Abstract: Small mammals are found naturally infected by Schistosoma mansoni, becoming a confounding factor for control programs of schistosomiasis in endemic areas. The aims of this study were: to investigate the infection rates by S. mansoni on the water-rat Nectomys squamipes during four years in endemic areas of Sumidouro, state of Rio de Janeiro, using mark-recapture technique; to compare two diagnostic methods for schistosomiasis; and to evaluate the effects of the chemotherapy in the human infected population on t… Show more

“…Nectomys squamipes, which is the main non-human definitive host of S. mansoni in Brazil (D'ANDREA et al, 2000), is characterized by its semi-aquatic habits and wide geographic distribution (BONVICINO et al, 2008;MALDONADO et al, 1994;RODRIGUES-SILVA et al, 1992;REY, 1993). Therefore, the occurrence of this semi-aquatic rodent in endemic areas is a factor that makes it difficult to control this zoonosis (SOUZA et al, 1992;D'ANDREA et al, 2000;GENTILE et al, 2006). Cheever et al (1998) reported the formation of hepatic granulomas in mice infected by S. mansoni.…”

“…The data analyzed in this study is part of a long term Brazilian eco-epidemiological program on the role of the water-rat Nectomys squamipes as a wild reservoir of schistosomiasis in a rural area, endemic of Schistosomiasis (Gentile et al 2006). Other ecological studies (D'Andrea et al 1999;Gentile et al 2000;Gentile and Fernandez 1999;D'Andrea et al 2007) were conducted in the same region, but in different localities.…”

“…The present study highlights the importance of water rat as a reservoir host for S. mansoni strains that might contribute to dispersion of schistosomiasis mansoni in Brazil. Moreover, from a public health perspective, if schistosomiasis mansoni control program is to be instituted in areas where water rats are commom, the program should take into account their epidemiological role 13 . More comparative studies are needed to investigate the occurrence of phenotypic plasticity among field S. mansoni strains.…”
