例句與用法
- Virulence genes of pathogenic bacteria can be located on the chromosome where they may be organized as so - called pathogenicity island ( pai )
細(xì)菌毒力島( pathogenicityisland ， pai )是指染色體上成簇排列的與細(xì)菌毒力密切相關(guān)的基因簇。 - The reason that different distribution frequency of hpi in various e . coli is unclear , either . as the high frequency distribution of hpi in eaggec , this study will focus on the following parts to discuss the function of yersiniae high - pathogenicity island in enteroaggregative e . coli
鑒于hpi在eaggec中的高頻分布，本研究擬從eaggec菌株出發(fā)，著重從以下幾個(gè)方面對(duì)eaggec攜帶的hpi毒力島的功能進(jìn)行了研究。 - The pathogenic strains of yersinia enterocolitica carry a 45 - kb high pathogenicity island ( hpi ) comprising iron - uptake - related genes such as irp1 - irp2 and fyua , which has been observed in 93 % of the 60 entero - adhesive e . coli { eaec } strains and 80 % of the e . coli isolated from blood samples
Hpi毒力島功能核心區(qū)主要的結(jié)構(gòu)基因?yàn)閕rp2 、 irp1和fyua ，是高度保守的。 irp2和irp1分別編碼兩種高分子量蛋白hmwp2和hmwp1 ， fyua編碼鼠疫菌素受體。 - Many pai have been discovered in many pathogens to humans ( pathogenic e . coli , yersiniae spp . , salmonella spp . , vibrio cholerae et al . ) - among them , the pai of yersiniae which encodes siderophore yersiniabactin ( ybt ) system is designated high - pathogenicity island ( hpi ) . hpi is essential for the mouse virulence in yersiniae
其中，耶爾森菌中的一個(gè)與鐵載體? ?耶爾森桿菌素( yersiniabactin , ybt )合成轉(zhuǎn)運(yùn)和調(diào)節(jié)有關(guān)的毒力島被稱為hpi毒力島( high - pathogenicityisland ， hpi ) 。 - 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(jié)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(yáng)性的大腸桿菌菌株，進(jìn)行在致瀉性大腸桿菌的25個(gè)毒力基因的檢測(cè)，包括腸產(chǎn)毒性大腸桿菌的熱穩(wěn)定毒素st和熱不穩(wěn)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(fā)現(xiàn)的毒力島基因。
