Characteristics of <i>Erwinia</i> ‐like Organisms found in Plant Material

Abstract

Summary The characters of 20 nonpigmented and 2 yellow pigmented isolates of Ervinia ‐like organisms from plant material (primarily pome fruit) are described and compared with those of Erwinia amylovora . Cultures of some other Erwinia species were also included in the study for comparison. It is suggested, on the basis of their similarity to Erw. amylovora , that they should be included in the genus Erwinia , although they have no obvious pathogenic role. The relationship of these organisms with Erw. lathyri and Bacterium herbicola is discussed.
