Effect of ethylene diamine tetraacetate (EDTA) on the interferon-inducing activity of Newcastle disease virus (NDV) in vivo. Brief report.

Circulating interferon levels increased and persisted for prolonged periods of time when groups of mice were stimulated with a mixture of Newcastle disease virus (NDV) and EDTA, or pretreated with EDTA and then injected with NDV, instead of injection with NDV alone.
