title: Phylogeny of strains of Salmonella typhimurium.
abstract: The combined use of biotyping and phage typing has been used to identify major clones of Salmonella typhimurium. Recombination studies among isolates of different clones indicate their genetic relatedness and allow construction of a phylogenetic tree showing relationships among major biotypes. Possible lines of their descent from a common archetypal ancestor are discussed.
