| amazonian phylogeography: mtdna sequence variation in arboreal echimyid rodents (caviomorpha). | patterns of evolutionary relationships among haplotype clades of sequences of the mitochondrial cytochrome b dna gene are examined for five genera of arboreal rodents of the caviomorph family echimyidae from the amazon basin. data are available for 798 bp of sequence from a total of 24 separate localities in peru, venezuela, bolivia, and brazil for mesomys, isothrix, makalata, dactylomys, and echimys. sequence divergence, corrected for multiple hits, is extensive, ranging from less than 1% for c ... | 1993 | 8136924 |
| trypanosoma (megatrypanum) lainsoni n. sp. from mesomys hispidus (rodentia: echimyidae) in brazil: trypomastigotes described from experimentally infected laboratory mice. | we report the detection, isolation and description of trypanosoma (megatrypanum) lainsoni n. sp. from a caviomorph rodent, mesomys hispidus (rodentia: echimyidae), obtained in the rio negro region of the state of amazonas, in northern brazil. laboratory-bred white mice (mus musculus) and rats (rattus rattus) were inoculated with large numbers of culture forms by intraperitoneal route, and trypomastigotes appeared in their blood 3-8 days post-inoculation. one single epimastigote was also found in ... | 2013 | 24309069 |
