Ib yam li ntawd, vim li cas mycobacteria thiaj li acid sai?
Cov no Acid - ceev kab mob zoo li Mycobacterium Muaj ntau cov lipid tshuaj nyob rau hauv lawv cov phab ntsa ntawm tes hu ua mycolic kua qaub . Cov no kua qaub tiv thaiv staining los ntawm cov txheej txheem zoo ib yam li Gram Stain. Nws kuj tseem siv tau los stain ob peb lwm cov kab mob, xws li Nocardia. Acid - ceev bacilli yog xim liab tom qab ziab.
Ib tus kuj tseem yuav nug tau tias, txhais tau li cas los ntawm lo lus acid sai? Acid -fastness yog ib yam khoom ntawm lub cev ntawm cov kab mob, tshwj xeeb tshaj yog lawv tsis kam mus decolorization los ntawm kua qaub thaum txheej txheem txheej txheem. Thaum stained, cov kab mob no tiv taus lub dilute kua qaub thiab/lossis txheej txheem de-colorization txheej txheem ethanol ntau nyob rau ntau qhov txheej txheem staining-li lub npe kua qaub - ceev.
Tsis tas li ntawd, vim li cas Mycobacterium tuberculosis hu ua acid ceev?
Cov lus teb tsis ntev los no. Mycobacteria yog npe acid - ceev vim lawv tawm tsam decolorization nrog kua qaub cawv vim qhov xwm ntawm lawv cov phab ntsa complex.
