With Southern Blotting hybridization of R plasmid DNA with gentamycin resistant gene probe from America, Australia and our lab,a different gentamycin resistant gene was found and thd new gene was cloned into pBluescript SK( I ) vector.

• 应用源自美国、澳洲及本室的庆大霉素耐药基因探针对分离的庆大霉素耐药菌株进行Southern印迹杂交,又发现了另一种与之不同源的庆大霉素耐药基因,并对该基因进行了分子克隆和初步分析。
