FMDV load in lymphoid tissues. Each graph indicates the FMDV RNA molecules (grey bars) or PFU (black bars) per mg of tissue as indicated: tonsil, spleen thymus inguinal lymph node (ING LN), pre-scapular, lymph node (PRES LN), mesenteric lymph node (MES LN), mediastinal lymph node (MED LN) and retro-pharyngeal lymph node (RTF LN). The dotted line indicates the detection limit for FMDV RNA (103 FMDV RNA molecules) and the black line indicates the detection limit of the FMDV titration (5 PFU/mg of tissue). Each bar corresponds to one animal.
