Characteristics ofErwinia‐like Organisms found in Plant Material

摘要

SummaryThe characters of 20 nonpigmented and 2 yellow pigmented isolates ofErvinia‐like organisms from plant material (primarily pome fruit) are described and compared with those ofErwinia amylovora. Cultures of some otherErwiniaspecies were also included in the study for comparison. It is suggested, on the basis of their similarity toErw. amylovora, that they should be included in the genusErwinia, although they have no obvious pathogenic role. The relationship of these organisms withErw. lathyriandBacterium herbicolais discusse
