1. Where, when, and how the diagnosis of human visceral leishmaniasis is defined: answers from the Brazilian control program
BACKGROUND Timely diagnosis is recommended by the Brazilian Visceral Leishmaniasis (VL) Surveillance and Control Program to reduce case fatality. Attempts at assessing this topic in Brazil are scarce. OBJECTIVE This study aimed to describe where, when, and how the diagnosis of VL has been performed in a Brazilian endemic setting. METHODS Data of all au

2. Chronic Cystoisospora belli infection in an HIV/AIDS patient treated at the specialized assistance service in Porto Velho County - Rondônia.
Abstract Cystoisospora belli infection manifests as diarrhea, and can potentially progress to malabsorption in HIV patients. Here, we report a case of C. belli infection in an HIV/AIDS patient with chronic diarrhea symptoms for at least 2 years. Coproscopic analyses based on direct technique and modified Ziehl-Neelsen technique without a commercial kit were

3. Improving the reference standard for the diagnosis of canine visceral leishmaniasis: a challenge for current and future tests
BACKGROUND Studies aimed at validating canine visceral leishmaniasis diagnostic tests present heterogeneous results regarding test accuracy, partly due to divergences in reference standards used and different infection evolution periods in animals. OBJECTIVE This study aimed to evaluate the accuracy of the rapid test-dual path platform (TR-DPP) (Biomangu

4. Cardiac Evaluation in the Acute Phase of Chagas’ Disease with Post-Treatment Evolution in Patients Attended in the State of Amazonas, Brazil
Resumo Fundamento: Nas últimas duas décadas, um novo perfil epidemiológico da Doença de Chagas (DC) foi registrado na Amazônia brasileira, onde a transmissão oral foi indicada como responsável pelo aumento dos casos agudos. No estado do Amazonas, foram registrados cinco surtos da doença desde 2004. As manifestações cardíacas nesses casos podem se

5. 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

6. Sexual transmission of American trypanosomiasis in humans: a new potential pandemic route for Chagas parasites
BACKGROUND The Trypanosoma cruzi infection endemic in Latin America has now spread to several countries across four continents; this endemic involves triatomine vector-free protists. We hypothesised that the sexual transmission of T. cruzi contributes to the ongoing spread of Chagas disease. OBJECTIVES A short-term longitudinal study was conducted to eva

7. Avaliação da confiabilidade entre dois observadores em exames citopatológico e imunocitoquímico de aspirado de medula óssea no diagnóstico da leishmaniose visceral canina
ABSTRACT Visceral leishmaniasis is a zoonosis in which the dog appears as the main source of infection in urban areas. Its diagnosis is complex and the cytopathological exam is a fast and cheap alternative to parasite direct visualization and its sensitivity can be increased by immunocytochemistry, though with a higher cost. The accuracy of such methods is d

8. Domestic, peridomestic and wild hosts in the transmission of Trypanosoma cruzi in the Caatinga area colonised by Triatoma brasiliensis
The role played by different mammal species in the maintenance of Trypanosoma cruzi is not constant and varies in time and place. This study aimed to characterise the importance of domestic, wild and peridomestic hosts in the transmission of T. cruzi in Tauá, state of Ceará, Caatinga area, Brazil, with an emphasis on those environments colonised by Triatom

9. Evaluation of parasitological examination, kDNA polymerase chain reaction and rK39-based immunochromatography for the diagnosis of visceral leishmaniasis in seropositive dogs from the screening-culling program in Brazil
Introduction Dogs play a primary role in the zoonotic cycle of visceral leishmaniasis (VL). Therefore, the accurate diagnosis of infected dogs, primarily asymptomatic dogs, is crucial to the efficiency of VL control programs. Methods We investigated the agreement of four diagnostic tests for canine visceral leishmaniasis (CVL): parasite detection, either

10. Assessing bovine babesiosis in Rhipicephalus (Boophilus) microplus ticks and 3 to 9-month-old cattle in the middle Magdalena region, Colombia
Babesia sp. is a protozoan hemoparasite that affects livestock worldwide. The Colombian Middle Magdalena is an enzootic region for babesiosis, but there is no previous research providing detail on its transmission cycle. This study aims to assess some Babesia sp. infection indicators in cattle and ticks from the area, by using direct microscopic and molecula

11. Enteroparasitoses em comunidades indígenas brasileirass / Intestinal parasites in Brazilian indigenous communities
The parasitic infections are the major public health problems, presenting an endemic form in several areas of Brazil. They may present narrow relationship with social-demographical and environmental factors, such as: social-economical precarious conditions, consumption contaminated water, deficient nutritional condition of individuals and others, being frequ

12. 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
