Abstract Between 2008 and 2010, 19 strains of infectious bronchitis virus (IBV) were isolated
from the vaccinated chicken flocks in Sichuan province, China. The S1 genes of the isolates …

Chimeric infectious bronchitis virus (IBV) genomes with cross-over sites in the S1 gene were
generated by co-infection with two distinct IBV strains. Recombinant viruses were collected …
