| african origin of human t-lymphotropic virus type 2 (htlv-2) supported by a potential new htlv-2d subtype in congolese bambuti efe pygmies. | we identified a potential new subtype within human t-cell lymphotropic virus type 2 (htlv-2), htlv-2d, present in members of an isolated efe bambuti pygmy tribe. two of 23 efe pygmies were htlv-2 seropositive, with htlv-2 western blot and enzyme-linked immunosorbent assay reactivities. from one of them the entire genome of the htlv-2 strain efe2 could be amplified and sequenced. in all gene regions analyzed, this strain was the most divergent htlv-2 strain, differing by 2.4% (tax/rex) to 10.7% ( ... | 1998 | 9557723 |
