Overview

AE strains genetically similar to vaccine may drive poultry outbreaks; leaves open vaccine breakdown versus persistence mechanisms.

Structured PICO

Population

Breeder and commercial chickens in South Korea, including young chickens <4 weeks old and unvaccinated 79-day-old chickens showing neurological signs (ataxia, paralysis).

Intervention

Phylogenetic analysis of viral protein 2 genes and embryo-inoculation test via yolk sac of avian encephalomyelitis (AE) viruses.

Outcome

Genetic characterization and embryo-adaptation of AE field viruses.

Avian encephalomyelitis outbreaks in South Korea were caused by strains genetically similar to the vaccine strain, suggesting vaccine breakdown or persistence in the chicken population.
