| htlv-2 horizontal and vertical transmission in a family from a brazilian urban area: seroepidemiological, clinical and molecular study. | human t cell lymphotropic virus type 2 (htlv-2) has been shown to be endemic in brazilian indians and among intravenous drug users in urban areas, but transmission of this infection seems to be infrequent in the general population living in urban areas in brazil. six persons in three generations of a brazilian family were evaluated to assess htlv-2 transmission and its molecular features in the positive cases. the index was detected during screening (htlv eia) of donated blood in fundação hemomi ... | 2005 | 15989456 |
