CONTROL OF SALMONELLA IN POULTRY BY RADIOVACCINE

Abstract

A radiovaccine was prepared from Salmonella typhimurium and Salmonella gallinarum cells killed by 5 kGy dose of gamma radiation. This vaccine induced an antibacterial response in chicks. Immunized chicks progressively eliminated the challenged organisms and no salmonellae could be isolated after a period of 35 days. In contrast, chicks from the control group harbored Salmonella The vaccine may find an application in raising “Salmonella free poultry”.
