[http://www.aidsonline.com/]0269-93701473-5571http://hdl.handle.net/2263/3532We compared the genetic diversity of the Brazilian human T-cell lymphotropic virus type 1 isolates with those found in KwaZulu–Natal (KZN), South Africa, and with the genetic background of the hosts. The seroprevalence rate in KZN was 1.7%. All sequences belonged to the A subgroup. The presence of South African sequences in two different clusters from Brazil, and the finding of the bA-globin haplotype in infected hosts are consistent with the transmission of this virus from Southern Africa to Brazil.256674 bytesapplication/pdfenLippincott Williams & Wilkins.
