AB Simian immunodeficiency virus (SIV) infection in macaques is an
important animal model for human immunodeficiency virus infection in
humans. This study evaluated the temporal development of antibodies to
SIV in the parotid saliva of macaques inoculated with the virus and
compared these findings with the development of antibodies to SIV in the
animals' sera. Three animals (ages, 14, 18, and 18 years) were
inoculated with the macrophagetropic strain SIVmac239. Prior to
inoculation and at consecutive weekly intervals during a four-week
period following the initial virus inoculations, parotid saliva and
serum were collected from each animal. A fourth animal (age, 9 years)
served as a negative control, and the fifth and sixth animals (ages, 2
and 22 years) served as positive controls (6 and 18 months
postinoculation, respectively) with SIVmac239. Saliva and serum samples
were reacted against SIV antigen in Western blots (immunoblots) prepared
in the standard fashion to determine the presence of antibodies. The
reactions of these antigen-antibody complexes with biotinylated
anti-human immunoglobulin A (IgA), IgM, and IgG and biotinylated
anti-human secretory component (SC) determined the class of antibody
present or the presence of SC in the original parotid saliva or serum
samples. In infected animals, the IgM to SIV was detectable in serum and
saliva at 13 days, and antiviral IgA and IgG in serum and saliva were
detectable at 20 to 27 days postinoculation. The antibody to SC reacted
to saliva from only two animals at 20 and 27 days, and long-term
positive controls were positive for SC in saliva, indicating that either
secretory IgA or secretory IgM was present in these samples.(ABSTRACT
