Ecoepidemiologia da esquistossomose mansoni em áreas da transposição do Rio São...
Pinheiro, Marta Cristhiany CunhaThe schistosomiasis affects about 240 million people in 78 countries. In Brazil, is estimated 1,5 million infected, with approximately 25 million living in risk areas Ceará has a medium positive rate of 0,57%, in low focal endemicity. Some states in the Northeast go through a broad eco-bio-social intervention created by the São Francisco's River Integration Project (Projeto de Integração do Rio São Francisco - ...
Performance of an ultra-sensitive assay targeting the circulating anodic antige...
Sousa, Mariana Silva; Dam, Govert J. van; Pinheiro, Marta Cristhiany Cunha; Dood, Claudia J. de; Peralta, Jose Mauro; Peralta, Regina Helena SaramagoTechniques with high sensitivity and specificity are required for an accurate diagnosis in low-transmission settings, where the conventional parasitological methods are insensitive. We determined the accuracy of an up-converting phosphor-lateral flow circulating anodic antigen (UCP-LF CAA) assay in urine and serum for Schistosoma mansoni diagnosis in low-prevalence settings in Ceará, Brazil, before and after pr...
Controle da esquistossomose em municípios cearenses envolvidos na integração do...
Pinheiro, Marta Cristhiany Cunha; Silva Filho, José Damião da; Sousa, Mariana Silva; Castro, Issis Maria Nogueira deAs ações de controle e vigilância da esquistossomose dos Programas de Controle da Esquistossomose (PCE) têm grande relevância, em especial em contextos de grandes intervenções ambientais como o Projeto de Integração do Rio São Francisco (PISF), que afetará a dinâmica de transmissão. O objetivo desse estudo foi avaliar o desenvolvimento das ações do PCE em municípios da região Sul do Estado do Ceará que serão di...
Identification of Biomphalaria sp. and other freshwater snails in the large-sca...
Bezerra, Fernando Schemelzer de Moraes; Pinheiro, Marta Cristhiany Cunha; Silva Filho, José Damião da; Castro, Issis Maria Nogueira deThe wide eco-bio-social intervention generated by the SaoFrancisco River Integration Project (PISF) may contribute to the dispersion or introduction of schistosomiasis intermediate hosts in areas without prior recording. The objective was to characterize the limnic malacofauna and its distribution along watersheds involved in the PISF. A cross-sectional study based on the collection of mollusks from 33 water bo...

Detection of schistosomiasis in an area directly affected by the São Francisco ...
Silva Filho, José Damião da; Pinheiro, Marta Cristhiany Cunha; Sousa, Mariana Silva; Gomes, Vivian da Silva; Castro, Issis Maria Nogueira deINTRODUCTION: 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 (aged 7-14 years) and workers from the construction site in an area unde...
Evaluating a point-of-care circulating cathodic antigen test (POC-CCA) to detec...
Bezerra, Fernando Schemelzer Moraes; Leal, Joames Kauffimann Freitas; Sousa, Mariana Silva; Pinheiro, Marta Cristhiany CunhaSchistosomiasis is still a public health problem in Brazil. The Kato-Katz test is the most frequently used diagnostic method for Schistosoma mansoni infection. However, it lacks sensitivity in areas of low prevalence. We have assessed the positivity rate of S. mansoni infection in Bananeiras, a village on Capistrano, Ceara, Brazil by performing a point-of-care test in urine to determine the circulating cathodic...
Spatiotemporal patterns of schistosomiasis : related deaths, Brazil, 2000–2011
Martins-Melo, Francisco Rogerlândio; Pinheiro, Marta Cristhiany Cunha; Ramos Júnior, Alberto Novaes; Alencar, Carlos HenriqueWe analyzed spatiotemporal patterns of 8,756 schistosomiasis- related deaths in Brazil during 2000–2011 and identified high-risk clusters of deaths, mainly in highly schistosomiasis- endemic areas along the coast of Brazil’s Northeast Region. Schistosomiasis remains a neglected public health problem with a high number of deaths in disease-endemic and emerging focal areas.
Increased detection of schistosomiasis with Kato-Katz and SWAPIgG- ELISA in a N...
Pinheiro, Marta Cristhiany Cunha; Oliveira, Sara Menezes de; Hanemann, Ana Lúcia de Paula; Queiroz, José Ajax NogueiraIntroduction: The laboratory diagnosis of schistosomiasis is based mainly on the detection of parasite eggs in stool samples through the Kato-Katz (KK) technique, reading one slide by test. However, a widely known limitation of parasitological methods is reduced sensitivity, particularly in low endemic areas. Methods: To increase sensitivity, we conducted further slide readings from the same stool sample using ...
Avaliação de três métodos coproscópicos para diagnóstico da esquistossomose man...
Pinheiro, Marta Cristhiany CunhaThe Schistosomiasis is endemic in 76 countries and territories. In mid 2003, it was estimated that 779 million people were within the population at risk for schistosomiasis, 207 million people were infected. The laboratory diagnosis of schistosomiasis can be accomplished through methods for parasites, ranging from classics (Kato-Katz), a few that are still undergoing validation. This study was conducted to eval...
