| Abstract: | Abstract Extract In a previous publication dealing with the active immunity of mice to Salmonella typhimurium, it was shown that, by varying the interval of time between vaccination and challenge, two phases of increased resistance were observed (Jonas, 1967a Jonas, W. E. 1967a. Studies on the immunological aspects of salmonellosis of mice. Active immunity. N.Z. vet. J., 15: 27–30. [Taylor &; Francis Online] , [Google Scholar]). Phase I resistance occurred from 3 to 11 days after vaccination and phase II from 15 to 21 days. |
