Replication kinetics and antigenicity of the Chinese IDV strain. (A-D) Replication kinetics of the D/JY3002, D/JY3097, and rC/Vic/12 in different cell lines. MDCK (A), MDBK (B), ST (C) and HRT-18G (D) cell lines are inoculated with 0.01 or 0.1 MOI of the D/JY3002 or the rC/Vic/12. Aliquots of the tissue culture supernatant are taken at periodic intervals and virus titres are determined by TCID50 per mL in MDCK cells. (E) Viral titres of the D/JY3002, the rD/OK/11, the rD/OK660-HEF, and the rC/Vic/12. (F-H) The comparison of HI antibody titres of cattle serum samples against the D/JY3002, the rD/OK/11, and the rD/OK660-HEF.
