Most molecular trees of trypanosomatids are based on point mutations within DNA sequences. In contrast, there are very few evolutionary studies considering DNA (re) arrangement as genetic characters. Waiting for the completion of the various parasite genome projects, first information may already be obtained from chromosome size-polymorphism, using the(More)
Gene expression is known to vary significantly during the Leishmania life-cycle. Its monitoring might allow identification of molecular changes associated with the infective stages (metacyclics and amastigotes) and contribute to the understanding of the complex host-parasite relationships. So far, very few studies have been done on Leishmania (Viannia)(More)
Intradermal infection of rabbits with Treponema pallidum imitiates rapid and active cellular response at the site of injection. During the first 2 weeks following infection, there is a marked increase in the numbers of organisms at the site of infection. Systemic dissemination of treponemes occurs during the early stage of infection, presumably before the(More)
[1] Three‐dimensional seismic data are used to assess the control of halokinetic structures on the distribution of blocks in a mass transport deposit in the Espírito Santo Basin, southeast Brazil. In contrast to what is commonly observed over growing salt structures, the thickness of the MTD‐A1 is larger on top of a northwest trending salt ridge. Emphasis(More)
Submarine mass-transport deposits (MTDs) frequently include blocks of strata with variable deformation styles. In this paper, a 3D seismic volume from SE Brazil is compared with outcrop information from SE Crete to investigate multi-scale deformation patterns within mass-transport blocks. Block morphology relates closely to the orientation of internal(More)
High-quality 3D seismic data are used to interpret the styles and scale-relationships of architectural elements on the continental slope of Espírito Santo (SE Brazil). Sand-prone architectural elements identified in this work include: a) axial canyons incising a salt-withdrawal basin (Unit 1), b) turbidite lobes intercalated with heterogeneous(More)
Leishmania (Viannia) braziliensis and L. (V.) peruviana are two parasite species characterized by a very different pathogenicity in humans despite a high genetic similarity. We hypothesized previously that L. (V.) peruviana would descend from L. (V.) braziliensis and would have acquired its 'peruviana' character during the southward colonization and(More)
