Rio de Janeiro, RJ, Brasilhe evaluation of the role of rodents as natural hosts of Schistosoma mansoni was studied at the Pamparrão Valley, Sumidouro, RJ, with monthly captures and examination of the animals. Twenty-three Nectomys squamipes and 9 Akodom arviculoides with a shistosomal infection rate of 56.5% and 22.2% respectively eliminated a great majority of viable eggs. With a strain isolated from one of the naturally infected N. squamipes, we infected 75% of simpatric Biomphalaria glabrata and 100% of albino Mus musculus mice. The adult worms, isolated from N. squamipes after perfusion were located mainly in the liver (91.5%) and the mesenteric veins (8.5%). The male/female proportion was 2:1. The eggs were distributed on small intestine segments (proximal, medial and distal portions) and the large intestine without any significant differences in egg concentration of these segments. In A. arviculoides, the few eggs eliminated by the stools were viable and there was litlle egg retention on intestinal segments. Considering the ease to complete S. mansoni biological cycle in the Nectomys/Biomphalaria/Nectomys system under laboratory conditions, probably the same is likely to occur in natural conditions. In support to this hypotesis there are also the facts that human mansonic shistosomiasis has a very low prevalence in Sumidouro and endemicity among the rodents has not changed even after repetead treatments of the local patients. Based on our experiments, we conclude that N. squamipes has become a natural host of S. mansoni and possibly may participate in keeping the cycle of schistosomiasis transmission at Pamparrão Valley.Schistosoma mansoniWild RodentsNectomys squamipesNatural InfectionAkodon arviculoidesSchistosoma mansoniRoedoresInfecçãoinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZORIGINALNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdfNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdfapplication/pdf308130https://www.arca.fiocruz.br/bitstream/icict/3725/1/Natural%20infection%20of%20wild%20rodents%20by%20Schistosoma%20mansoni%20parasitological%20aspects.pdfbcb9acbae612b21d4f9e8d4a2e9946cfMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81648https://www.arca.fiocruz.br/bitstream/icict/3725/2/license.txte095249ac7cacefbfe39684dfe45e706MD52TEXTNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdf.txtNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdf.txtExtracted texttext/plain6https://www.arca.fiocruz.br/bitstream/icict/3725/5/Natural%20infection%20of%20wild%20rodents%20by%20Schistosoma%20mansoni%20parasitological%20aspects.pdf.txt6d93d3216dc4a7f5df47d4876fbec4d3MD55THUMBNAILNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdf.jpgNatural infection of wild rodents by Schistosoma mansoni parasitological aspects.pdf.jpgGenerated Thumbnailimage/jpeg2460https://www.arca.fiocruz.br/bitstream/icict/3725/4/Natural%20infection%20of%20wild%20rodents%20by%20Schistosoma%20mansoni%20parasitological%20aspects.pdf.jpg5eef01f61198c4d1e3b980eda8c96d65MD54icict/37252018-04-06 08:57:59.559oai:www.arca.fiocruz.br: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Repositório InstitucionalPUBhttps://www.arca.fiocruz.br/oai/requestrepositorio.arca@fiocruz.bropendoar:21352018-04-06T11:57:59Repositório Institucional da FIOCRUZ (ARCA) - Fundação Oswaldo Cruz (FIOCRUZ)false
