We examined extended-spectrum β-lactamase-producing isolates from livestock, humans, companion animals, food, and the environment during 2009-2016 in Germany for the presence of CTX-M-27 allele within Escherichia coli sequence type (ST) 131. E. coli ST131 C1-M27 was exclusively present in humans; its incidence increased from 0% in 2009 to 45% in 2016.
我们在 2009 年至 2016 年间对德国的家畜、人类、伴侣动物、食品和环境中的产超广谱β-内酰胺酶分离株进行了研究,以检测大肠杆菌序列型(ST)131 内 CTX-M-27 等位基因的存在情况。大肠杆菌 ST131 C1-M27 仅存在于人类中;其发生率从 2009 年的 0%增加到 2016 年的 45%。
