| Description | Citation typed |
| Citation | Distinguished for his many contributions to knowledge in the field of bacterial genetics and physiology, especially with respect to the structure and function of flagella. His study of phase variation of flagellar antigens in Salmonella first demonstrated drift towards mutational equilibrium in growing bacterial populations. He discovered the phenomen of abortive transduction, which has been a major tool in the analysis of genetic fine stricture, and developed methods for the pedigree analysis of single cell lines of bacteria. By this means he established the hypothesis that the abortive transduction of motility is due to the uni-linear inheritance, for many generations, of a non-replicating but functional genetic determinant. His study of colicin factors (which determine the production of certain bacterial antibiotics as well as their own transmission by promoting conjugation) led him to a new method of obtaining chromosome transfer and genetic recombination in Salmonella, and to the discovery that the linkage group of this organism is continuous. His recent work on the somatic polysaccharide of Salmonella has clarified the genetical and biochemical nature of 'smooth-rough' variation, as well as the antigenic changes resulting from infection by some bacteriophages. |
