Mhf blood loads in passively immunized and control cats after Mhf infection. Mhf blood loads (y-axis, as log copies/mL of blood) of individual cats in group A (A) and B (B) and mean (+SD) Mhf blood loads in group A and B (C) are shown during the 100 days pi. Because of the logarithmic scale, only the positive SD is shown in (C). All cats were subcutaneously inoculated with Mhf at day 0. Significant differences between groups are indicated with asterisks (p_MWU < 0.05). Cat JHW3 in group B stayed PCR-negative throughout the 100-day follow-up period but turned PCR-positive at day 154 pi (not shown).
