Identifies early duodenal and pancreatic entry points for potential intervention in chicks; leaves open validation in natural outbreaks and vaccine strategies.
Avian encephalomyelitis virus orally infects chicks by first invading the duodenum and pancreas before spreading to other organs and the CNS via viremia.
T. Miyamae (1983) studied Avian encephalomyelitis virus infection. Oral infection with avian encephalomyelitis virus was evaluated on Invasion sites of avian encephalomyelitis virus in internal organs. Oral infection with avian encephalomyelitis virus in chicks began in the duodenum, followed by viremia, rapid infection of the pancreas, and subsequent spread to the central nervous system.
