Escherichia coli O157 isolates from cattle in Japan (n = 91) and in the USA (n = 415) were compared by pulsed-field gel electrophoresis of endonuclease-cleaved genomic DNA, location of the stx genes and bacteriophage typing. Three isolates from cattle in Japan with high similarity to isolates from cattle in the USA were found. Isolates from cattle farms in Japan and the USA may share a common source.
通过对核酸内切酶切割的基因组DNA进行脉冲场凝胶电泳、stx基因定位和噬菌体分型，比较了来自日本（n = 91）和美国（n = 415）牛的大肠杆菌O157分离株。发现来自日本牛的3株分离株与来自美国牛的分离株高度相似。来自日本和美国养牛场的分离株可能有共同来源。
