Tissue distribution of FMDV in vaccinated steers.

<p>Numbers represent log₁₀ FMDV genome copy numbers (GCN)/mg of tissue or GCN/μl serum. <b>Bold</b> numbers indicate that samples were positive for both FMDV RNA (qRT-PCR) and virus isolation, (+) indicates that virus isolation was positive but FMDV RNA content was below the limit of detection, (-) indicates double negative samples. Limit of detection: 1.53 log₁₀ FMDV GCN/mg of tissue, <0.1 log₁₀ GCN/ μl serum (corresponding to an assay detection limit of 1.57 log₁₀ FMDV GCN/ml serum)</p><p>Tissue distribution of FMDV in vaccinated steers.
