Abstract Background In vivo studies on HIV-I pathogenesis and testing of antiviral strategies have been hampered by the lack of an immunocompetent small animal model that is highly susceptible to HIV-I infection. Since native rodents are non-permissive we developed transgenic rats that selectively express the HIV-I receptor complex hCD4 and hCCR5 on relevant target cells. These animals display a transient low-level
