Table 1 RT-PCR of the influenza A virus matrix gene-fragment results and virus titers in swabs and organs of H5N8-infected wild Common buzzards (Buteo buteo). *Cycle threshold (Ct) value, cut-off value is 40; ** all titers are given in TCID50 log 10; # this value is likely an outlier; n, negative (< 0.5 for virus titers); np, not present.
