Figure 4. Absence of neutralising antibodies in early FIV infection – Group 1.

Figure 4

Sequential plasmas from group 1 (822, 823 and 824) animals collected at 0,3,6,10,12,15,18 and 21 weeks post-infection were diluted 1∶100 and assayed for the ability to neutralise HIV(FIV) pseudotypes bearing the B32 Env. Also shown are pooled uninfected (−ve) plasma and post-mortem plasma from A613 (+ve). Neutralisation data are shown in comparison with total proviral loads for each cat as estimated using either gag or env–specific real-time PCR. All estimates of proviral load and luciferase activity are displayed as mean (n = 3) +/− SE.
