The result of the study shows that the morbidity of the hospital infection in 305 elderly died cases dis- eases was 33.8%, The lungs were the first major site of the infection (66.9%) and followed by urinary tract infection (19.4%), The factors of high risk in- ducing hospital infection included advanced age invasive procedures, multi-antibiotics used in com- bination and hormonotherapy.

本文结果表明，305例老年死亡病例医院感染的发病率为33.8％。感染最多部位为肺部(66.9％)，其次为尿路感染(19.4％)。高龄患者，侵袭性操作、多种抗生素联合应用，激素疗法等是诱发医院感染的危险因素。58.8％的病原菌为革兰氏阴性杆菌，37.2％为真菌。31株病原菌药敏结果显示耐药率为33.3％。

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。
