Antigens yog cov lwg me me muaj peev xwm txhawb kev tiv thaiv kab mob. Txhua tus antigen muaj cov yam ntxwv sib txawv, lossis epitopes, ua rau muaj cov lus teb tshwj xeeb. Antibodies (immunoglobins) yog cov protein zoo li Y tsim los ntawm B cells ntawm lub cev tiv thaiv kab mob los teb rau kis antigens.
Ua kom pom qhov no, antigens thiab tshuaj tiv thaiv kab mob hauv ntshav yog dab tsi?
Antigens Thiab Antibodies . Antibodies yog hom tshwj xeeb ntawm cov kab mob tiv thaiv kab mob tiv thaiv kab mob hu ua immunoglobulins, uas nws lub luag haujlwm yog los tua cov kab mob los ntawm kev khi lawv tus kheej rau antigens . Nyob rau hauv rooj plaub ntawm ABO ntshav group, cov antigens muaj nyob rau saum npoo liab ntshav cell, thaum lub tshuaj tiv thaiv nyob hauv cov ntshav.
Kuj Paub, 3 yam antigens yog dab tsi? Muaj peb hom antigen nthuav tawm cov cell hauv lub cev: macrophages, dendritic cells thiab В cells.
- Macrophages: Macrophages feem ntau pom muaj nyob hauv lub xeev so.
- Dendritic Cells: Cov hlwb no yog tus cwj pwm los ntawm cov txheej txheem cytoplasmic ntev.
- B-hlwb:
Ntawm no, qhov twg muaj cov tshuaj tiv thaiv kab mob thiab antigens pom?
Cov antigen -binding site ntawm tshuaj tiv thaiv kab mob npe hu ua paratope nyob ntawm cov lus qhia ntawm "Y" thiab xauv mus rau qhov chaw sib ntxiv ntawm lub antigen npe epitope. Qhov kev hloov pauv siab ntawm paratope tso cai rau lub cev tiv thaiv kab mob kom paub txog ntau yam sib npaug antigens.
Puas yog antigens tsis zoo?
Lub cev tiv thaiv kab mob tiv thaiv lub cev los ntawm cov tshuaj muaj kuab lom los ntawm kev lees paub thiab teb rau antigens . Antigens yog cov tshuaj (feem ntau yog cov protein) nyob saum cov cell, kab mob, kab mob, lossis kab mob. Koj lub cev tiv thaiv kab mob kawm paub pom cov no antigens zoo li qub thiab feem ntau tsis hnov lus tawm tsam lawv.

Dab tsi yog txhais los ntawm kev tiv thaiv kab mob tiv thaiv kab mob?
Kev tshuaj tiv thaiv kab mob tiv thaiv kab mob tau siv los txiav txim siab tias cov tshuaj tua kab mob tshwj xeeb tshwj xeeb cov kab mob tshwj xeeb lossis kab mob hu ua fungus. Feem ntau, qhov kev sim no ua tiav Gram Stain thiab kab lis kev cai, cov txiaj ntsig uas tau txais sai dua
Kev tiv thaiv kab mob thiab kev tiv thaiv kab mob yog dab tsi?
Lub cev tiv thaiv kab mob yog lub network nyuaj ntawm cov cell thiab cov protein uas tiv thaiv lub cev tiv thaiv kab mob. Lub cev tiv thaiv kab mob khaws cov ntaub ntawv ntawm txhua tus kab mob (microbe) nws tau swb lawm yog li nws tuaj yeem lees paub thiab rhuav tshem cov kab mob sai sai yog tias nws nkag mus rau hauv lub cev dua
Agar yog dab tsi siv rau kev sim tshuaj tiv thaiv kab mob tiv thaiv kab mob?
Müeller-Hinton agar nquag siv hauv qhov tshuaj tiv thaiv kab mob tiv thaiv kab mob no
Dab tsi yog qhov tshuaj tiv thaiv kab mob tiv thaiv kab mob tam sim?
Cov tshuaj tiv thaiv kev hloov pauv tau txhais tias yog cov xwm txheej tsis zoo cuam tshuam nrog kev tso ntshav tag nrho lossis ib qho ntawm nws cov khoom. Cov tshuaj tiv thaiv tuaj yeem tshwm sim thaum lub sijhawm tso ntshav (mob ntshav tawm tsam) lossis hnub mus rau lub lis piam tom qab (kev hloov pauv tsis tu ncua) thiab tej zaum yuav yog immunologic lossis non-immunologic
Cov tshuaj tiv thaiv ua haujlwm li cas lawv ua haujlwm tiv thaiv kab mob thiab kab mob?
Cov tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Txhawm rau ua qhov no, qee cov molecules los ntawm cov kab mob yuav tsum tau nkag rau hauv lub cev kom ua rau muaj kev tiv thaiv kab mob. Cov molecules no hu ua antigens, thiab lawv muaj nyob rau tag nrho cov kab mob thiab cov kab mob
