title: Bacteriophage typing scheme for Salmonella infantis.
abstract: A bacteriophage typing system is described for Salmonella infantis. Nine phages were selected, of which three were isolated from sewage and six from human feces. All except 7 of the 546 strains collected between 1974 and 1978 could be classified into 23 different phage types. The five most common phage types comprised 26, 13, 9, 9, and 9% of all strains, respectively. Strains from humans, animals, food, and water isolated during nine episodes, or from given patients at different intervals of time, belonged to the same phage type.
