뽕나무에서 Erwinia carotovora subsp. carotovora의 분리
Pathogenicity and Bacteriological Characterization of Erwinia carotovora subsp. carotovora isolated from Mulberry Trees
초록
가을철 가지뽕 수확 후 가지의 절단부위 가운데 건증상을 띤 병$에서 Erwinia carotovora subsp. carotovora가 분리 동정되었다. 1)본 세균은 간장으로 4-8개의 주성모를 가진 0.4-0.8
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.
