Twelve strains of Escherichia coli O157:H7 were isolated from 9 of 25 beef samples purchased from retail stores in Malaysia. These strains produced Shiga toxin 2 with or without Shiga toxin 1 and had the eae gene and a 60-MDa plasmid. The antibiograms and the profiles of the arbitrarily primed PCR of the strains were diverse, suggesting that the strains may have originated from diverse sources.
从马来西亚零售店购买的25份牛肉样本中的9份中分离出了12株大肠杆菌O157:H7。这些菌株产生志贺毒素2,有或没有志贺毒素1,并且具有eae基因和一个60兆道尔顿的质粒。这些菌株的抗菌谱和随机引物PCR图谱各不相同,表明这些菌株可能起源于不同的来源。
