Qhov sib txawv tseem ceeb ntawm ETEC thiab EHEC yog tias ETEC yog kab mob ntawm cov kab mob E. coli thiab yog lub ntsiab ua rau cov neeg taug kev raws plab, thaum EHEC yog kab mob ntawm cov kab mob E. coli thiab yog lub ntsiab ua rau ntshav ntshav. mob plab.
ETEC thiab EHEC yog ob yam khoom noj loj uas ua rau muaj kev hem thawj rau pej xeem kev noj qab haus huv loj hauv cov tebchaws tau nyiaj tsawg thiab tsim kho, feem. Tsis tas li ntawd, cov kab mob E. coli cuam tshuam nrog kev mob plab hnyuv tau muab faib ua yim kab mob raws li cov kab mob virulence. Lawv yog EPEC (enteropathogenic E. coli), EHEC (enterohaemorrhagic E.coli), ETEC (enterotoxigenic E.coli), EIEC (enteroinvasive E.coli), EAEC (enteroaggregative E. coli), DAEC (diffusively adherent E. coli), AIEC (adherent invasive E.coli), thiab STEAEC (Shiga toxin-producing enteroaggregative E. coli)).
ETEC yog dab tsi?
ETEC yog ib qho tseem ceeb ua rau muaj kab mob raws plab. ETEC yog ib hom kab mob ntawm E.coli kab mob, uas yog lub ntsiab ua rau cov neeg taug kev raws plab. Nws kuj yog ib qho tseem ceeb ntawm cov kab mob raws plab hauv cov teb chaws tau nyiaj tsawg, tshwj xeeb tshaj yog cov menyuam yaus. ETTC tus kab mob kis tau los ntawm cov zaub mov lossis dej kis nrog tsiaj lossis tib neeg quav. Cov kab mob no tuaj yeem tiv thaiv tau los ntawm kev npaj zaub mov thiab dej haus kom muaj kev nyab xeeb uas tuaj yeem kis tau los ntawm ETEC pathotype. Ntxiv mus, kev ntxuav tes kom zoo kuj tseem tuaj yeem tiv thaiv tus kab mob ETEC no.
Daim duab 01: ETEC
ETEC tsim ob yam tshwj xeeb co toxins (ST-heat ruaj khov toxin thiab LT-heat labile toxin) uas txhawb nqa cov hnyuv hauv ob sab phlu kom tso kua dej ntau dhau, ua rau raws plab. ETEC thawj zaug tau lees paub tias yog qhov ua rau tib neeg mob raws plab hauv xyoo 1960. Tus kab mob los ntawm ETEC tuaj yeem ua rau muaj mob raws plab, mob plab, ua npaws, xeev siab, nrog lossis tsis ntuav, ua daus no, tsis qab los noj mov, mob taub hau, mob leeg, thiab tsam plab.
ETEC tus kab mob tuaj yeem kuaj tau los ntawm tus neeg mob keeb kwm, cov tsos mob, thiab kab lis kev cai ua los ntawm cov qauv ntawm cov quav. Tsis tas li ntawd, cov kev kho mob rau ETEC cov kab mob yuav suav nrog kev muab cov kua dej ntshiab los tiv thaiv lub cev qhuav dej, cov ntsev ua kom rov qab los yog cov tshuaj ua kom lub qhov ncauj ua ntej, cov tshuaj bismuth subsalicylate, tshuaj tiv thaiv kab mob, thiab tshuaj tua kab mob (trimethoprim-sulfamethoxazole, fluoroquinolones).
EHEC yog dab tsi?
EHEC yog ib hom kab mob ntawm cov kab mob E. coli thiab yog qhov ua rau mob raws plab. EHEC yog qhov kev txhawj xeeb tseem ceeb rau pej xeem kev noj qab haus huv hauv cov tebchaws tsim kho. Nws yog tus thib peb feem ntau zoonotic kab mob nyob rau hauv cov teb chaws Europe, txuam nrog loj zaub mov lom tshwm sim nyob rau hauv cov teb chaws Europe, lub teb chaws USA, Canada, thiab Nyiv. EHEC yog tus kab mob E. coli uas tsim cov tshuaj lom hu ua Shiga toxin. Cov tshuaj lom no ua rau muaj kev puas tsuaj rau cov kab mob ntawm cov hnyuv. Xyoo 1982, EHEC tau tshawb pom tias yog qhov ua rau mob raws plab uas tshwm sim tom qab noj cov nqaij hamburger tsis qab los yog nyoos. Cov tsos mob ntawm EHEC cov tsos mob yuav muaj xws li mob plab, mob plab heev, raws plab, tsis muaj ntshav, me ntsis ua npaws, qaug zog, xeev siab, thiab hemolytic uremic syndrome (HUS).
Ib tus kab mob EHEC tuaj yeem kuaj tau los ntawm kev kuaj lub cev, kev coj noj coj ua ntawm cov quav, kev kuaj quav sai rau shiga toxin, thiab X-ray. Cov kev xaiv kho mob rau tus kab mob EHEC yuav suav nrog kev saib xyuas kev txhawb nqa, haus dej kom ntau los tiv thaiv lub cev qhuav dej, hloov ntshav, thiab raum lim ntshav.
Dab tsi yog qhov zoo sib xws ntawm ETEC thiab EHEC?
- ETEC thiab EHEC yog ob yam khoom noj loj uas ua rau muaj kev hem thawj rau pej xeem kev noj qab haus huv loj hauv cov tebchaws tsim thiab tsim.
- Ob leeg yog ob hom kab mob tseem ceeb ntawm cov kab mob coli cuam tshuam nrog kev mob plab
- Ob tus kab mob ua rau muaj co toxins.
- Lawv ua rau mob plab.
Qhov txawv ntawm ETEC thiab EHEC yog dab tsi?
ETEC yog ib hom kab mob E.coli thiab yog qhov ua rau cov neeg taug kev raws plab, thaum EHEC yog tus kab mob E.coli thiab yog qhov ua rau mob raws plab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ETEC thiab EHEC. Tsis tas li ntawd, ETEC pathotype tsuas yog muaj tib neeg lub pas dej ntawm tus kab mob xwb, thaum EHEC pathotype yog tus kab mob zoonotic.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm ETEC thiab EHEC hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – ETEC vs EHEC
ETEC thiab EHEC yog ob hom kab mob tseem ceeb ntawm E. coli kab mob cuam tshuam nrog kev mob plab hnyuv. ETEC yog qhov laj thawj tseem ceeb ntawm cov neeg taug kev raws plab, thaum EHEC yog qhov ua rau mob raws plab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ETEC thiab EHEC.
