Enterobacter hom muaj peev xwm siv sodium citrate raws li qhov tsuas yog cov pa roj carbon thaum E . Citric acid los yog nws cov ntsev yog sodium siv raws li ib qho chaw ntawm carbon thiab ammonium ntsev raws li ib qho chaw ntawm nitrogen los ntawm E . aerogenes thaum E . coli cov ua tsis siv cov ntsev thiab li no tsis loj hlob.
Tom qab ntawd, ib tus tseem yuav nug, puas yog Enterobacter aerogenes indole zoo?
Klebsiella aerogenes , yav tas los hu ua Cov kab mob Enterobacter aerogenes , yog Gram-negative, oxidase negative, catalase zoo , citrate cov zoo , indole Cov kab mob tsis zoo, tus kab mob rod. aerogenes yog cov kab mob nosocomial thiab kab mob uas ua rau muaj kev kis kab mob suav nrog ntau hom kev kis mob.
Qhov thib ob, lub hom phiaj ntawm kev ntsuas siv citrate yog dab tsi? Kev siv Citrate Test (Simmons) Lub lub hom phiaj yog saib seb lub microbe tuaj yeem siv cov khoom sib xyaw citrate raws li nws qhov chaw ntawm carbon thiab lub zog rau kev loj hlob. Yog li cas citrate siv txiav txim? Yog tias microbe tuaj yeem siv tau citrate rau carbon thiab zog, nws yuav loj hlob ntawm Simmons citrate agar.
Ib yam nkaus, puas yog E coli siv citrate?
Nws tseem tuaj yeem loj hlob anaerobically los ntawm fermenting citrate . Txawm li cas los xij, nws tsis tuaj yeem loj hlob aerobically citrate vim nws ua tsis tsim cov protein thauj khoom thaum muaj oxygen uas tuaj yeem nqa tau citrate mus rau hauv lub cell. E . coli ua muaj a citrate transporter hu ua CitT, tab sis nws tsuas yog qhia thaum tsis muaj oxygen.
Puas yog Enterobacter aerogenes yog lactose fermenter?
Cov kab mob no ferment cov lactose , yog motile, thiab tsim mucoid colonies. Enterobacter hom kab mob feem ntau tshwm sim los ntawm cov kab mob hauv lub cev endogenous ntawm cov neeg mob hauv tsev kho mob tab sis tuaj yeem tshwm sim hauv qhov chaw sib kis los yog kis los ntawm tus neeg mob mus rau tus neeg mob.

Koj puas tuaj yeem ua ntau npaum li ib feeb thib ob raws li koj tuaj yeem ua thawj zaug?
Koj tuaj yeem ua ntau npaum li cas hauv ib feeb thib ob li koj ua tau thawj zaug? Tsis yog. Muab cov lus piav qhia txog keeb kwm ntawm cov txiaj ntsig no. Qhov no yog vim qhov ntau koj ua ib qho kev ua si, qhov ntau lactic acid tsim, thiab ntau oxygen koj yuav tsum tau them rov qab cov lactic acid vim lactic acid ua rau mob rau lub cev
Puas yog Enterobacter aerogenes tsim roj?
Cov pas nrig zoo li Enterobacteriaceae muaj nyob rau hauv ntau qhov ntau thiab tsawg; tsis spore tsim; yog ob leeg ua haujlwm (nrog peritrichous flagella) lossis tsis txav chaw; loj hlob ob qho tib si aerobically thiab anaerobically; yog active biochemically; ferment (piv rau oxidize) D-piam thaj nrog rau lwm cov suab thaj, feem ntau nrog cov khoom siv roj; txo nitrate rau
Puas yog Enterobacter aerogenes txaus ntshai?
Enterobacter aerogenes yog tsev kho mob-tau txais thiab cov kab mob pathogenic uas ua rau kis mob. Nws yog cov kab mob Gram-negative zoo li tus kab mob uas ua rau muaj kev tiv thaiv ntau dua rau cov tshuaj tua kab mob. E. aerogenes feem ntau pom muaj nyob hauv tib neeg txoj hnyuv thiab tsis feem ntau ua rau muaj kab mob hauv cov tib neeg noj qab nyob zoo
