Abstract
Recovery of cell-culture-adapted infectious bursar disease virus (FK-78 strain)from feces and tissues of chickens infected experimentally with the virus was investigated. The virus was recovered from the feces, contents of caecum and jejunum, bursa of Fabricius, liver, spleen, thymus, kidney, and lung of chickens inoculated orally with the virus at 21 days of age. Virus titer was the highest in the bursa of Fabricius, and moderately high in the feces and the caecal contents. High virus titers were obtained 4 or 5 days after inoculation. On the other hand, the virus titers in the feces were influenced by the route of virus inoculation. High titers were obtained from chickens having received the virus orally or intranasally. The younger an inoculated chicken, the earlier the initial recovery of the virus from the feces of the chicken.
