Qhov Tseem Ceeb - Endotoxin vs Enterotoxin
A toxin yog ib yam tshuaj lom uas yog tsim los ntawm ib lub cell los yog kab mob. Cov tshuaj lom yog tsim los ntawm ntau hom kab mob xws li kab mob, fungi, nroj tsuag, thiab tsiaj txhu. Cov kab mob yog cov kab mob uas paub zoo uas tsim cov co toxins uas ua rau muaj kab mob loj xws li kab mob tetanus, cholera, thiab diphtheria. Cov kab mob tsim ob hom co toxins hu ua endotoxins thiab exotoxins. Endotoxins nyob rau hauv cov kab mob ntawm cov kab mob. Lawv ua haujlwm ua ib feem ntawm cov kab mob ntawm cov phab ntsa ntawm cov kab mob thiab ua los ntawm lipids. Endotoxins raug tso tawm sab nraud thaum cov kab mob ntawm tes yog lyzed. Exotoxins yog cov kab mob lom uas tsim los ntawm cov kab mob. Lawv raug tsim thiab tso tawm sab nraum cov kab mob hlwb. Enterotoxin yog ib hom exotoxin uas tso tawm rau hauv cov hnyuv ntawm cov kab mob. Cov enterotoxins no yog tsim los ntawm qee hom kab mob thiab ua rau cov zaub mov lom thiab ntau yam kab mob hauv plab. Qhov sib txawv tseem ceeb ntawm endotoxin thiab enterotoxin yog tias endotoxin yog cov tshuaj lom uas tsim nyob rau hauv cov kab mob ntawm tes thaum enterotoxin yog cov tshuaj lom uas tsim los rau hauv cov hnyuv los ntawm cov kab mob.
Endotoxin yog dab tsi?
Endotoxin yog ib yam tshuaj lom uas muaj nyob rau hauv cov kab mob ntawm tes uas tawm thaum cov kab mob ntawm tes tawg. Lawv yog lipopolysaccharides uas nyob rau hauv daim nyias nyias ntawm cov kab mob gram-tsis zoo. Cov txheej membrane yog tshwj xeeb rau cov kab mob gram-negative. Yog li, endotoxins ib txwm cuam tshuam nrog cov kab mob gram-tsis zoo. Qee hom kab mob gram-tsis zoo xws li Escherichia coli, Salmonella, Shigella, Pseudomonas, Neisseria, Haemophilus influenza, Bordetella pertussis thiab Vibrio cholera yog cov paub zoo endotoxin tsim.
Endotoxin muaj peb yam hauv nws cov qauv: lipid A, O antigen (O polysaccharide) thiab polysaccharide. Toxicity feem ntau cuam tshuam nrog lipid A tivthaiv thiab cov xwm txheej antigenic cuam tshuam nrog O antigen. Endotoxins tsis ua enzymatically. Lawv kuj tsis nquag soluble. Txawm li cas los xij, endotoxins yog cov cua sov ruaj khov thiab tsis tuaj yeem rhuav tshem los ntawm boiling. Qee cov tshuaj oxidizing muaj zog xws li superoxide, peroxide, thiab hypochlorite tuaj yeem siv los rhuav tshem cov tshuaj endotoxins.
Daim duab 01: Endotoxins lossis lipopolysaccharides hauv Gram-negative Bacteria
Endotoxins tsis raug tso tawm rau sab nraud kom txog thaum lub cell raug autolysis, sab nraud lysis lossis phagocytic digestion. Lawv nyob twj ywm ua ib feem ntawm cov txheej membrane ntawm cov kab mob.
Enterotoxin yog dab tsi?
Ib qho enterotoxin yog cov protein exotoxin tso tawm los ntawm cov kab mob uas ua rau cov hnyuv. Enterotoxins yog tsim nyob rau hauv los yog tso rau hauv cov hnyuv. Qee hom kab mob muaj peev xwm tsim cov enterotoxins. Enterotoxins nyob rau hauv qeb ntawm exotoxin. Lawv yog cov proteins thiab tuaj yeem ua cov enzymes. Enterotoxins yog cov pore-forming co toxins. Yog li ntawd, lawv tsim pores nyob rau hauv lub epithelial hlwb ntawm txoj hnyuv. Thaum cov enterotoxins nce permeability rau chloride ions nyob rau hauv cov hnyuv mucosal hlwb, nws ua rau secretory raws plab. Staphylococcus aureus thiab E. coli yog ob hom kab mob uas tuaj yeem tsim cov kab mob xws li enterotoxins.
Daim duab 02: Kev Ua ntawm Anthrax Exotoxins
Feem ntau, enterotoxins yog tsim los ntawm cov kab mob gram-zoo. Txawm li cas los xij, qee cov kab mob gram tsis zoo tuaj yeem tsim cov enterotoxins. Piv txwv li, Vebrio tus kab mob cholera yog ib tus paub zoo enterotoxin tsim thiab yog kab mob gram-negative.
Dab tsi zoo sib xws ntawm Endotoxin thiab Enterotoxin?
- Endotoxins thiab enterotoxins yog tsim los ntawm cov kab mob pathogenic.
- Endotoxins thiab enterotoxins yog tshuaj lom.
