| 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 |
| body size variability and water balance: a comparison between mainland and island populations of mastomys huberti (rodentia: muridae) in senegal. | generally rodents are found to be larger on islands than on the mainland. however, there are some exceptions to this rule, and the aim of this paper is to examine one of them. on the mainland of senegal, mastomys huberti occupies humid habitats. however, it occurs also on dry and sandy islands (saloum delta), where its representatives are dwarf. since water availability appeared to be the limiting factor in these islands when compared to the mainland, we studied water turnover characteristics in ... | 1995 | 7729506 |
| a longitudinal survey of borrelia crocidurae prevalence in rodents and insectivores in senegal. | we report results of a longitudinal survey designed to determine the importance and the dynamics of borrelia crocidurae, the spirochete responsible for tick-borne relapsing fever in west africa in rodents and insectivores in a rural area of northern senegal. a total of 954 animals were caught during bimonthly capture sessions over a two-year period. positive thick blood smears were recorded in 17.6% of the 740 rodents and 7.3% of the 55 musk shrews tested. variations of prevalence were analyzed ... | 1994 | 8116808 |
| susceptibility of rodents to infection with schistosoma mansoni in richard-toll (senegal). | the susceptibility of arvicanthis niloticus, mastomys huberti, mastomys erythroleucus and mus musculus was studied to assess the capacity of these rodents to transmit schistosoma mansoni. the susceptibility was determined by the percentage of adult schistosomes recovered, the number of eggs per gramme of faeces, the viability of these eggs and the capacity of the rodents to maintain the life cycle of schistosoma mansoni. the percentages of adult worms recovered were respectively 18%, 11.5%, 8.4% ... | 1996 | 9033908 |
| comparison of human and murine isolates of schistosoma mansoni from richard-toll, senegal, by isoelectric focusing. | studies on human and murine isolates of schistosoma mansoni, from richard-toll, senegal, were carried out by isoelectric focusing in polyacrylamide gels. seven enzyme systems; lactate dehydrogenase (ldh), malate dehydrogenase (mdh), glucose-6-phosphate dehydrogenase (g6pd), acid phosphatase (acp), hexokinase (hk), glucose phosphate isomerase (gpi), and phosphoglucomutase (pgm), were used to compare the two isolates. all systems tested, apart from ldh, were found to be polymorphic for both isolat ... | 1997 | 9192707 |
| permissiveness of two african wild rodents, mastomys huberti and arvicanthis niloticus, to schistosoma intercalatum: epidemiological consequences. | the compatibility between schistosoma intercalatum (cameroon) and two wild rodents commonly found in africa. mastomys huberti (the multimammate mouse) and arvicanthis niloticus (the nile rat) was studied to determine their biological capacities to act as hosts for s. intercalatum. in both rodent species the general mean worm recovery was high (33 +/- 0.1% in m. huberti and 33.8 +/- 0.1% in a. niloticus) and worm mortality was very low from 6 to 20 weeks postinfection; parasite maturity was reach ... | 1997 | 9211508 |
| subulura saloumensis n. sp. (nematoda, subuluroidea) from four species of rodents in senegal. | a new species of the genus subulura is described from 4 new rodent hosts: arvicanthis niloticus, mastomys erythroleucus, mastomys huberti, and tatera gambiana. subulura saloumensis n. sp. differs from the congeneric species by the morphology of its head. the absence of buccal lobes, the length of right and left spicules, the absence of caudal alae, and the existence of a caudal papillae with a sensorial bristle. the latter, which we observe for the first time in specimens gathered from m. hubert ... | 1998 | 9645859 |
| the potential role of rodents in the enzootic cycle of rift valley fever virus in senegal. | wild rodents (214) of fourteen species were trapped at seven sites in senegal. arvicanthis niloticus and mastomys erythroleucus were among the most frequently collected species (77.2% of total capture). all rodents were examined for the presence of anti-rift valley fever virus (rvfv) antibody; the prevalence over all sampled species was 3.8%, varying widely with respect to species and location. four of 14 species of rodents were found to have anti-rvfv antibodies: rattus rattus (one positive of ... | 2000 | 10817634 |
| rodents as reservoir hosts in the transmission of schistosoma mansoni in richard-toll, senegal, west africa. | more than 2000 animals belonging to six different rodent species and one insectivore species were examined for infection with schistosomes in the region of richard-toll, senegal. two murid rodents, arvicanthis niloticus and mastomys huberti, were found infected with schistosoma mansoni. prevalences were about 5% for both rodent species with a mean worm burden of about 20 worms per host. the sex-ratios of s. mansoni worms were always biased towards males. prevalences and worm burdens, although si ... | 2000 | 10881283 |
