Abstract
From Escherichia coli strains, ColE1-ML and ColV-K94 factors were transferred to a virulent Shigella flexneri 2a strain at 1-2% frequency. S. flexneri ColV+ and ColE1+V+ produced Col- segregants. The ColE1 factor was stably incorporated into S. flexneri. The ColV+ culture lost its virulence to the guinea pig eye.
摘要
从大肠杆菌菌株中，ColE1-ML和ColV-K94因子以1%-2%的频率转移至强毒弗氏志贺菌2a菌株。弗氏志贺菌ColV+和ColE1+V+产生了Col-分离株。ColE1因子稳定整合入弗氏志贺菌。ColV+培养物对豚鼠眼失去了毒力。
