Infectious bronchitis virus (IBV), a major pathogen of commercial poultry flocks, circulates in the form of several serotypes/genotypes. Only a few amino-acid changes in the S1 subunit of wild-type IBVS proteins may result in mutants unaffected by current vaccines. Partial S1 gene sequences of 3 IBV isolates of the Moroccan Italy 02 genotype from vaccinated… CONTINUE READING
