In previous reports by the writer and others it has been shown that the resistance of a strain of mice to controlled infections of Salmonella acrtrycke could be greatly increased by selective breeding. After fourteen generations of selection for resistance to a standard close of 2 x 105 organisms the mortality in the selected stock (S) was only 8 per cent as compared with a mortality of approximately 98 per cent in the highly susceptible Silver (Sil) and Bagg albino (Ba) strains.