| ultrastructure of the spermatozoon of raillietina (raillietina) baeri (cyclophyllidea, davaineidae) an intestinal parasite of the multimammate rat, mastomys huberti (rodentia, muridae). | the mature raillietina (raillietina) baeri spermatozoon exhibits an apical cone of electron-dense material about 2.5 microm long and 0.5 microm wide and two helicoidal crest-like bodies roughly 100-125 nm thick. the latter are of different lengths, spiralized and stand in an angle of about 50 degrees with the spermatozoon axis. the axoneme is of the 9 + "1" pattern and does not reach the posterior extremity of the gamete. the nucleus is an electron-dense cord coiled in a spiral around the axonem ... | 2005 | 15988603 |
| phylogeography of a sahelian rodent species mastomys huberti: a plio-pleistocene story of emergence and colonization of humid habitats. | the multimammate rat mastomys huberti is a sahelian species restricted to west africa. throughout its distribution area, the species is associated with humid habitats, flood plains and ponds, which make its current distribution highly fragmented. knowing that humid and dry climatic phases regularly alternated along the quaternary in west africa, it can be postulated that the evolutionary history of the species and its genetic variation largely reflect these climatic oscillations. we used mitocho ... | 2008 | 18261047 |
| borrelia infection in small mammals in west africa and its relationship with tick occurrence inside burrows. | tick-borne relapsing fever (tbrf) is a zoonotic disease caused by several borrelia species transmitted to humans by ornithodoros tick vectors. in west africa, borrelia crocidurae is a common cause of disease in many rural populations. small mammals act as reservoirs of infection. we report here the results of surveys that investigated the occurrence of b. crocidurae infection in rodents and insectivores from eight countries of west and central africa. animals were identified at the species level ... | 2015 | 26327444 |
| pterygodermatites (mesopectines) senegalensis n. sp. (nematoda, rictulariidae), a parasite of mastomys huberti (rodentia, muridae) in senegal. | pterygodermatites (mesopectines) senegalensis n. sp. (nematoda: rictulariidae) is described from mastomys huberti in senegal. it differs from other species of the subgenus by the morphology of the head, which exhibits 4 simple cephalic papillae and a nearly axial buccal opening, the length of the spicules, the number of precloacal cuticular formations, and the absence of cephalic apophyses. | 2000 | 11191909 |
| multihost transmission of schistosoma mansoni in senegal, 2015-2018. | in west africa, schistosoma spp. are capable of infecting multiple definitive hosts, a lifecycle feature that may complicate schistosomiasis control. we characterized the evolutionary relationships among multiple schistosoma mansoni isolates collected from snails (intermediate hosts), humans (definitive hosts), and rodents (definitive hosts) in senegal. on a local scale, diagnosis of s. mansoni infection ranged 3.8%-44.8% in school-aged children, 1.7%-52.6% in mastomys huberti mice, and 1.8%-7.1 ... | 2020 | 32441625 |
| rodents of senegal and their role as intermediate hosts of hydatigera spp. (cestoda: taeniidae). | hydatigera (cestoda: taeniidae) is a recently resurrected genus including species seldom investigated in sub-saharan africa. we surveyed wild small mammal populations in the areas of richard toll and lake guiers, senegal, with the objective to evaluate their potential role as intermediate hosts of larval taeniid stages (i.e. metacestodes). based on genetic sequences of a segment of the mitochondrial dna gene cytochrome c oxidase subunit 1 (coi), we identified hydatigera parva metacestodes in 19 ... | 2019 | 30152308 |
| mini-flotac as an alternative, non-invasive diagnostic tool for schistosoma mansoni and other trematode infections in wildlife reservoirs. | schistosomiasis and food-borne trematodiases are not only of major public health concern, but can also have profound implications for livestock production and wildlife conservation. the zoonotic, multi-host nature of many digenean trematodes is a significant challenge for disease control programmes in endemic areas. however, our understanding of the epidemiological role that animal reservoirs, particularly wild hosts, may play in the transmission of zoonotic trematodiases suffers a dearth of inf ... | 2019 | 31522684 |
| plagiorchis sp. in small mammals of senegal and the potential emergence of a zoonotic trematodiasis. | trematodes of the genus plagiorchis have a wide geographical distribution and can exploit a variety of hosts. the occurrence and zoonotic potential of plagiorchis spp. have been characterised across several countries in asia; in contrast, information on plagiorchis parasites in africa remains anecdotal. we isolated a previously undescribed plagiorchis species from the biliary tract and small intestine of 201 out of 427 small mammals collected in the region of lake guiers, senegal, with local pre ... | 2019 | 30834193 |
