1. Variação geográfica de Hylaeamys yunganus (Thomas, 1902) na América do Sul (Rodentia: Sigmodontinae) / Geographic variation and phylogeography of Hylaeamys yunganus (Thomas, 1902) (Rodentia: Sigmodontinae)
Hylaeamys yunganus is a rodent of the Oryzomyini tribe presenting samples distributed through the Amazon rainforests and occupies a wide altitudinal gradient, which extends from sea level up to ca. 2,000m. Information available in the literature suggests that populations of H. yunganus from Venezuela, Colombia, Ecuador, Peru and western Brazil have large bod

2. Biodiversidade dos helmintos parasitos dos roedores simpátricos Oligoryzomys nigripes e Akodon spp. (Rodentia: Sigmodontinae), na Mata Atlântica, / Biodiversity of helminth parasites in the sympatric rodents Oligoryzomys nigripes and Akodon spp. (Rodentia: Sigmodontinae), in the Atlantic Forest, Teresópolis,
O objetivo deste trabalho foi descrever a composição e estrutura da comunidade helmíntica comparando a comunidade componente e a infracomunidade dos helmintos das populações de roedores simpátricos Akodon spp. e Oligoryzomys nigripes na Mata Atlântica e os diferentes tamanhos de fragmentos e a reserva do Parque Nacional da Serra dos Órgãos (PARNASO)

3. The use of PCR-RFLP as an identification tool for three closely related species of rodents of the genus Akodon (Sigmodontinae, Akodontini)
Three cryptic species of the rodent Akodon (A. cursor, A. montensis and Akodon sp.) were analyzed. The two former species are sympatric in the Brazilian states of São Paulo, Rio de Janeiro and Minas Gerais, where hybrids have already been found. The third species, Akodon sp., occurs in an isolated area in Central Brazil. The identification of these species

4. A comparative parasitologic study on Biomphalaria glabrata snail and C3H/He mice infected with human and murine isolates of Schistosoma mansoni derived from Sumidouro, Rio de Janeiro, Brazil
Experiments were carried out to analyze the biological characteristics of two sympatric isolates of Schistosoma mansoni derived from humans and murines in a low endemic transmission area (Sumidouro county, state of Rio de Janeiro, Brazil). Sympatric reared-laboratory Biomphalaria glabrata and C3H/He mice were used as experimental hosts. Parameters assessed c

5. Cercarial Chaetotaxy and Sex Differentiation of Schistosoma mansoni Deriving from Humans and Nectomys squamipes (Muridae: Sigmondontinae) in Brazil
A comparative study was made between sympatric isolates of Schistosoma mansoni: one from a wild rodent (R) Nectomys squamipes and another one from humans (H) isolated from a low endemic schistosomiasis transmission area in Brazil. Our purpose was to detect differences between them concerning chaetotaxy (number and pattern of distribution of the argentophilic

6. Genetic Interaction between Distinct Dobrava Hantavirus Subtypes in Apodemus agrarius and A. flavicollis in Nature
Dobrava virus (DOBV) occurs in two different rodent species, Apodemus flavicollis (DOBV-Af) and A. agrarius (DOBV-Aa). We sequenced the S and M genomic segments from sympatric DOBV-Af and DOBV-Aa strains which fell into two distinct genetic lineages. Molecular phylogenetic analyses gave evidence for genetic reassortment between S and M segments of DOBV-Af an
