HIV type 1 drug resistance in adults receiving highly active antiretroviral therapy in Abidjan, Côte d'Ivoire.

abstract：:HIV antigens were detected by immunoelectron microscopy at the surface of human and simian T4 lymphocytes that had been infected in vitro. HIV antigens were detected at the surface of cells exhibiting viral particles but also at the surface of cells before the release of virions. The latter cells may be considered imm...
