Genetic evidence for two founding populations of the Americas
Reconstructing Native American population history
Mitochondrial Population Genomics Supports a Single Pre-Clovis Origin with a Coastal Route for the Peopling of the Americas
Genetic Variation and Population Structure in Native Americans
We examined genetic diversity and population structure in the American landmass using 678 autosomal microsatellite markers genotyped in 422 individuals representing 24 Native American populations sampled from North, Central, and South America. These data were analyzed jointly with similar data available in 54 other indigenous populations worldwide, including an additional five Native American groups. The Native American populations have lower gen…
Human T-cell lymphotropic virus type II in Guaraní Indians, Southern Brazil
Human T-cell lymphotropic virus type II (HTLV-II) is found in many New World Indian groups on the American continent. In Brazil, HTLV-II has been found among urban residents and Indians in the Amazon region, in the North. Guaraní Indians in the South of Brazil were studied for HTLV-I/II infection. Among 52 individuals, three (5.76%) showed positive anti-HTLV-II antibodies (enzyme-linked immunosorbent assay and Western blot). This preliminary repo…
Demographic and Genetic Structures of Two Partially Isolated Communities of Santa Catarina Island, Southern Brazil
The objectives of this study were to analyze the population structure and genetic variability of two communities, Costa da Lagoa (CLG) and São João do Rio Vermelho (SJRV), located on Santa Catarina Island in southern Brazil. The two populations descend from Azores Archipelago immigrants (Portuguese), with a minor contribution of sub-Saharan Africans and Amerindians. To estimate the relative contribution of the different ethnic groups to the curre…
Perfil de auto-anticorpos em índios das tribos Kaingang e Guarani do Sul do Brasil
This study investigated the autoantibody profile of 241 blood samples from 176 Kaingang and 65 Guarani Indians from three populations living on the Rio das Cobras and Ivaí reservations, in the state of Paraná, in southern Brazil. The presence of antimitochondrial, anti-smooth muscle, antinuclear, anti-parietal cell, and anti-liver-kidney microsome antibodies was determined by indirect immunofluorescence. These results were compared with samples f…
