| htlv-1 infection in blood donors from the western brazilian amazon region: seroprevalence and molecular study of viral isolates. | to determine the seroprevalence of htlv-1 in brazil, and to review the virus molecular epidemiology in this amazon population (rio branco-acre), 219 blood donors were screened for htlv-1. only one case of infection (0.46% seroprevalence) was detected during july 2004 screening at the acre hospital foundation (fundacre). neighbor-joining and maximum likelihood phylogenetic analyses of two (n = 2) complete ltr region sequences were performed with the paup* software. since the htlv-1 envelope surfa ... | 2008 | 18814249 |
| [seroprevalence of human t cell lymphotropic virus infection and associated factors of risk in blood donors of rio branco city, ac, brazil (1998-2001)]. | between december 1998 and march 2001, for each htlv-i/ii seropositive blood donor (elisa, abbott), two htlv-i/ii seronegative blood donors were also chosen. the blood samples were re-tested by elisa (murex), and those seropositives were also tested by western blot and pcr. of the 11, 121 blood samples, 73 (0.66%) were positives (abbott), but only 12 (0.11%) remained positives (murex), whereas the 146 seronegatives were confirmed, even though the concordance index between these two elisa tests wa ... | 2003 | 15049106 |
