Mean CD4+:CD8+ T-cell ratio of cats following i.c.v. inoculation with cell-free FIV (FIV-I.C.V., n = 6), i.p. inoculation with cell-free FIV (FIV-I.P., n = 3) or i.c.v. inoculation with FIV infected ChP macrophages (ChP-Mac, n = 4). The ratio after inoculation was normalized to the preinoculation CD4+:CD8+ ratio. Cell-free FIV infection resulted in a progressive drop of the CD4+:CD8+ ratio in all cats regardless of the inoculation route (Ps < .001). Cats inoculated with FIV infected ChP-Mac showed a mild but significant drop in the CD4+:CD8+ ratio to 67% to 78% of the preinoculation values (P = .0003). Values are mean ± SEM.
