Abstract excerpt
The first 440 nucleotides of the S1 part of the spike protein (S) gene of three nephropathogenic infection bronchitis virus (IBV) strains (BJ1, BJ2 and BJ3), isolated from three rural chicken farms of Beijing with outbreaks of avian infectious bronchitis, were sequenced after reverse transcriptasenested polymerase chain reaction amplification. The sequence data were analyzed and compared with the standard IBV...
