Transformation of uropathogenic Escherichia coli strains with plasmid DNA was in general unsuccessful or very inefficient. Transformation was much more efficient when galE mutants of such strains, in which the lipopolysaccharide chains appeared shorter, were used as recipients.
用质粒DNA转化尿路致病性大肠杆菌菌株通常不成功或效率非常低。当使用此类菌株的galE突变体(其脂多糖链显得较短)作为受体时,转化效率要高得多。
