食品卫生微生物学检验小肠结肠炎耶尔森氏菌检验 - The results showed that the f fragment , 728bp in length , could be a new gene with a little homology to the genes coding for polyketide synthetase or fatty - acid synthetase and the b fragment , about 4kb in length , is inferred to have repeat sequences around tn5 insertion site , in which there is homology to the wa 314 right arm of the high - pathogeniciry island of yersinia enterocolitica . to reveal any pathogenicity of enterobacter cloacae b8 and its mutated strains b8b and b8f to animals , the experiment with mice was carried out
结果显示， f片段长度为728bp ，与现有生物数据库的blast比较分析，发现该序列仅有局部短于1oobp的区域与polyketide合成酶基因或与脂肪酸合成酶基因有低的同源性，推测为一新基因； b片段长约4kb ，序列拼接结果推测靠近tn5插入位点部位有重复序列，对b片段tn5远端的部分序列进行blast比较，发现它与小肠结肠炎耶尔森氏菌的强毒力岛有一定的同源性。 - To dress the question if other virulence gene were present in this kind of strains , 152 of 436 irp2 - hybridized strains were re - confirmed and selected for this study . the virulence genes or putative virulence genes detected by pcr or hybridization include heat stable toxin ( st ) & heat labile toxin ( lt ) for enterotoxigenic e . coli ( etec ) , invasive plasmid antigen b ( ipab ) for enteroinvasive e . coli ( eiec ) , epec adherence factor ( eaf ) , epec secretion protein c ( espc ) for enteropathogenic e . coli ( epec ) , hemolysin ( hlya ) and shiga toxins ( sltl and slt2 ) for enterohaemorrhagic e . coli ( ehec ) and eaggec probe for entero - aggregative e . coli ( eaggec ) . the prra and yc73 genes of pathogenicity associated island ( pai ) of urepathogenic e . coli ( upec ) and " o " island 28 ( rtx 615 ) gene was also detected , the later was a newly discovered putative pathogenicity island in e . coli o157 : h7
为探讨携带小肠结肠炎耶尔森氏菌的hpi毒力岛的大肠杆菌是否具有其他已知的毒力基因，选取82株由原位杂交和pcr方法初筛irp2阳性的大肠杆菌菌株，进行在致泻性大肠杆菌的25个毒力基因的检测，包括肠产毒性大肠杆菌的热稳定毒素st和热不稳定毒素lt ，肠侵袭性大肠杆菌的侵袭蛋白b基因ipab ，肠致病性大肠杆菌的eaf 、 espc基因，肠出血性大肠杆菌的溶血素hly 、志贺毒素1 ( slt1 ) 、志贺毒素2 ( slt2 )基因，肠集聚性大肠杆菌的eaggec探针，以及在泌尿道致病性大肠杆菌和o157 ： h7大肠杆菌中新发现的毒力岛基因。
