| allpahuayo virus: a newly recognized arenavirus (arenaviridae) from arboreal rice rats (oecomys bicolor and oecomys paricola) in northeastern peru. | allpahuayo virus was initially isolated from arboreal rice rats (oecomys bicolor and oecomys paricola) collected during 1997 at the allpahuayo biological station in northeastern peru. serological and genetic studies identified the virus as a new member of the tacaribe complex of the genus arenavirus. the small (s) segment of the allpahuayo virus prototype strain clhp-2098 (accession no. ay012686) was sequenced, as well as that of sympatric isolate clhp-2472 (accession no. ay012687), from the sam ... | 2001 | 11384226 |
| a new karyological variant of oecomys (rodentia: sigmodontinae) and its phylogenetic relationship based on molecular data. | a new karyological variant of the sigmodontinae genus oecomys was detected in specimens from brazilian pantanal. karyologic analyses showed 2n = 72 and fn = 90, which differs from all known chromosomal complements of the genus. this new karyomorph showed distinctive morphological attributes and could not be attributed to any described oecomys species. molecular analysis using cytochrome-b sequence data suggested the monophyly of oecomys. maximum-likelihood analyses placed the oecomys sp. haploty ... | 2003 | 12723035 |
| intense genomic reorganization in the genus oecomys (rodentia, sigmodontinae): comparison between dna barcoding and mapping of repetitive elements in three species of the brazilian amazon. | oecomys thomas, 1906 is one of the most diverse and widely distributed genera within the tribe oryzomyini. at least sixteen species in this genus have been described to date, but it is believed this genus contains undescribed species. morphological, molecular and cytogenetic study has revealed an uncertain taxonomic status for several oecomys species, suggesting the presence of a complex of species. the present work had the goal of contributing to the genetic characterization of the genus oecomy ... | 2016 | 27830049 |
