| chromosomal phylogeny of muridae: a study of 10 genera. | the karyotypes of 10 different species of the family muridae (acomys airensis, arvicanthis niloticus, hylomyscus stella, malacomys longipes, mastomys huberti, myomys daltoni, mus musculus, rattus norvegicus, thamnomys gazellae, and uranomys ruddi) are compared by different banding techniques. from a reconstruction of the presumed ancestral karyotype of the muridae the sequence of the various rearrangements leading to the present karyotypes is proposed in order to determine their phylogenetic rel ... | 1983 | 6617265 |
| lassa serology in natural populations of rodents and horizontal transmission. | lassa virus causes hemorrhagic fever in west africa. previously, we demonstrated by pcr screening that only the multimammate mouse, mastomys natalensis, hosts lassa virus in guinea. in the present study, we used the same specimen collection from 17 villages in coastal, upper, and forest guinea to investigate the lassa virus serology in the rodent population. the aim was to determine the dynamics of antibody development in m. natalensis and to detect potential spillover infections in other rodent ... | 2014 | 25229705 |
| molecular phylogeny of myomys/stenocephalemys complex and its relationships with related african genera. | partial 16s rrna mitochondrial gene sequences were used to infer the phylogenetic relationships among stenocephalemys albocaudata, s. griseicauda and myomys albipes, three closely related ethiopian endemic murines and a selection of related species (myomys daltoni, praomys delectorum, mastomys natalensis, hylomyscus kaimosae, and colomys goslingi) from other african regions. the obtained phylogeny confirms the close relationship between m. albipes and the two stenocephalemys species, but it also ... | 2001 | 11336808 |
| plio-pleistocene history of west african sudanian savanna and the phylogeography of the praomys daltoni complex (rodentia): the environment/geography/genetic interplay. | rodents of the praomys daltoni complex are typical inhabitants of the sudanian savanna ecosystem in western africa and represent a suitable model for testing the effects of quaternary climatic oscillations on extant genetic variation patterns. phylogeographical analyses of mitochondrial dna sequences (cytochrome b) across the distribution range of the complex revealed several well-defined clades that do not support the division of the clade into the two species currently recognized on the basis ... | 2010 | 20958815 |
| movement patterns of small rodents in lassa fever-endemic villages in guinea. | the natal multimammate mouse (mastomys natalensis) is the reservoir host of lassa arenavirus, the etiological agent of lassa fever in humans. because there exists no vaccine for human use, rodent control and adjusting human behavior are currently considered to be the only options for lassa fever control. in order to develop efficient rodent control programs, more information about the host's ecology is needed. in this study, we investigated the spatial behavior of m. natalensis and other small r ... | 2018 | 29572697 |
| distinct isotopic signatures reveal effect of ecoregion on small mammals of ghana. | species reside in dynamic environments, simultaneously experiencing variations in climatic conditions, habitat availability and quality, interspecific interactions, and anthropogenic pressures. we investigated variation in foraging ecology of the small mammal community between land-use classifications (i.e., protected national parks and unprotected lands abutting them) in mole national park (mnp) and digya national park (dnp), representing distinct ecoregions of ghana. in 5,064 trap nights, we s ... | 2018 | 29674787 |
| molecular detection of microorganisms associated with small mammals and their ectoparasites in mali. | small mammals are the natural reservoirs for many zoonotic pathogens. using molecular tools, we assessed the prevalence of bacteria and protozoans in small mammals and their ectoparasites in faladjè, bougouni, and bamoko, mali. a total of 130 small mammals belonging to 10 different species were captured, of which 74 (56.9%) were infested by ectoparasites, including laelaps echidnina, xenopsylla cheopis, amblyomma variegatum, rhipicephalus sanguineus sensu lato, and haemaphysalis spp. nymphs. dna ... | 2020 | 33146105 |
| widespread arenavirus occurrence and seroprevalence in small mammals, nigeria. | lassa fever, killing thousands of people annually, is the most reported viral zoonotic disease in nigeria. recently, different rodent species carrying diverse lineages of the lassa virus (lasv) in addition to a novel mobala-like genetic sequence were detected within the country. here, screening 906 small mammal specimens from 11 localities for igg antibodies and incorporating previous pcr detection data involving the same populations, we further describe arenavirus prevalence across nigeria in r ... | 2018 | 30005641 |
