A Salmonella enterica serovar Typhimurium strain that harbored a plasmid carrying a TEM-1-type beta-lactamase gene was isolated from the blood and cerebrospinal fluid of an infant with meningitis. This 3.2-kb plasmid was further characterized to be a nonconjugative pGEM series cloning vector containing a foreign insert. The strain was likely laboratory derived and contaminated the environment before it caused the infection.
从一名患脑膜炎婴儿的血液和脑脊液中分离出一株携带含有TEM-1型β-内酰胺酶基因质粒的肠炎沙门氏菌鼠伤寒血清型菌株。这个3.2kb的质粒经进一步鉴定为一个含有外源插入片段的非接合型pGEM系列克隆载体。该菌株很可能来源于实验室,在引起感染之前污染了环境。
