Abstract

A total of 493 of Sa/mal/ella typh] were phage typed the most predominant among these being type F I. Kristensen reaction showed that the lysotypcs identified in Iran follow the same biochemical pattern as the lysotypes isolated in other countries. As observed in other areas a great majority of our strains also possess the tetrathionate reductase enzyme. Colicinogenc properly was found to be present in only one of Ihe strains. This strain was classified as not Iypable and belonged to group I IV xylose negative.
