One individual (a 56-year-old Baka Pygmy hunter) was found to be HTLV-3 infected; however, there was a low proviral load in blood cells. Complete sequence analysis of this virus (HTLV-3(Lobak18)) indicated a close relationship to human HTLV-3(Pyl43) and simian STLV-3(CTO604) strains. Plasma samples from Lobak18, the HTLV-3 infected individual, exhibited a peculiar "HTLV-2-like" pattern on Western blot analysis and were serologically untypeable by line immunoassay. These results were different from those for the 2 previously reported HTLV-3 strains, raising questions about serological confirmation of infection with such retroviruses. specialized CAMEROUN 052 199 4 561-564 2009 https://www.documentation.ird.fr/hor/PAR00003580 10.1086/596206 [F B010058426] https://www.documentation.ird.fr/hor/PAR00003580 https://www.documentation.ird.fr/intranet/publi/depot/2013-03-18/010058426.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-07-08 2025-11-04 PAR00003580 fre
