Escherichia coli O157:H7 was recovered from colon fecal samples of pigs. Polymerase chain reaction confirmed two genotypes: isolates harboring the eaeA, stx(1), and stx(2) genes and isolates harboring the eaeA, stx(1), and hly(933) genes. We demonstrate that swine in the United States can harbor potentially pathogenic E. coli O157:H7.
从猪的结肠粪便样本中分离出了大肠杆菌O157:H7。聚合酶链反应证实了两种基因型：携带eaeA、stx(1)和stx(2)基因的分离株以及携带eaeA、stx(1)和hly(933)基因的分离株。我们证明，美国的猪可能携带具有潜在致病性的大肠杆菌O157:H7。
