Infection of chicken erythrocytes with influenza and other viruses

Abstract
Chicken erythrocytes can be infected by the fowl plague (Rostock) strain (FP/R) of influenza type A, Newcastle disease virus (NDV) and Semliki Forest virus (SFV). Only NDV and SFV produced infectious progeny, although at low levels. Infection by FP/R was monitored by de novo synthesis of viral proteins and the proteins synthesized could be identified by comparison with infected chicken fibroblast cells. FP/R synthesized far greater amounts of viral protein than did NDV or SFV.
