Pathogenicity and Bacteriological Characterization of Erwinia carotovora subsp. carotovora isolated from Mulberry Trees
뽕나무에서 Erwinia carotovora subsp. carotovora의 분리
Abstract
The bacteria isolated from mulberry trees which had shoot soft rot symptoms occurred after intermediate cutting during autumn rearing season were indentified. External morphology of the bacteria showed rod shape with peritrichous flagella, and were facultative anaerobes in oxygen requirement test. The baacteria easily putrefied the slices of potato and carrot when they were placed on to the center of sliced surfaces, and the bacteria, also, iniciated rapid development of soft rot symptoms on mulberry leaves in pathogenesity test. The results of morphological, physiological and pathological tests on the bacteria suggested that the isolate could be a strain of Erwinia carotovora subsp. carotovora.
