Infectious center frequencies in FV-Katushka-mTagBFP in BALB/c-based IL-10-eGFP reporter mice. Highly susceptible IL-10-eGFP mice of BALB/c background were infected with 500 SFFU of FV-Katushka-mTagBFP and viral loads in the bone marrow, lymph nodes and spleen on days 2, 4, 7, 10, 14 and 28 (A) and 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 7 (day 14), 8 (day 7) or 10 (day 2, 4, 10 28) mice per group were obtained in 1–2 independent experiments per time point
