Hemolysins tau yog li ntawd ib txwm suav tias yog qhov xwm txheej phem txawm hais tias kev sim ua pov thawj ncaj qha rau qhov kev xav no yog qhov tsis zoo lossis tsis muaj. Feem ntau hemolysins ua rau lysis ntawm erythrocytes los ntawm kev tsim pores ntawm txawv diameters nyob rau hauv daim nyias nyias.
Hemolysins ua li cas thiaj li ua rau muaj kev phom sij?
Kev tshawb pom ntxiv qhia tau tias qhov tseem ceeb ntawm kev ua phem ntawm S. aureus, lub pore-forming toxin α-hemolysin (Hla), yog qhov zais cia ua lub luag haujlwm rau kev ua kom muaj lwm txoj hauv kev autophagic. … Hemolysins kuj tseem tuaj yeem nruab nrab cov kab mob khiav tawm ntawm cov cell.
Dab tsi yog suav tias yog qhov ua phem?
Cov khoom uas tsim los ntawm cov kab mob thiab cov kab mob evoke yog hu ua virulence factor. Piv txwv yog cov co toxins, cov coated nto uas inhibit phagocytosis, thiab nto receptors uas khi rau host cells.
Vim li cas Exoenzymes suav hais tias yog qhov ua phem?
Virulence factors pab kom tus kab mob muaj peev xwm ua rau kab mob Exoenzymes thiab co toxins tso cai rau cov kab mob nkag mus rau cov ntaub so ntswg thiab ua rau cov ntaub so ntswg puas. Exoenzymes raug cais raws li macromolecule lawv lub hom phiaj thiab exotoxins raug cais raws li lawv cov txheej txheem ntawm kev ua.
Puas yog endotoxins virulence yam?
Lub Ntsiab Lus Tseem Ceeb thiab Cov Ntsiab Lus. Virulence yam ua rau tus kab mob muaj peev xwm ua tau kab mob. Exoenzymes thiab co toxins tso cai rau cov kab mob nkag mus rau cov ntaub so ntswg thiab ua rau cov ntaub so ntswg puas. Cov kab mob co toxins suav nrog endotoxin thiab exotoxins.
