A quantitative comparison of the antigenic structure of a virulent and an avirulent strain of Salmonella typhimurium
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.
