Genomic characterization of some infectious laryngotracheitis virus (ILTV) field isolates from vaccinated chicken farms reveals evidence of vaccine-related genetic drift.

Abstract excerpt

ILTV remains a highly contagious respiratory pathogen causing substantial economic losses on the global poultry industry. Despite the long-term implementation of routine vaccination programs, recurrent outbreaks in vaccinated flocks suggest that the virus's genomic flexibility, driven by both genetic drift and inter-strain recombination, may be undermining traditional control measures. This study aimed to...
