Evidence for dual infection of rabbits with the human retroviruses HTLV-I and HIV-1.
Rabbits experimentally infected with HTLV-I and HIV-1 produced antibody to various viral proteins, and viral DNA could be detected by gene amplification using the polymerase chain reaction. HTLV-I genes were detected in cell lines derived from infected rabbits, and in some cases, both HIV-1 and HTLV-I DNA sequences were demonstrated in peripheral blood cells taken from rabbits one year after experimental infection. The polymerase chain reaction procedure was used to demonstrate the presence of HTLV-I gag, env and tax genes and HIV-1 gag and env genes. The amplified fragments were identified by size and by hybridization to specific probes. The ability of rabbits to support simultaneous infection with HTLV-I and HIV-1 will allow in vivo studies of the possible synergistic effects of these important human pathogens.
