序列分析表明 :家蚕核型多角体病毒苏州株 (BmNPVsu)编码的ChiA基因的ORF为 16 5 6个核苷酸 ,编码 5 5 1个氨基酸。同源性分析表明 :杆状病毒编码的ChiA基因在DNA水平上、氨基酸水平上都具有较好的同源性 ,与灵菌的ChiA在氨基酸水平上的同源性达 47 8%~ 5 8 5 % ,推测杆状病毒编码的ChiA基因由细菌通过基因的水平转移而来。在杆状病毒ChiA的系统树中 ,舞毒蛾核型多角体病毒 (LdNPV)为一单独分枝 ,处于进化树的最根部 ,其余可分 2组 ,其中棉铃虫核型多角体病毒 (HaNPV)ChiA、谷实夜蛾核型多角体病毒 (HzNPV)ChiA为一组 ,其它杆状病毒的ChiA构成了第二组

Pathogenicity islands (Pais) are foreign DNA taken up via horizontal gene transfer by pathogenic microbes.

Objective To study the horizontal transfer of cholera toxin gene induced by CTAKΦ. Methods Bacterial strains were tested for the sensitivity to individual antibiotic with the disk diffusion technique to select several combinations of donation and acceptance strains for horizontal gene transfer. Several kinds of experiments were used to test the ability for donation strains to transfer the A RK R of CTAKΦ to acceptance strains. Results The donation strains FJ97129, DX29 transfered the A RK R of CTAKΦ to acceptance strains HK42, XJ93172, GD3188, 7763, 569B and 94001. However the acceptance strains IEM101 was resistant to infection of CTAKΦ. Conclusion The CTAKΦ can induce the horizontal transfer of cholera toxin gene. [
