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. |
