Immunization of rabbits to infectious papillomatosis

Abstract

TWO intraperitoneal injections of either infectious or non-infectious rabbit papilloma suspensions actively immunize rabbits against papillomatosis. The capacity of the non-infectious suspensions to immunize is considered as evidence that they contain papilloma virus even though none can be demonstrated by the usual infection test. © 1937, Rockefeller University Press., All rights reserved.
