“…In our study, most infected individuals whose samples were in the blood bank were Guyanese Africans; only one Amerindian had HTLV-1 infection. Many studies of the seroprevalence of HTLV-1 in South America have shown that the prevalence of HTLV-1 is much higher among peoples of African origin than among Amerindians (15). It has been suggested that the Amerindian populations were infected through contact with slaves of African origin (13,49).…”

The prevalence of human T-cell lymphotropic virus type 1 (HTLV-1) and HTLV-2 in blood donors in Guyana has never been estimated. We evaluated the prevalence of these viruses in blood donors by enzyme-linked immunosorbent assay and Western blotting and showed a prevalence of HTLV-1 of 1.3%; no HTLV-2 was detected. Female donors had a much higher HTLV-1 seroprevalence (3.6%) than male donors (0.7%). HTLV-1-seropositive donors tended to be slightly older than the average age for the total pool of donors. We also investigated the phylogenetic and molecular characteristics of HTLV-1 strains in Guyana and compared them with those identified in Suriname and French Guiana. Analysis of portions of the env and long terminal repeat nucleotide sequences showed that all the strains in Guyana and Suriname, like those in French Guiana, belonged to the transcontinental group of cosmopolitan subtype A. The similarities were greater between strains from Suriname and Guyana than between strains from Suriname and Guyana and those from French Guiana. Nevertheless, our results confirm that the HTLV-1 strains in all three countries have a common African origin.

“…HTLV-I is thus very rare in Amerindians, in contrast to the situation with HTLV-II. HTLV-I seroprevalence rates ranging from 1 to 10% are found in the adult populations of some groups in Argentina, Brazil, Colombia, Peru, and several Caribbean countries, including Guadeloupe, Jamaica, Martinique, and Trinidad and Tobago (Gessain, 1996;Gotuzzo et al, 2000).…”

We review here the epidemiological studies performed by our group on human retrovirus HTLV-I and HTLV-II infections and the associated diseases in French Guiana since 1984. French Guiana is an overseas French administrative district located between Key words Retroviridae; HTLV-I; HTLV-II; Genetic Variability; T-cell Leukemia Resumo Os autores apresentam uma revisão dos estudos epidemiológicos realizados pelo seu grupo de pesquisa sobre a infecção pelos vírus T-linfotrópicos humanos tipo I (HTLV-I) e tipo II (HTLV-II) e doenças associadas na Guiana Francesa, desde 1984.

“…La asociación entre HTLV-1 y la estrongiloidiasis todavía no está bien dilucidada, siendo imposible definir con precisión cuál es el papel de cada uno de los agentes sobre la patogenia y las complicaciones clínicas del otro 58 . Un estudio publicado por Matutes indica que individuos portadores de HTLV-1 presentan una mayor predisposición al desarrollo de infecciones oportunistas y sus formas graves, entre ellas la producida por S. stercoralis; ese fenómeno ha sido atribuido al compromiso de la inmunidad celular 59 .…”
