Figure 1.
Time course of infectivity titer in representative BSE-infected donor and recipient sheep, as determined by mouse bioassay. Infectivity titers (ID50/mL WB), as determined by end point titration in TgBov mice, were plotted according to percentage survival period (% SP), for 3 BSE-infected donor sheep N236, N218, and N245 (colored blue, red and green, respectively) (A); and 3 BSE-infected recipients P480, M246, and M490 (colored pink, orange and black, respectively) (B). Error bars represent 95% confidence intervals.
