 AB    The viral loads in adult and newborn cats have been compared following
       injection with feline CD4+ FeL-039 line cells acutely infected with
       feline immunodeficiency virus (FIV). The level of virus genome in
       peripheral blood mononuclear cells (PBMC) increased progressively
       despite seroconversion in the newborn cats, whereas the virus genome was
       apparently cleared after seroconversion in the adult cats.
       Immunohistochemical staining of thymus of the FIV-infected newborn cats
       showed clusters of viral antigen-positive cells. These results indicate
       that FIV infection of the newborn cat results in higher virus loads than
       infection of the adult cat. We discuss these findings in relation to FIV
       as a model system for studies of the infection of neonates with an
       immunosuppressive retrovirus.
