title: Susceptibility of day-old chicks and ducklings, goslings and quails to pigeon herpes encephalomyelitis and pigeon herpesviruses.
abstract: Day-old chicks were susceptible to pigeon herpes encephalomyelitis virus (PHEV) by intracerebral (i/c) inoculation. Infected birds developed neurologic signs starting from 2 to 15 days post-infection, and 85% died. The virus was recovered from the brains of diseased chicks in titers ranging between 104 and 105.5 EID 50/0.2 ml. Inoculated birds shed the virus in their droppings throughout the 2 weeks observation period. Day-old chicks given the virus by the intranasal (i/n) or oral routes did not develop any specific signs but shed the virus also in their droppings throughout the observation period. Ducklings and goslings inoculated intravenously (i/v), i/n or orally were resistant. Day-old chicks and ducklings, goslings and quails inoculated by different routes with pigeon herpesvirus (PHV) did not show respiratory or nervous signs.
