| seroepidemiology of htlv-i/ii in argentina: an overview. | in this report, the results of seroepidemiologic studies of human t-lymphotropic virus type i (htlv-i) and type ii (htlv-ii) infections in different population groups in argentina have been compiled. the studies have shown a high prevalence of htlv-i/ii infection in blood donors in the provinces in the north of argentina (1.0% in jujuy, 0.7% in salta, and 0.6% in formosa) and a low prevalence in the provinces in the central region of the country (<or=0.1%). high rates of htlv-i (0.45%-2.78%) and ... | 2004 | 15076246 |
| prevalence of antibody to human t cell lymphotropic virus types 1/2 among aboriginal groups inhabiting northern argentina and the amazon region of peru. | we carried out a seroepidemiologic survey to define the prevalence of human t cell lymphotropic virus types 1/2 (htlv-1/2) infections among aboriginal populations from isolated regions of northern argentina and the amazon region of peru. antibodies against htlv were measured with agglutination tests and confirmed with by an immunofluorescence assay (ifa) and western blotting. five (6.94%) of 72 samples from the tobas indians in argentina were positive by the ifa; two samples were typed as htlv-1 ... | 1999 | 10348238 |
| 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 |
