Infectious bronchitis virus (IBV) of GI-19 (QX), GI-7 (TW), GI-13 (4/91) and GI-1 (Mass) lineages have been frequently detected in China in recent years. Here, An IBV strain, referred as GD17/04, was isolated from the dead yellow feather chicken vaccinated with H52 and 4/91 vaccines, whose genome sequence was obtained through high-throughput sequencing. Then it has been confirmed by the RDP and SimPlot analysis that GD17/04 is a recombinant strain deriving from YX10, 4/91, TW 2575/98 and H52 strains. Therein S1 gene of GD17/04 consists of sequences of TW2575/98 and 4/91, the former for the region of 20,371 to 21,072 nt and 21,847 to 21,975 nt, the latter for the sandwiched region of 21,073 to 21,846 nt. Moreover, as a nephropathogenic variant which caused high morbidity of 100 % and mortality of 60 %, unlike most other IBV strains, GD17/04 can cause obvious cell lesion in primary CEK cell, and even in DF-1 cells, without the process of continuous passage. As the few IBV strain can infect avian passage cell line, GD17/04 provides a material basis for further study of the interaction mechanism between IBV and avian host. Collectively, the findings highlight the significance that biological characteristics of novel strain should be studied, in addition to constant epidemiologic and molecular surveillance for IBV.
