Qhov sib txawv tseem ceeb ntawm O thiab H antigen yog O antigen yog qhov sab nraud ntawm cov kab mob saum npoo npog thaum H antigen yog cov qauv sib luag zoo li uas yog ib feem ntawm flagella.
Antigens yog qhov chaw paub txog molecular muaj nyob rau hauv ntau cov kab mob, fungi, kab mob, plua plav thiab lwm yam cellular thiab non-cellular hais uas tuaj yeem lees paub los ntawm tus tswv tsev tiv thaiv kab mob. Feem ntau, feem ntau cov antigens muaj nyob rau ntawm lub cell. Raws li txoj cai, antigens tuaj yeem yog cov protein, amino acids, lipids, glycolipids lossis glycoproteins lossis cov cim nucleic acid. Cov molecules no muaj lub peev xwm tshwj xeeb los ua kom muaj kev tiv thaiv kab mob hauv cov tswv tsev. Qhov kev tiv thaiv kab mob no yog coj los ntawm kev tsim cov tshuaj tiv thaiv kab mob raws li cov txiaj ntsig sib raug.
Antigens feem ntau yog siv rau hauv serotype identification system rau cov kab mob. Salmonella yog ib hom kab mob uas muaj ntau yam serotypes. Serotypes yog pab pawg ntawm cov kab mob hauv tib hom. Cov serotypes no tuaj yeem paub qhov txawv siv kev sib xyaw ntawm O antigen thiab H antigen. O antigen yog LPS sab saw thaum H antigen yog ib feem ntawm flagella.
O Antigen yog dab tsi?
O antigen yog qhov chaw sab nraud ntawm cov kab mob npog npog. Nws yog ib tug somatic antigen. Qhov tseeb, nws yog polysaccharide uas yog ib feem ntawm lub cell phab ntsa lipopolysaccharide. Raws li qhov muaj pes tsawg leeg ntawm oligosaccharides ntawm lipopolysaccharide, O antigens tuaj yeem txiav txim siab hauv txhua qhov serotype.
Daim duab 01: O Antigen
O antigens yog cov cua sov ruaj khov thiab dej cawv tiv taus. Tab sis O antigens yog formaldehyde labile. Ntawm cov kab mob serotypes, O antigen tshwj xeeb yog txiav txim siab los ntawm cov piam thaj ua ntu zus ntawm cov saw hlau polysaccharide.
H Antigen yog dab tsi?
H antigen yog ib feem ntawm flagella. Nws yog cov qauv zoo li cov qauv ntawm flagella. H antigen yog tsim los ntawm flagellin protein. Yog li ntawd, nws yog ib tug proteinaceous antigen. Tsis zoo li O antigen, H antigen tsis yog ib feem ntawm phab ntsa ntawm tes los yog somatic antigen. Nws yog flagellar antigen.
Daim duab 02: H Antigen
H antigens yog cov cua sov-labile thiab rhiab rau cawv. Tab sis lawv yog formaldehyde ruaj khov. H antigens pheej mus ntev, thiab lawv yog cov immunogenic heev.
Dab tsi yog qhov zoo sib xws ntawm O thiab H Antigen?
- Cov kws tshawb fawb siv kev sib xyaw ntawm O thiab H antigens txhawm rau txiav txim siab serotypes.
- Widal test ntsuas cov tshuaj tiv thaiv tiv thaiv H thiab O antigens.
Qhov txawv ntawm O thiab H Antigen yog dab tsi?
O antigens yog cov khoom tseem ceeb ntawm qhov chaw lipopolysaccharide (LPS) ntawm cov kab mob thaum H antigens yog slender threadlike ib feem ntawm flagella ntawm cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm O thiab H antigen. Tsis tas li ntawd, O antigen yog polysaccharide thaum H antigen yog protein.
Ntxiv mus, O antigens yog tsim los ntawm polysaccharides; li no, lawv yog cov cua sov ruaj khov. Tab sis, H antigens yog tsim los ntawm cov protein; yog li ntawd lawv yog tshav kub-labile. Tsis tas li ntawd, O antigens yog cawv-resistant thaum H antigens yog cawv.
Cov duab hauv qab no ntawm qhov sib txawv ntawm O thiab H antigen qhia ntau qhov sib piv ntawm ob qho tib si.
Summary – O vs H Antigen
O antigen thiab H antigen yog ob hom antigens siv los txiav txim siab cov kab mob sib txawv ntawm hom kab mob. O antigen yog lipopolysaccharide pom nyob rau ntawm phab ntsa ntawm tes. H antigen yog ib qho proteinaceous antigen uas yog ib feem ntawm flagella. Yog li, O antigen yog somatic antigen thaum H antigen yog flagellar antigen. Yog li, qhov no qhia txog qhov sib txawv ntawm O thiab H antigen.
