FIG. 1.

Quantification of proviral load and CD4/CD8 ratio in FIV-infected cats during the acute phase of infection. Three cats were inoculated intraperitoneally with either GL8₄₁₄ (○), PET_F14 (▿), or mock infected with PBS (□). (A) Proviral DNA load in PBMCs was estimated by real-time PCR (control cats were consistently negative and thus are not shown). Each point represents the mean proviral load of the three cats in the group (± standard error). (B) The CD4/CD8 ratio was estimated by flow cytometry. Results represent the mean CD4/CD8 ratio of the three study groups (± standard error).
