| seroepidemiological and molecular studies of human t cell lymphotropic virus type ii, subtype b, in isolated groups of mataco and toba indians of northern argentina. | we studied plasma samples from 2082 mataco indians living in 22 different communities in the western part of formosa province, northern argentina. samples were screened for htlv-i/ii antibodies by particle agglutination assay. all positive or borderline samples were then tested by an immunofluorescence assay (ifa) on c19 htlv-ii-producing cells. western blot was used for confirmation of all ifa-positive plasma samples. the crude htlv-ii seroprevalence was 3.0% (62 of 2051), and 0.9% (5 of 588) i ... | 1999 | 10195750 |
| [absence of htlv-i/ii virus circulation in blood donors from the provinces of santa fe and santiago del estero]. | in the present study, we evaluated the seroprevalence of htlv-i/ii infection among the blood donors in santa fe and santiago del estero provinces. a total of 1327 serum samples from blood donors from rafaela blood bank of santa fe province and 3382 serum samples from blood donors from dr edgar bouzon blood bank of santiago del estero province were studied. the antibody screening was done by particle agglutination assay (pa) (serodia, fujirebio inc., tokyo, japan) or by enzyme immuno assay (eia) ... | 2002 | 12180256 |
