  • 简介:目的构建肺炎链球菌自溶素(pneumococcalautolysin,LytA)核酸疫苗,并研究其免疫原性。方法采用聚合酶链反应方法从肺炎链球菌基因组中克隆肺炎链球菌自溶素基因,然后将该基因插入到pVAX1真核表达载体中,构建表达LytA的重组质粒,制备成超螺旋比例大于90%的核酸疫苗。实验组:BALB/c小鼠5只,对其分3次肌内注射核酸疫苗(100μg);对照组:BALB/c小鼠5只,肌内注射pVAX1空载体(100μg)3次。分别采集小鼠血清,采用间接酶联免疫吸附方法测定血清LytA特异性抗体水平。结果扩增出的LytA基因(957bp)与基因库中LytA的编码序列(957bp)一致。成功构建了LytA核酸疫苗。实验组小鼠的血清LytA抗体水平明显高于对照组,差异有统计学意义(P〈0.01)。结论成功克隆了LytA基因,制备了LytA核酸疫苗,后者可在小鼠体内诱导较强的特异性体液免疫反应。

  • 简介:目的:分析小儿先天性鼻泪管闭塞所致泪囊炎的病原及其药敏结果,指导临床合理用药。方法:对先天性鼻泪管阻塞患儿98例110眼的泪囊分泌物进行病原分离培养及药物敏感试验。结果:从94眼的分泌物中共分离出155株细菌,病原阳性率为85.5%。其中革兰氏阳性球菌65.8%,革兰氏阴性杆菌23.9%。分离出的所有菌株对左氧氟沙星的敏感率为94.2%。结论:药敏试验表明绝大多数细菌对左氧氟沙星有较高的敏感性,对于小儿先天性鼻泪管闭塞所致泪囊炎可给予新喹诺酮类抗生素滴眼液治疗。
