| the gastrointestinal helminths of rattus niobe (rodentia: muridae) with descriptions of two new genera and three new species (nematoda) from papua new guinea and papua indonesia. | cestodes, to be identified elsewhere, the acanthocephalan moniliformis moniliformis and 15 species of nematode including 2 new genera, a new species and 2 putative new species from the families heligmonellidae and oxyuridae, as well as juveniles and a putative heligmonellid that could not be fully identified, were collected from the digestive tracts of 34 rattus niobe (muridae: murinae: rattini) from papua, indonesia and papua new guinea. the ascaridid, toxocara mackerrasae, the chabertiid cyclo ... | 2016 | 27395168 |
| complete genome sequence of nariva virus, a rodent paramyxovirus. | nariva virus (narpv) was isolated from forest rodents (zygodontomys b. brevicauda) in eastern trinidad in the early 1960s. initial classification within the family paramyxoviridae was based mainly on morphological observations including the structure of nucleocapsids and virion surface projections. here, we report the characterization of the complete genome sequence of narpv. the genome is 15,276 nucleotides in length, conforming to the rule-of-six, and has a genome organization typical of most ... | 2009 | 19104752 |
| resolution of natural groups using iterative assignment tests: an example from two species of australian native rats (rattus). | sympatric individuals of rattus fuscipes and rattus leucopus, two australian native rats from the tropical wet forests of north queensland, are difficult to distinguish morphologically and are often confused in the field. when we started a study on fine-scale movements of these species, using microsatellite markers, we found that the species as identified in the field did not form coherent genetic groups. in this study, we examined the potential of an iterative process of genetic assignment to s ... | 2001 | 11555250 |
| kappa-chain constant-region gene sequences in genus rattus: coding regions are diverging more rapidly than noncoding regions. | we have determined the nucleotide sequence of a 1,200-base pair (bp) genomic fragment that includes the kappa-chain constant-region gene (c kappa) from two species of native australian rodents, rattus leucopus cooktownensis and rattus colletti. comparison of these sequences with each other and with other rodent c kappa genes shows three surprising features. first, the coding regions are diverging at a rate severalfold higher than that of the nearby noncoding regions. second, replacement changes ... | 1984 | 6443796 |
