title: Effects of chicken anemia virus on macrophage function in chickens.
abstract: One-day-old chicks were inoculated intramuscularly with chicken anemia virus (CAV). Four birds were killed at 7, 14, 21, 28, and 42 days postinoculation (PI), and macrophages were recovered from spleen and bone-marrow suspensions. These were tested for interleukin-1 (IL-1) production, Fc receptor expression, phagocytosis, and bactericidal activity. Macrophages recovered from uninoculated chickens at the same sample times, and exposed to CAV in vitro, were also tested. IL-1 production, Fc receptor expression, phagocytosis, and bactericidal activity were significantly lower in all macrophage cultures from CAV-inoculated chickens, and in cultures exposed to the virus in vitro, than in uninfected controls.
