Abstract
A strain of Salmonella typimurium LT2 has been isolated which carries an insertion of approximately 700 bp in the gpt gene. The insertion in the gpt gene was shown to be the Salmonella-specific element IS200. The mutation in strain CR1 arose without selection during storage and is only the second phenotypically identified mutation caused by the insertion of IS200.
摘要
已分离出一株鼠伤寒沙门氏菌LT2，其gpt基因中有一段约700 bp的插入序列。gpt基因中的插入序列被证明是沙门氏菌特异性元件IS200。CR1菌株中的突变在储存期间未经选择就出现了，并且是由IS200插入引起的第二个表型鉴定突变。
