We report a patient with neonatal meningitis caused by a CTX-M-1-producing Escherichia coli K1 strain. The influence of CTX-M production on virulence was investigated in cell culture and a newborn mouse model of meningitis. CTX-M production had no influence on virulence but was a major factor in clinical outcome.
我们报告了一例由产 CTX-M-1 大肠杆菌 K1 株引起的新生儿脑膜炎患者。在细胞培养和新生鼠脑膜炎模型中,研究了 CTX-M 产生对毒力的影响。CTX-M 的产生对毒力没有影响,但却是临床结果的主要因素。
