Tus pab pawg B streptococcal hemolysin zoo li zoo ib yam li, tab sis txawv ntawm, streptolysin streptolysin Streptolysins yog ob hom hemolytic exotoxins los ntawm Streptococcus Hom suav nrog streptolysin O (SLO; slo), uas yog oxygen-labile, thiab streptolysin S (SLS; sagA), uas yog oxygen ruaj khov. SLO yog ib feem ntawm thiol-activated cytolysin tsev neeg. Nws yog hemolytically active tsuas yog nyob rau hauv ib tug reversibly txo lub xeev. https://en.wikipedia.org › wiki › Streptolysin

S tsim los ntawm Streptococcus pyogenes.
Dab tsi yog ob hemolysins tsim los ntawm streptococci?
Beta-hemolytic Streptococci (ua tiav hemolysis)
Beta hemolysis yog tshwm sim los ntawm ob hemolysins O thiab Sqhov hemolysin O yog oxygen lav (tsis ua haujlwm nyob rau hauv muaj. oxygen) thiab hemolysin S yog oxygen ruaj khov cytotoxin.
Qhov twg ntawm ob qhov hemolysins tsim los ntawm streptococci tau qhia thaum lub sijhawm anaerobic?
Muaj ob hom hemolysins hauv Beta hemolysis, hu ua streptolysins. 1. Streptolysin O: Oxygen-labile, qhia txog kev ua haujlwm siab tshaj plaws nyob rau hauv cov xwm txheej anaerobic thiab kev tawg ntawm cov pa oxygen.
Dab tsi enzymes nyob hauv Streptococcus pyogenes?
Streptococcus pyogenes secretes ob tug paub zoo hemolysins, streptolysin O thiab streptolysin S, uas muaj teebmeem rau ntau hom cell.
Cov piv txwv ntawm Exotoxins yog dab tsi?
(Science: protein) cov tshuaj lom uas tso tawm los ntawm cov kab mob gram-positive thiab gram-negative as opposed to endotoxins uas tsim ib feem ntawm lub cell phab ntsa. Piv txwv yog kab mob cholera, pertussis thiab diphtheria co toxins. Feem ntau tshwj xeeb thiab tshuaj lom heev.
