Abstract
Two strains of Salmonella typhimurium differing greatly in virulence for mice have been examined by various means for their quantitative content of the antigenic determinants 4, 5 and 12. By three methods the virulent strain consistently revealed a content of each of these antigens approximately twice that of the avirulent strain. The implications of this finding for the interpretation of factors involved in bacterial virulence are discussed.
