS ASSOCIATED WITH THE PATHOGENESIS OF SCHISTOSOMIASIS MANSONI IN THE ENDEMIC AREA ISLAND OF FLOWERS, SERGIPE.
Schistosomiasis is an important endemic disease worldwide, affecting over 200 million people. The city of Flores Island, Sergipe, is situated 135 km from the capital, North of the State and has 8,598 inhabitants. Has an extensive irrigation area, where there are many species of snails Biomphalaria glabrata and Biomphalaria straminea. The objectives were to e

11. Evaluation of two coproscopic techniques for the diagnosis of schistosomiasis in a low-transmission area in the state of Minas Gerais, Brazil
This population study, which evaluated two parasitological methods for the diagnosis of schistosomiasis mansoni, was performed in a low-transmission area in Pedra Preta, Montes Claros, Minas Gerais, Brazil. A total of 201 inhabitants of the rural area participated in this research. Four stool samples were obtained from all participants and analysed using the

12. Diagnostico molecular da Leishmaniose visceral canina: avaliação do swab conjuntival em cães assintomáticos e em cães vacinados / Molecular diagnosis of canine visceral leishmaniasis: conjunctival swab evaluation in asymptomatic dogs and vaccinated dogs
The epidemiological control of visceral Leishmaniasis (VL) in Brazil involves the elimination of infected dogs. Therefore, reliable diagnostic tests are essential to prevent the transmission of the disease or unnecessary culling of dogs. The VL control in Brazil is based on serological surveys, nevertheless serologic assays present problems related to sensit
