| htlv type i and htlv type ii infection among indians and natives from argentina. | endemic foci for htlv-ii infection have been identified in several amerindian populations. to determine htlv-i and/or htlv-ii infection among amerindians living in argentina we studied 454 sera or plasmas from indians and natives from different areas of our country. all samples were tested by the particle agglutination technique, and positive reactions were confirmed by the immunofluorescence assay (ifa). ifa titration was used to differentiate htlv-i and htlv-ii antibodies. twenty-three of 222 ... | 1994 | 7888211 |
| a cluster of human t-cell lymphotropic virus type i-associated myelopathy/tropical spastic paraparesis in jujuy, argentina. | compared with other regions in argentina, greater human t-cell lymphotropic virus type i (htlv-i) seroprevalence has been reported in jujuy province, where it reaches 2.32% in the general population, so that a search for htlv-i-associated myelopathy/tropical spastic paraparesis (ham/tsp) cases deserved to be carried out. accordingly, a clinically diagnosed and serologically confirmed cluster of cases in 1 man and 10 women, including 2 sisters, is described here. most patients (9/11) were born in ... | 2003 | 12640204 |
| 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 |
| high prevalence of htlv-i and htlv-ii among blood donors in argentina: a south american health concern. | after an htlv-i endemic area was discovered in jujuy, a northwestern province in argentina, to detect other possible foci of htlv-i/ii we started in 1997 a multicentric study to estimate the seroprevalence of htlv-i/ii including blood banks from different regions of the country. out of 123,233 samples from nine different provinces, 68 proved seropositive with a final prevalence of 0.05% (95% ci = 0.0432-0.0704%). the seroprevalence ranged from 0.03 to 0.16% depending on the geographic location. ... | 2005 | 15665638 |
