Chickens free of exogenous avian leukosis virus (ALV) infection, replicating endogenous ALV (Rous-associated virus-O), gs antigen, and chick helper factor were fully susceptible to induction of Marek's disease (MD) by ALV-free MD viruses. Dual infect

Use of Marek's disease virus (MDV) in a neutralization test presents several problems, which are described, making this potentially useful test difficult. To obviate these difficulties, a plaque reduction test has been designed based on cross-neutral

EXPERIMENTS conducted by Hudson (1931) with bronchitis virus infected chicks showed that mortality was 60 percent for those group maintained at 66°F. as compared to 32 percent for the 100°F. groups. In an experiment conducted at 75°F. involving in
