| human retroviruses in amerindians of colombia: high prevalence of human t cell lymphotropic virus type ii infection among the tunebo indians. | the coexistence of infection with human t lymphotropic virus types i and ii (htlv-i and htlv-ii) has been demonstrated recently among the wayuu indians from the guajira region of colombia. to ascertain if other indian groups in colombia are similarly infected, we tested 1,250 sera, collected between 1990 and 1992 from 18 culturally distinct amerindian tribes living in widely separated regions, for igg antibodies against htlv-i/ii using enzyme-linked immunosorbent assay (elisa) and western blot. ... | 1993 | 8279632 |
| a survey of the human t-cell lymphotropic virus type i (htlv-i) in south-western colombia. | to evaluate altitude of birthplace and residence as factors associated with geographic clustering of htlv-i infection in colombia, we sampled a total of 670 current residents of the south pacific coastal lowland and of upland regions (cali and environs) of the valle and cauca provinces, located at an altitude of 3,100 ft. among the 255 lowland study subjects, 4.3% had antibody against htlv-i, compared to 0.9% of the 415 upland study subjects. a hypothesis emerging from this study is that the low ... | 1989 | 2777408 |
| antibody to htlv-i in indigenous inhabitants of the andes and amazon regions in colombia. | to explore the htlv-i-carrying groups among the indigenous inhabitants in south america, a sero-epidemiological study on htlv-i focusing on hinterland villages isolated from others in the andes and amazon regions was conducted. five (2.9%) out of 171 subjects showed positive for htlv-i antibody in the gelatin particle agglutination (pa) test. two out of 5 positives with high antibody titer (greater than or equal to x 1024) in the pa test also showed a positive immunofluorescence (if) test and an ... | 1990 | 1975804 |
