Eosin methylene xiav agar ( EMB ) yog ib qho kev xaiv thiab sib txawv nruab nrab siv los cais cov quav coliforms. Eosin Y thiab methylene xiav yog pH qhov taw qhia dyes uas ua ke los tsim cov xim daj tsaus ntuj nag lossis daus ntawm pH qis; lawv kuj pab inhibit qhov kev loj hlob ntawm feem ntau Gram zoo kab mob.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov ua haujlwm ntawm eosin thiab methylene xiav hauv EMB media quizlet?
Nws muaj cov sib xyaw ntawm cov pa roj carbon, nitrogen, thiab lwm yam khoom noj muaj txiaj ntsig. Cov suab thaj suav nrog txhawm rau txhawb kev loj hlob ntawm cov kab mob nkag mus thiab siv los sib txawv cov kab mob raws li lawv cov xim tshwm sim tsim thaum ua ke nrog cov zas.
Ib sab saum toj no, cov khoom siv xaiv hauv EMB Agar yog dab tsi? Eosin methylene blue (EMB, tseem hu ua "Levine's formulation") yog cov xim xaiv rau cov kab mob Gram-negative. EMB muaj cov xim uas muaj tshuaj lom rau cov kab mob Gram-positive. EMB yog qhov kev xaiv thiab qhov sib txawv nruab nrab rau coliforms. Nws yog ib qho kev sib xyaw ntawm ob stains, eosin thiab methylene xiav hauv qhov sib piv ntawm 6: 1.
Kuj paub, puas Staphylococcus aureus loj hlob ntawm EMB agar?
Qee hom kab mob Salmonella thiab Shigella tuaj yeem ua tsis tiav loj hlob ntawm EMB Agar . Qee cov kab mob gram-positive, xws li enterococci, staphylococci cov tsos mob , thiab cov poov xab yuav loj hlob ntawm qhov nruab nrab no thiab feem ntau tsim cov ntsiab lus tseem ceeb. Tsis muaj kab mob, tsis muaj kab mob lactose-fermenting cov kab mob kuj yuav loj hlob ntawm qhov nruab nrab no.
Dab tsi ua rau eosin methylene xiav xaiv?
Eosin Methylene Xiav (los yog EMB ) Agar yog a Xaiv & Sib txawv nruab nrab. Cov xaiv thiab qhov sib txawv yog vim cov dyes Eosin Y thiab Methylene Xiav , thiab cov suab thaj lactose thiab sucrose hauv nruab nrab. Nws yog Xaiv vim nws txhawb qee cov kab mob kom loj hlob thaum inhibiting lwm tus.
