ESTABLISHMENT OF A RABBIT LUNG CELL LINE (RL-33) AND ITS VIRAL SUSCEPTIBILITY

Abstract
A new cell line RL-33 was established from a rabbit lung tissue. The cells maintained a fibroblastic appearance and a contact-inhibited growth through 180 passages. No latent infectious agent was so far demonstrated. The cells supported the growth of a variety of viruses, enabling plaque assays for Shope fibroma, rabbit myxoma and types 1 and 2 herpes simplex viruses. They were as sensitive to rabbit interferon as RK-13 line from (a rabbit kidney) cells.
