Field mice of the genus Calomys are small, mostly granivorous rodents common to several habitats in South America. To date, phylogenies for the genus have been proposed on the basis of morphological, chromosomal, and biochemical data, often with contradictory results due to incomplete species sampling or methodological shortcomings. In this paper, we(More)
In the probing theatrical opus " Jumpers, " one of the characters created by playwright Tom Stoppard (1972) asks the question: " Is God? " The question is thus phrased, the character explains, because to phrase it in any other way would presuppose an assumption of doubt on the part of the questioner, when in fact an unbiased mind and question is what is(More)
Zoonoses within wild reservoir host populations often occur focally obeying Pavlovskii's rules of "natural nidality". What appears to be a clear example is Bolivian hemorrhagic fever (BHF), a disease endemic to northeastern Bolivia. The etiological agent is Machupo virus (MACV, Arenaviridae). The vertebrate reservoir, identified 30 years ago, was Calomys(More)
In late 1999 and early 2000, an outbreak of hantavirus pulmonary syndrome (HPS) occurred in and around Los Santos, on the Azuero Peninsula of southwestern Panamá. This HPS episode, resulting in 22% case fatality, was linked to the Costa Rican pigmy rice rat, Oligoryzomys fulvescens costaricensis, which harbored a then undescribed hantavirus, Choclo virus.(More)
The ability of a New World (NW) clade B arenavirus to enter cells using human transferrin receptor 1 (TfR1) strictly correlates with its ability to cause hemorrhagic fever. Amapari (AMAV) and Tacaribe (TCRV), two nonpathogenic NW clade B arenaviruses that do not use human TfR1, are closely related to the NW arenaviruses that cause hemorrhagic fevers. Here(More)
Molecular systematics, taxonomy and biogeography of the genus Cavia (Rodentia: Caviidae) Abstract Phylogenetic analyses were conducted on cytochrome b sequence data of the most geographically and taxonomically broad sampling of Cavia taxa to date. Primary objectives included providing the first extensive molecular phylogenetic framework for the genus,(More)
The Neotropics harbors a high diversity of species and several hypotheses have been proposed to account for this pattern. However, while species of forested domains are frequently studied, less is known of species from open vegetation formations occupying, altogether, a larger area than the Amazon Forest. Here we evaluate the role of historical barriers and(More)
We present new records for Bolivian mammals that have been gathered in 1991 and 1992. The first specimen of Chironectes minimus from Bolivia and new localities of distribution for Monodelphis kunsi and Dactylomys boliviensis are reported. Résumé. Nous présentons de nouvelles données sur des mammifères boliviens qui ont été collectés en 1991 et 1992. Nous(More)
in the csp gene of Pkpah-1. Furthermore, the alignment showed 21 variable sites between the genes. Phylogenetic analysis based on SSU rRNA sequences indicated that Pkpah-1 and Pkprk-1 formed a cluster, which was more related to P. knowlesi isolates from Thailand than to isolates from Sarawak, a Malaysian state in Borneo Island (Figure). Another isolate from(More)
Southeast Asia to its knees…, " apparently on the basis of an unsubstantiated report (1). Li et al.'s data confirm that horseshoe bats are a reservoir for a coronavirus related to SARS-CoV found in humans and the virus isolated from palm civets, but this does not make them the reservoir for SARS-CoV. Dobson's linking of bats to emerging diseases caused by(More)
