The influence of <jats:italic>Schistosoma mansoni<\/jats:italic> on a population of <jats:italic>Nectomys squamipes<\/jats:italic> was studied by capture-recapture (1st phase, from June 1991 to November 1995) and removal (2nd phase, from April 1997 to March 1999) studies \nat Sumidouro, Rio de Janeiro, Brazil. During both phases coproscopic examinations were performed. At the 2nd phase \nthe rodents were perfused and worms were counted. The population dynamics of parasites was studied. During the 1st \nphase, female reproductive parameters, longevity, recruitment and survivorship rates and migration patterns were studied \nin relation to schistosome prevalence. Water contamination (source of <jats:italic>miracidia<\/jats:italic>), abundance intermediate host and rodent \nmigration were related to prevalence. The <jats:italic>N. squamipes<\/jats:italic> population was not obviously influenced by the infection, as shown \nby the high number of reproductive infected females, high longevity of infected individuals and the absence of a \nrelationship between recruitment or survivorship rates and the intensity of schistosome infection. The data indicate that \n<jats:italic>N. squamipes<\/jats:italic> can increase transmission of <jats:italic>S. mansoni<\/jats:italic> in endemic areas and carry it to non-infected areas. Furthermore, \nthis rodent can be used as an indicator of a transmission focus.<\/jats:p>","DOI":"10.1017\/s0031182099005892","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:30:22Z","timestamp":1027762222000},"page":"573-582","source":"Crossref","is-referenced-by-count":47,"title":["The parasitism of <i>Schistosoma mansoni<\/i> \n(Digenea\u2013Trematoda) in a naturally infected population of \nwater rats, <i>Nectomys squamipes<\/i> (Rodentia\u2013Sigmodontinae) \nin Brazil"],"prefix":"10.1017","volume":"120","author":[{"given":"P.
