Abstract
Infectious bronchitis virus (IBV) causes tremendous economic losses to the poultry industry. Here, we report the complete genome analysis results for a new natural recombination nephropathogenic IBV strain named SAIBK, which was isolated in the Sichuan province of China in 2005.

Infectious bronchitis virus (IBV) causes tremendous economic losses to the poultry industry
Phylogenetic analysis of the complete genome results indicated that the SAIBK strain clusters into the same branch as the IBV YN strain
The S1 subunit of the IBV genome is the major determinant of serotype [10,11,12,13], and S1 analysis indicated that the SAIBK strain has a 4/91-like serotype
Summary
Infectious bronchitis virus (IBV) causes tremendous economic losses to the poultry industry. Many epidemiological analysis reports have suggested that nephropathogenic IBVs have become increasingly prevalent [3,4,5,6] in China. The complete genome sequence of an isolate named SAIBK was analyzed and recombination was detected between SAIBK and some previously reported IBVs. A rapid amplification of cDNA ends (RACE) kit (TaKaRa, Japan) was used to obtain the 5= and 3= ends of the genome.
