| host-species transferrin receptor 1 orthologs are cellular receptors for nonpathogenic new world clade b arenaviruses. | 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 we show that pseudotyped viruses bearing the surface glycoprotein (gp) of amav or tcrv can infect cells using the tfr1 orthologs of several ma ... | 2009 | 19343214 |
| andes hantavirus variant in rodents, southern amazon basin, peru. | we investigated hantaviruses in rodents in the southern amazon basin of peru and identified an andes virus variant from neacomys spinosus mice. this finding extends the known range of this virus in south america and the range of recognized hantaviruses in peru. further studies of the epizoology of hantaviruses in this region are warranted. | 2014 | 24447689 |
| xapuri virus, a novel mammarenavirus: natural reassortment and increased diversity between new world viruses. | mammarenavirus rna was detected in musser's bristly mouse (neacomys musseri) from the amazon region, and this detection indicated that rodents were infected with a novel mammarenavirus, with the proposed name xapuri virus (xapv), which is phylogenetically related to new world clade b and clade c viruses. xapv may represent the first natural reassortment of the arenaviridae family and a new unrecognized clade within the tacaribe serocomplex group. | 2018 | 29959319 |
| revision of <i>neacomys spinosus</i> (thomas, 1882) (rodentia: cricetidae) with emphasis on peruvian populations and the description of a new species. | the large spiny mouse neacomys spinosus (thomas, 1882) has been considered the widest ranging species of the genus, occurring in southern colombia, eastern peru, western brazil and northern bolivia. the morphological variation between subspecies and populations of n. spinosus has been noted; nonetheless, this variation has not been assessed in a morphological or molecular context. here, we present a taxonomic revision of neacomys spinosus s.l. using qualitative and quantitative morphological ana ... | 2017 | 28610159 |
| bolivian ectoparasites: a new species of laelapine mite (acari: parasitiformes, laelapidae) from the rodent neacomys spinosus. | laelaps neacomydis n. sp. is described from the pelage of the rodent neacomys spinosus collected in bolivia. collection records from northern brazil, southeastern peru, and central bolivia indicate its wide distribution across amazonas associated with rodents of the genus neacomys. the formal taxonomic description and illustrations are derived from the adults (female and male). two larger species of laelapine mites, gigantolaelaps intermedius and l. boultoni, infest the same hosts at the same lo ... | 2005 | 15856871 |
| [structural characteristics of certain rodents spines (rodentia: myomorpha, hystricomorpha)]. | the architectonics of spines and hair was studied in neacomys spinosus, arvicanthis somalicus, leopoldamys sabanus, l. edwardsi, maxomys moi, m. surifer, niviventer fulvescens, n. confucianus, n. cremoriventer, acomys cahirinus, a. somalica, hystrix indica, h. cristata, atherurus macrourus, erethizon dorsatum, proechimys steerei, and lonchotrix emiliae. the presence of a dorsal longitudinal furrow covered by a modified cuticle is a common structural feature of spines in all studied species excep ... | 2016 | 11525125 |
