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
為探討攜帶小腸結腸炎耶爾森氏菌的hpi毒力島的大腸桿菌是否具有其他已知的毒力基因，選取82株由原位雜交和pcr方法初篩irp2陽性的大腸桿菌菌株，進行在致瀉性大腸桿菌的25個毒力基因的檢測，包括腸產毒性大腸桿菌的熱穩定毒素st和熱不穩定毒素lt ，腸侵襲性大腸桿菌的侵襲蛋白b基因ipab ，腸致病性大腸桿菌的eaf 、 espc基因，腸出血性大腸桿菌的溶血素hly 、志賀毒素1 （ slt1 ） 、志賀毒素2 （ slt2 ）基因，腸集聚性大腸桿菌的eaggec探針，以及在泌尿道致病性大腸桿菌和o157 ： h7大腸桿菌中新發現的毒力島基因。
