Improving the reference standard for the diagnosis of canine visceral leishmani...
Teixeira, Ana Izabel Passarella; Silva, Debora Marcolino; Vital, Tamires Emanuele; Nitz, Nadjar; Carvalho, Bruna Caroline Véras deBACKGROUND 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) (Biomanguinhos®), EIE-Leishmaniose-Visceral-Canina-Biomanguinhos (E...
Transmission control of schistosomiasis mansoni in a low endemicity area throug...
Carneiro, Nídia Francisca de Figueiredo; Caldeira, Antônio Prates; Katz, Naftale; Oliveira, Áureo Almeida de; Siqueira, Liliane Maria VidalA prospective cohort study with rigorous searching for schistosomiasis cases was conducted among residents of Pedra Preta, Montes Claros, Minas Gerais State, Brazil, seven years after an intervention. Kato-Katz (KK), Saline Gradient, Miracidia Hatch and Polymerase Chain Reaction (PCR) were used as the diagnostic methods in 2008. In the period of 2013-2016, 175 patients remaining in the area were examined using ...
Effectiveness of the Brazilian Visceral Leishmaniasis Surveillance and Control ...
Rocha, Iara Caixeta Marques da; Santos, Letícia Helena Marques dos; Vital, Wendel Coura; Cunha, Gisele Macedo Rodrigues da; Magalhães, Fernanda do CarmoBackground Control strategies adopted by the Brazilian Visceral Leishmaniasis Surveillance and Control Programme (VLSCP) include identifying and culling seropositive infected dogs, early diagnosis and treatment of human cases, chemical control of the vector and population awareness. This study evaluated the effectiveness of the VLSCP on the prevalence and incidence rates of Leishmania infantum in children resid...
Genetic homogeneity among Leishmania (Leishmania) infantum isolates from dog an...
Silva, Thais Almeida Marques da; Gomes, Luciana Inácia; Oliveira, Edward; Vital, Wendel Coura; Silva, Letícia de AzevedoBackground: Certain municipalities in the Belo Horizonte Metropolitan Area (BHMA), Minas Gerais, Brazil, have the highest human visceral leishmaniasis (VL) mortality rates in the country and also demonstrate high canine seropositivity. In Brazil, the etiologic agent of VL is Leishmania (Leishmania) infantum. The aim of this study was to evaluate the intraspecific genetic variability of parasites from humans and...
THE SCHISTOSOMULA TEGUMENT ANTIGEN AS A POTENTIAL CANDIDATE FOR THE EARLY SEROL...
Grenfell, Rafaella; Martins, Watson; Silva-Moraes, Vanessa; Araujo, Neusa; Oliveira, Edward; Fonseca, Cristina; Coelho, Paulo Marcos ZechIf Schistosoma mansoni infection could be detected in its early stages, especially before the egg deposition in the host tissues, the development of severe pathologic lesions could be efficiently prevented. We therefore developed an indirect enzyme-linked immunosorbent assay based on the detection of specific IgG against schistosomula antigens (ELISA-SmTeg). The assay was applied in sera samples from non-infect...
