The antigenicity of ten IBVs, including seven field strains and commonly used vaccine strains, were assayed with a viral cross-neutralization assay in chicken embryonated kidney cells (CEK). To determine the antigenic relatedness between the field IBV isolates and the vaccine viral strains, double-direction viral cross-neutralization (VN) tests were performed in chicken embryo kidney (CEK) cells using constant viral titers and diluted serum. The tested strains came from six different genotypes and included seven IBV field isolates (Sczy3, cK/CH/SCDY/141030, cK/CH/SCLS/140104, cK/CH/CQKX/ 150203, cK/CH/SCYB/140913, cK/CH/SCMY/10I, cK/CH/SCYB/141102) and the three most commonly used vaccine viral strains (H120, M41, and 4/91). Ten IBVs, including seven field strains from different genotype backgrounds and three commonly used vaccine strains (H120, 4/91, and M41), were analyzed and grouped into four serotypes: Massachusetts (Mass hereafter), 793B, Sczy3, and SCYB.	./cache/cord-263476-ju7xqwa7.txt	./txt/cord-263476-ju7xqwa7.txt
