    Abstract:
    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.
