| We report here the complete genomic sequence of the Chilean human isolate of Andes virus CHI-7913. The S, M, and L genome segment sequences of this isolate are 1,802, 3,641 and 6,466 bases in length, with an overall GC content of 38.7%. These genome segments code for a nucleocapsid protein of 428 amino acids, a glycoprotein precursor protein of 1,138 amino acids and a RNA-dependent RNA polymerase of 2,152 amino acids. In addition, the genome also has other ORFs coding for putative proteins of 34 to 103 amino acids. The encoded proteins have greater than 98% overall similarity with the proteins of Andes virus isolates AH-1 and Chile R123. Among other sequenced Hantavirus, CHI-7913 is more closely related to Sin Nombre virus, with an overall protein... |

| Home range size and habitat use of seropositive Oryzomys palustris, primary host for the Bayou strain of hantavirus, were compared to that of seronegative individuals from March 2002 - August 2003 in a longitudinal field population study. There were significant macrohabitat associations with serological status, but selection for most microhabitat variables did not differ between seropositive and seronegative animals. Seropositive adult males moved farther (had larger home ranges) than did seronegatives and were larger in terms of mass and testes size. These patterns may reflect the influence of infection on rodent ecology in terms of dominance and access to preferred habitats. |

| El riesgo de infección con Hantavirus depende de factores, que determinan una probabilidad de contagio con los reservorios, tales como: (a) la estructura vegetacional y el uso del suelo como un escenario primario, donde los factores específicos de composición, estructura y densidad de la vegetación detallan elementos relacionados con el habitat de los reservorios. (b) La existencia de poblaciones de roedores reservorio. (c) Establecimientos humanos, como disponibilidad y densidad de caminos, áreas habitadas o de presencia humana (e.g., casas, bodegas). Estos tres factores, habitat (probabilidad de ocurrencia del reservorio), roedores seropositivos (peligro de contagio) y humanos (población expuesta), conjugados, proporcionan los elementos de juicio... |

| La Octava Región de Chile corresponde a la segunda región con el mayor número de casos de Síndrome Cardiopulmonar por Hantavirus (SCPH). Por tal motivo se realizó un estudio para detectar la presencia de anticuerpos contra hantavirus en roedores y su distribución local en la Octava Región. El estudio comprendió las cuatro provincias de la región y consideró once sitios de muestreo. Se capturaron siete especies de roedores, Abrothrix olivaceus fue la más abundante seguida de Oligoryzomys longicaudatus. De los 300 roedores analizados, cinco ejemplares (1,66 %) resultaron ser positivos a hantavirus y correspondieron a tres especies de sigmodontinos: a saber, Loxodontomys micropus, que corresponde al único registro de este tipo para la especie en Chile,... |

| At present, 20 species of Oligoryzomys (Rodentia, Sigmodontinae) are recognized in the Neotropical region, most of them distinguished by their karyotypes, which fluctuates between 46-70 chromosomes. Two species are currently recognized in Chile, Oligoryzomys longicaudatus (Bennet, 1832; "colilargo" or the long-tailed pygmy rice rat; 2n = 56), which ranges from 27° to approximately 51° S, and O. magellanicus (Bennet, 1836; Magellanic pygmy rice rat; 2n = 54), south of 51° S in the Patagonian region of Chile and Argentina. As part of an ongoing research on the southern Patagonia of Chile, we report the results of small mammal samplings in six localities. We karyotyped 28 specimens and we also sequenced the hypervariable mtDNA region I in 22 individuals,... |
