An effective etec oral vaccine can evoke responses of anti - colonization and anti - toxin 一個(gè)有效的etec口服疫苗必須能夠激起抗定居以及抗毒素兩方面的免疫反應(yīng)。
Etec can adhere to the epithelial by means of proteinaceous surface structures called colonization factors ( cfs ) to cause diarrhea 它在致病時(shí)是通過定居因子蛋白表面結(jié)構(gòu)粘附到腸上皮細(xì)胞表面,然后分泌腸毒素致病。
Vibrio cholerae and enterotoxigenic escherichia coli ( etec ) are major pathogens that evoke acute diarrhea among children worldwide and travelers to developing countries 霍亂毒素與毒素大腸桿菌( etec )是引起嬰幼兒和旅游者腹瀉的主要病原菌。
If etec vaccine contains colonization factor antigen such as cfa / i and cs1 - cs6 , associating with enterotoxin ( lt ) , it can , theoretically , protect the user from diarrhea by percent 80 etec attacking 如果一個(gè)疫苗包含有定居因子抗原和lt腸毒素,則理論上可使服食者免受80的etec菌株的侵害。
To produce the multicomponent vaccine against diarrhea , a translational fusion with the cholera toxin b subunit ( ctb ) upstream of cs3 , which is one of the prevalent colonization factors ( cfs ) found in human etec strains , was constructed 為研制有效的廣譜亞單位疫苗,將霍亂毒素b亞單位( ctb )和etec的優(yōu)勢抗原之一cs3分別作為抗毒素免疫和抗黏附免疫的免疫抗原。
A . dissolved oxygen in situ treatment ( do - it ? ) is a complicated bioremediation approach that utilizes etec ' s proprietary biological products and oxygenation technology for rapid , consistent biological cleanup of soil and groundwater 答:溶解氧就地處理是一種復(fù)雜的生物修復(fù)方法。它將本公司專利生物產(chǎn)品和增氧技術(shù)相結(jié)合,迅速地、穩(wěn)定地對污染的土壤和地下水進(jìn)行就地生物清除。
Css is the one of the colonization factor antigens which is a protective antigen can cause immune reaction by the means taking orally . in this study , carrot was separately transformed with agrobacterium tumefacience strain lba4404 that contains ctb or ctb - cs3 fused gene in order to get oral diarrhea vaccine . this is a potent strategy to produce etec oral vaccine 本研究期望通過農(nóng)桿菌轉(zhuǎn)化系統(tǒng)將ctb (霍亂毒素b亞基,可作為佐劑和載體)基因和ctb - cs3融合基因分別轉(zhuǎn)入胡蘿卜植株,使ctb和ctb ? cs3融合基因穩(wěn)定整合到胡蘿卜基因組內(nèi),希望以此獲得以胡蘿卜為受體的etec口服疫苗,使服食者在進(jìn)食的同時(shí)就可獲得腹瀉免疫。
We determine the growth process and mutual relationship of three bacteria , i . e . photosynthetic bacteria , e . coli ki2 and etec 987p . relationship between pathogenic bacteria in water , aeromonas hydrophija , and phoiosynthetic bacteria was studied emphatically . the result showed that when inoculating quantity of phoiosynthetic bacteria was one fifth of that of aeromonas hydrophila , the growth of latter bacteria could be inhibited distinctly 其次,研究了混合生長體系的細(xì)菌色譜行為,實(shí)時(shí)對混合培養(yǎng)體系中每一種細(xì)菌的生長情況作出定量和定性的分析,確定了光合細(xì)菌、 e . colik12和etec987p三種細(xì)菌混合生長的過程及相互競爭與抑制的作用關(guān)系;針對水體中病原菌? ?嗜水氣單胞菌,重點(diǎn)考察了它與光合細(xì)菌的作用關(guān)系,結(jié)果表明光合細(xì)菌的接種量為氣單胞菌的1 5時(shí),就能夠?qū)鈫伟忻黠@的抑制效果。
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,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。
