EXPERIMENTS WITH A FILTRABLE VIRUS IN A TRANSFERABLE ILLNESS OF CANARY BIRDS
Abstract
A filterable virus (Berkefeld-N-Candle filter) is described, which occurred spontaneously in canaries and may cause epidemics. It is high pathogenic killing animals 100% in 7-12 days. Unusual forms occurred in blood of infected birds and appear to be related to infection. They may arise from altered, degenerated blood elements. The virus is still infectious at 0.000001 dilution; stable for 3 months in cold, but liable to 60C. IM transmission causes necrotic, degenerative alterations at the site of injection. It cannot be transferred to pigeons, chicks, chickens, but can be to sparrows. Virus may be latent in certain birds (finches) which might be classified as virus carriers.
