The diagnostic potential of circulating IgM and IgA antibodies against Schistosoma mansoni gut-associated antigens detected by the immunofluorescence test (IFT) on adult worm paraffin sections was evaluated comparatively to the fecal parasitological method, for epidemiological purposes in low endemic areas for schistosomiasis. Blood samples were collected on filter paper from two groups of schoolchildren living in two different localities of the municipality of Itariri (São Paulo, Brazil) with different histories and prevalences of schistosomiasis. The parasitological and serological data were compared to those obtained for another group of schoolchildren from a non-endemic area for schistosomiasis. The results showed poor sensitivity of the parasitological method in detecting individuals with low worm burden and indicate the potential of the serological method as an important tool to be incorporated into schistosomiasis control and vigilance programs for determining the real situation of schistosomiasis in low endemic areas.
Durante o período de janeiro de 1987 a dezembro de 1988, procurou-se investigar a ocorrência de larvas de Strongyloides stercoralis em 554 pacientes acometidos pela síndrome de imunodeficiência adquirida, comparativamente a um grupo controle formado por 142 pacientes portadores de outras moléstias infecciosas. Os dois grupos estudados foram compostos por pacientes do sexo masculino, internados no Hospital Emílio Ribas, cujas amostras de fezes foram submetidas aos métodos de sedimentação espontânea e de RUGAI e cols. Os resultados obtidos após análise estatística revelaram prevalência semelhante nos dois grupos estudados (p > 0,05).
Monthly and yearly reports of the Seção de Enteroparasitoses of the Instituto Adolfo Lutz (São Paulo, SP, Brazil) from 1960 to 1989 with 1,519,730 parasitological stool examinations were studied. There were also 355 identifications of Taenia sp. proglottids. Using Hoffman, Pons & Janer's method, 7,663 (0.5%) cases of taeniasis were diagnosed, and 311 (87.60%) of the 355 proglottids were on easy terms to be specified, 273 (87.80%) of them were from Taenia saginata.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
