Genetic and Antigenic Diversity of Infectious Bronchitis Virus in South America.

Avian diseases - 1 Dec 2021

Abstract excerpt

Infectious bronchitis virus (IBV) is one of the economically most important diseases affecting the South American poultry industry. The extensive genomic heterogeneity of IBV is a consequence of high mutation rates and recombination events followed by selection. Nucleotide heterogeneity is much higher in the S1 coding region of the relevant spike protein; thus, the S1 sequence is widely used for the IBV genetic...
