Although direct feline immunodeficiency virus (FIV) proviral DNA inoculation has been shown to be infectious in cats, long-term studies to assess the pathogenic nature of DNA inoculation are lacking. We have recently reported that direct feline leukemia virus (FeLV) DNA inoculation resulted in infection and the development of FeLV-related disease end points with similar temporal expression and virulence to that of cats infected with whole virus. We show in this study that pFIV-PPR DNA inoculation resulted in infection of cats and the development of FIV-related immunologic and neurologic abnormalities. Infected cats demonstrated progressive loss of CD4+ lymphocytes resulting in decreased CD4: CD8 ratios. Neurologic dysfunction was demonstrated by increased bilateral frontal lobe slow-wave activity. Prolongation of the visual evoked potential peak latency onset response pattern also supported a similar progression of abnormal cortical response. Furthermore, histopathologic examination revealed lesions attributed to FIV infection in lymph node, thymus, brain, and lung. Finally, nested polymerase chain reaction detected FIV provirus in brain, bone marrow, mesenteric lymph node, thymus, spleen, tonsil, and liver. These results confirm that FIV DNA inoculation is an efficient model for study of the pathogenic nature of molecular clones in vivo and offers the opportunity to measure temporal genomic stability of a homogeneous challenge material.
