ABSTRACT
O trabalho foi realizado no intuito de registrar a distribuição geopolítica da Fasciolose Hepática na Ilha de Santiago, Cabo Verde. Durante a avaliação, realizada de maio a junho de 2008, foram registrados tamanho e taxas de infecção do molusco, pH e temperatura da água e taxas de infecção de vertebrados. As amostras de moluscos e de fezes de bovinos foram coletadas, de forma aleatória, em todos os municípios da Ilha de Santiago, com exceção de Tarrafal, e, devidamente embaladas, encaminhadas para o Laboratório do Instituto Nacional de Investigação e Desenvolvimento Agrário (INIDA), onde foram analisadas. As análises demonstraram resultados positivos para a coproscopia de bovinos e a presença do hospedeiro intermediário (Lymnaea natalensis) em todos os municípios visitados. Também ficou demonstrada uma correlação positiva entre a taxa de infecção dos hospedeiros vertebrados e invertebrados, sendo que o maior índice foi registrado no Município de Santa Cruz (72,72%) e o menor no da Praia (16,66%). A taxa de infecção média verificada para os moluscos e os bovinos foi de 51,51% e 37,15%, respectivamente.
A survey was carried out in order to study the geopolitical distribution of fascioliasis on Santiago Island, Cape Verde. During the evaluation, conducted from May to June 2008, measurements were made and recorded regarding the size and infection rates of the snail, pH and water temperature and vertebrate infection rates. Snails and bovine feces samples were collected at random in all municipalities of Santiago Island, except Tarrafal, properly packed, and sent to the Laboratory of National Institute of Agricultural Research and Development (INIDA) where they were analyzed. The results showed positive results for stool examinations of cattle and the presence of an intermediate host (Lymnaea natalensis) in all localities visited. A positive correlation was also found between the vertebrate and invertebrate infection rate, with the highest rate recorded in Santa Cruz (72.72%) and the lowest in Praia (16.66%). The average infection rate observed for the snails and cattle was 51.51% and 37.15%, respectively.

ABSTRACT
The prevalence and clinical forms of Trypanosoma cruzi were evaluated among blood donor candidates attended at a general hospital in Rio de Janeiro, Brazil, from January 1997 to April 1999. The investigation was done by means of the indirect hemagglutination test and was confirmed via ELISA. Data were collected from clinical examinations, conventional electrocardiogram, chest radiography and echocardiography. The results showed that despite Trypanosoma cruzi prevalence of 1.17% (128 patients), mainly in males aged 40 years or over, 70.8% of these patients, mainly males aged 19 to 39 years, demonstrated abnormalities that allowed the diagnosis of cardiopathy and/or esophagopathy. This once again corroborates the importance of Trypanosoma cruzi infection in urban centers.
