Zhongguo shiyan zhenduanxue, 2009 目的为鉴定伤寒沙门菌的耐药性获得与整合子之间的关系,确定该菌抗性基因扩散的可能机制。方法我们选取32株多药耐药的伤寒沙门菌株提取全基因组DNA,扩增整合子,并以此作为模板检测抗性基因。结果以伤寒沙门菌基因组DNA为模板有81.2%的菌株,能够扩增出相应整合子的目的片段。具有四环素抗性、氨苄青霉素抗性和复方磺胺抗性的样品,以其扩增产物作为模板全部能扩增出相应抗性基因suⅡ、blaTEM-1和tetG。结论伤寒沙门菌的抗性基因是整合在Ⅰ类整合子中的,故整合子的转移应是伤寒沙门菌抗性基因传递的一种主要途径。

Zhongshan Daxue xuebao. Yixue kexue ban, 1994 以异硫氰酸胍裂解血清释放核酸使被二氧化硅吸附，经乙醇洗涤后用水悬浮，上清即含纯化ＤＮＡ。结合双阶变温ＰＣＲ建立一种简单快速的血清ＨＢＶ－ＤＮＡ检测方法。该法只需检测１０ｕｌ血清，完成提取和扩增只要３ｈ．操作很易掌握。用之检测５６例ＨＢｓＡｇ＋／ＨＢｅＡｇ＋的血清、４２例ＨＢｓＡｇ＋／ＨＢｅＡｇ－的血清和５４例ＨＢｓＡｇ／ＨＢｅＡｇ的血清，结果ＨＢＶ－ＤＮＡ检出率分别为８６％、５７％和１３％。应用表明这是一种简捷有效的核酸纯化和扩增方法，适于对大量临床样本作检测之用。
