Lub tswv yim ntawm "neutralization cov tshuaj tiv thaiv" uas muaj nyob rau hauv inorganic chemistry txhais tau hais tias cov txheej txheem tshuaj lom neeg uas muaj cov kua qaub thiab cov khoom siv sib cuam tshuam, vim tias cov neeg koom nrog cov tshuaj tiv thaiv poob ob qho tib si thiab lwm yam khoom siv tshuaj lom neeg. Cov tshuaj tiv thaiv neutralization hauv microbiology muaj qhov tseem ceeb thoob ntiaj teb; nws cov khoom poob lawv cov khoom lom. Tab sis, tau kawg, qhov no yog txheej txheem sib txawv kiag li nrog cov neeg koom nrog sib txawv thiab cov txiaj ntsig. Thiab cov cuab yeej lom neeg hauv cov lus nug, uas yog qhov tseem ceeb tshaj plaws rau cov kws kho mob thiab cov kws tshawb fawb, yog lub peev xwm ntawm cov kab mob ua kom muaj kab mob lossis tuag hauv cov tsiaj raug mob.

yog li cas? Qhov kev xeem neutralization yog ib qho kev ntsuam xyuas serological siv hauv kev kuaj mob, uas cov tshuaj tiv thaiv kab mob hauv lub cev tiv thaiv kab mob ua rau cov kab mob, nrog rau cov tshuaj lom thiab lom lom (enzymes) uas lawv tso tawm..

Feem ntau txoj kev tshawb fawb no yog siv los txheeb xyuas cov kab mob, uas yog, txhawm rau txheeb xyuas cov kab mob kis kab mob. Thiab qhov kev xeem tuaj yeem ua tauyog tsom ob qho tib si ntawm kev txheeb xyuas cov kab mob nws tus kheej thiab cov tshuaj tiv thaiv rau nws.

Hauv kab mob bacteriology, cov txheej txheem no feem ntau yog siv los kuaj cov tshuaj tiv thaiv kab mob rau cov kab mob enzymes, xws li antistreptolysins, antistaphylolysins, antistreptokinases.

Yuav ua li cas qhov kev xeem no ua tiav

Cov tshuaj tiv thaiv tsis zoo yog ua raws li lub peev xwm ntawm cov tshuaj tiv thaiv kab mob - cov tshuaj tiv thaiv kab mob tshwj xeeb hauv cov ntshav - kom tsis txhob muaj cov tshuaj tiv thaiv kab mob - cov tshuaj txawv teb chaws uas nkag mus rau hauv lub cev. Yog tias tsim nyog txhawm rau txheeb xyuas cov kab mob thiab txheeb xyuas nws, tom qab ntawd cov txheej txheem tiv thaiv kab mob muaj cov tshuaj tiv thaiv kab mob sib xyaw nrog cov khoom siv roj ntsha. Qhov sib xyaw ua ke tau khaws cia rau hauv qhov ntsuas kub kom haum rau lub sijhawm thiab nkag mus rau hauv qhov chaw txais tos.

Cov no yog cov tsiaj kuaj (nas, nas), qaib embryo, kab lis kev cai ntawm tes. Thaum tsis muaj cov nyhuv lom (kev mob lossis kev tuag ntawm tus tsiaj), nws tuaj yeem txiav txim siab tias qhov no yog tus kab mob uas tus qauv siv tau. Txij li thaum, raws li twb tau hais lawm, ib qho cim qhia tias cov tshuaj tiv thaiv tau dhau los yog kev ploj ntawm bioproperties los ntawm tus kab mob (lub peev xwm ua rau tus tsiaj tuag) vim muaj kev cuam tshuam ntawm cov tshuaj tiv thaiv kab mob ntshav qab zib thiab cov kab mob antigens. Thaum txiav txim siab cov tshuaj lom, cov txheej txheem ntawm kev ua yog tib yam, tab sis muaj cov kev xaiv.

Yog tias ib qho substrate uas muaj cov tshuaj lom, ces nws yog tov nrog standard serum. Nyob rau hauv cov ntaub ntawv ntawm kev kawm tom kawg, ib tug tswj toxic tshuaj yog siv. Txhawm rau kom cov tshuaj tiv thaiv neutralization tshwm sim, qhov sib tov nolub sij hawm predetermined kuj incubated thiab txhaj rau hauv lub cev raug. Cov txheej txheem los ntsuas qhov tshwm sim yog tib yam nkaus.

Hauv kev kho mob thiab kws kho tsiaj, cov tshuaj tiv thaiv kab mob tsis zoo siv los ua kev kuaj mob yog ua tiav hauv cov txheej txheem hu ua khub sera.

Nov yog ib txoj hauv kev kom paub meej tias tus kab mob kis tau tus kab mob. Txhawm rau ua nws, ntshav ntshav tau muab los ntawm tus neeg mob lossis tsiaj ob zaug - thaum pib tus kabmob thiab 14-21 hnub tom qab ntawd.

Yog tias, tom qab kev sim, nce tus naj npawb ntawm cov tshuaj tiv thaiv kab mob rau tus kab mob los ntawm 4 lossis ntau zaus raug kuaj pom, ces qhov kev kuaj mob tuaj yeem txiav txim siab tau lees paub.
