Note: Data (mean ± SD, n = 4) in the table is the percentage of MDCK cytopathy caused by different H5N1 AIV dilution which is the value of cytopathy cells/total cells; P < 0.01. TCID50 was obtained from the data and PFU was converted from TCID50 with formula logTCID50 = log pfu + 0.67. The pfu of the two samples was as the follows: pfu (a) = 10-4.17/ml, pfu (b) = 10-3.87/ml
