Swiss white mice immunized with acetone-killed vaccines prepared from strains of Salmonella typhosa, S. typhimurium, and mouse-virulent S. typhimurium hybrids which had acquired, by conjugal genetic transfer, the S. typhosa antigens 9, Vi, and d were challenged with the S. typhimurium hybrids and with the S. typhimurium parent strain. The results of these experiments suggested that the Salmonel...

Bacterial recombination, first demonstrated with the K-12 strains of Escherichia coli by Tatum and Lederberg,I has provided a versatile technique for the investigation of genetic organization in bacteria.2-4 Recently, the sexual compatibility of bacteria from different genera has been extended to include hybridization between E. coli and Shigella,5 and between E. coli and Salmonella.6' I Only E...
متن کاملAn aminohexuronic acid as the principal hydrolytic component of the Vi antigen.
The Vi antigen is a major immunogenic component of Salmonella typhosa and has been prepared from three generically different bacterial species, Escherichia coli, Paracolobactrum ballerup, and X. typhosa (2). A comparison of certain chemical and physical properties of the purified antigens was made, and the values were similar except for significant differences in viscosity. The Vi antigens were...
