[Seroepidemiological survey of human cysticercosis in a municipality of Piauí State, Northeast Brazil].

As part of parasitological studies in the area surrounding the Serra da Capivara National Park, Piauí State, Northeast Brazil, from 1999 to 2001, the current study aimed to evaluate the epidemiological profile of human cysticercosis in the Municipality of João Costa. Clinical and epidemiological data were obtained, and blood samples were drawn for immunoenzymatic serological tests (ELISA and Western blot), using Taenia crassiceps as the antigen. The first stage, in 1999, investigated 169 individuals with a confirmed history or suspicion of infection/disease involving the teniasis/cysticercosis complex, along with the family members.

[Study of the infection and morbidity of Chagas' disease in municipality of João Costa: National Park Serra da Capivara, Piauí, Brazil].

In order to investigate aspects of the infection and morbidity of Chagas' disease in the municipality of João Costa, Piauí State, Brazil, we carried out a serological survey to detect anti-Trypanosoma cruzi antibodies in 2,080 individuals, by indirect immunofluorescence, indirect hemagglutination and ELISA. A total of 189 seropositive and 141 seronegative patients were evaluated by anamnesis, physical exam and electrocardiogram (EKG). The parasitaemia of 106 chagasic patients was evaluated by indirect xenodiagnosis and PCR (polymerase chain reaction).
