Infectious center frequencies in FV-Katushka-mTagBFP in BALB/c mice. Highly susceptible BALB/c mice were infected with 500 SFFU of FV-Katushka-mTagBFP, and viral loads in the bone marrow, lymph nodes and spleen on days 4, 7, 10, 14 and 21 (A) and the spleen weights (B) were analyzed. Each dot indicates an individual mouse, bars indicate the median (A) or mean values (B). The dotted line indicates the detection limit. Data from 6 (days 4, 7, 10, 21) or 9 (day 14) mice per group were obtained in 1–3 independent experiments per time point
