molecular analysis of human t cell lymphotropic virus type 1 and 2 (htlv-1/2) seroindeterminate blood donors from northeast iran: evidence of proviral tax, env, and gag sequences. | human t cell lymphotropic virus type 1 and 2 (htlv-1/2) western blot indeterminate results are a problem for blood banks in endemic areas. to determine the prevalence of htlv-1/2 infection among indeterminate donors, we analyzed 130 cases from mashhad, an htlv-1/2 endemic area in northeast iran. the most frequent western blot bands were gd21 alone (37.2%) followed by rgp46-2 alone (32.1%). we further tested 40 available dna samples of these cases by pcr for viral sequences, tax, gag, and pol, an ... | 2010 | 20929385 |
