Studies on the experimental typhoid

Nippon Saikingaku Zasshi, 1958
The mouse super-immunized with live vaccine of Salmonella enteritidis resisted intravenous injection of 1, 000 MLD of the same organism (Japan. J. Exp. Med., 30, 375-384). This anti-lethal resistance of mouse against the infection with S. enteritidis lasted for 16 months after the last injection of live vaccine (Japan. J. Exp. Med., 31, 187-190).
