| [epidemiology of leishmaniasis in french guiana in relation to the existence of a new species of echimyid rodent, proechimys cuvieri sp. n]. | the rediscovery and reexamination of the skull of the type of proechimys guyannensis (e. geoffroy; 1803) allows us to give more details about this species. it appears that a new sympatric species, p. cuvieri, has to be distinguished, which could have great implications for the leishmaniosis epidemiology in french guiana. | 1978 | 102437 |
| evidence of a sylvatic enzootic cycle of leishmania infantum in the state of amapá, brazil. | leishmania infantum was considered to be absent from amapá until 2017 when canine infection was detected. however, there is a lack of knowledge about which reservoir species are involved in transmission in this region. | 2019 | 31859944 |
| the role of pleistocene climate change in the genetic variability, distribution and demography of proechimys cuvieri and p. guyannensis (rodentia: echimyidae) in northeastern amazonia. | the spiny rats, genus proechimys, have the highest species richness within the echimyidae family, as well as species with high genetic variability. the genus distribution includes tropical south america and central america south to honduras. in this study, we evaluate the phylogeographic histories of proechimys guyannensis and p. cuvieri using cytochrome b, in a densely sampled area in northeastern amazon where both species are found in sympatry in different environments. for each species, bayes ... | 2018 | 30557386 |
| karyological analysis of proechimys cuvieri and proechimys guyannensis (rodentia, echimyidae) from central amazon. | the aim was to characterize the karyotype of rodents of the genus proechimys from three localities in the central brazilian amazon, in the search for new markers that might shed light on our understanding of the taxonomy and evolutionary history of this taxon. two karyotypes were found, viz., 2n = 28, fn = 46 in individuals from the nrsp (cuieiras river) and reman (manaus), and 2n = 46, fn = 50 in individuals from the balbina hydroelectric plant. while individuals with the karyotype with 2n = 28 ... | 2012 | 22481879 |
