Viremia and antibody titres in D2Y98P-infected mice.

Mice were ip. infected with 107 (A, C, E) or 104 (B, D, F) PFU of D2Y98P. At the indicated time points, five infected animals were bled and euthanized immediately. Viremia titres (A, B), specific anti-IgM (black circle) and IgG (open circle) titers (C, D), and PRNT50 (E, F) were determined for each individual serum. Results are representative of 2 independent experiments.
