Hauv ntau qhov chaw sib txawv ntawm microbiology, lub muaj peev xwm txheeb xyuas tau muaj cov kab mob me me tseem ceeb daim ntawv thov. Piv txwv li, hauv zaub mov microbiology nws yog tseem ceeb kom muaj peev xwm kom raug txheeb xyuas zaub mov spoilage contaminants. Hauv microbial ecology, lub kev qhia kom paub ntawm cov kab mob me me pab peb ua tus yam ntxwv ntawm biodiversity.
Hais txog qhov no, vim li cas nws tseem ceeb rau kev cais thiab txheeb xyuas cov kab mob?
Microbiologists yuav tsum txheeb xyuas cov kab mob cais tawm rau ntau qhov laj thawj: • Kev kuaj mob - qhia paub ib hom kab mob nyob ib leeg los ntawm tus neeg mob. Khoom noj khoom haus kev lag luam - qhia paub ib tug microbial kab mob uas muaj feem xyuam rau cov zaub mov spoilage. Kev tshawb nrhiav chaw - qhia paub ib new cais uas ua raws li tus txheej txheem impor tant.
Tom qab ntawd, lo lus nug yog, vim li cas kev txheeb xyuas qhov tseem ceeb? Raws li tau hais tseg hauv Kev Taw Qhia, qhov tseeb kev qhia kom paub ntawm cov kab mob yog tseem ceeb thaum ntsuas biodiversity ntawm ib cheeb tsam. Thiab tsis muaj tseeb kev qhia kom paub Nws tsis tuaj yeem txiav txim siab seb muaj pes tsawg hom muaj nyob hauv ib cheeb tsam. Qhia paub Cov kab mob yog, txawm li cas los xij, ib txoj haujlwm fraught nrog teeb meem.
Xav txog qhov no, koj yuav txheeb xyuas cov kab mob li cas?
Ntsiab Lus
- Kab mob ua rau muaj kab mob hauv nws tus tswv tsev.
- Thaum txheeb xyuas cov kab mob hauv chav kuaj, cov yam ntxwv hauv qab no yog siv: Gram staining, zoo li, muaj cov tshuaj ntsiav, kev sib koom ua ke, kev txav, kev ua pa, kev loj hlob nruab nrab, thiab seb nws yog intra- lossis extracellular.
Dab tsi yog qhov tseem ceeb ntawm kev kuaj biochemical hauv kev txheeb xyuas cov kab mob?
Kev kuaj ntshav biochemical yog cov kev xeem siv rau kev qhia kom paub ntawm kab mob hom raws li qhov sib txawv ntawm cov biochemical kev ua ub no txawv kab mob . QHOV TSEEB: Kab mob physiology txawv ntawm ib hom mus rau lwm yam.

Vim li cas nws thiaj tseem ceeb rau tus kws saib xyuas neeg mob saib xyuas cov phaj thiab cov tais zaub mov thaum cov neeg nyob hauv tau noj mov tas lawm?
Vim li cas nws thiaj tseem ceeb rau tus kws saib xyuas neeg mob saib xyuas cov phaj thiab cov tais zaub mov thaum cov neeg nyob hauv tau noj mov tas lawm? Nws pab txheeb xyuas qhov kev hloov pauv ntawm cov neeg nyob hauv kev nyiam zaub mov. Tus kws saib xyuas mob nkeeg yuav tsum txheeb xyuas cov zaub mov thiab dej ua ntej cov neeg nyob hauv
Dab tsi ua kom muaj peev xwm ntawm cov kab mob pathogenic ua rau muaj kab mob?
Cov kab mob virulence pab cov kab mob kom (1) nkag mus rau tus tswv tsev, (2) ua rau muaj kab mob, thiab (3) zam tus tswv tsev tiv thaiv. Exotoxins: Exotoxins suav nrog ntau hom kab mob protein thiab cov enzymes tsim thiab/lossis zais los ntawm cov kab mob pathogenic. Cov pawg loj suav nrog cytotoxins, neurotoxins, thiab enterotoxins
Vim li cas cov sinuses thiaj li muaj peev xwm kis tau tus kab mob lub cev?
Zoo li lub qhov ntswg kab noj hniav, cov sinuses tau kab nrog cov hnoos qeev. Cov hnoos qeev tso tawm hauv cov sinuses tau txuas ntxiv mus rau hauv lub qhov ntswg los ntawm cov plaub hau zoo li cov qauv ntawm cov nplaim pa. Qhov no ua haujlwm kom ua kom huab cua ntub peb nqus los ntawm peb lub qhov ntswg. Cov sinuses raug rau kis mob
Vim li cas nws thiaj tseem ceeb kom paub txog lub ntsws thiab lub peev xwm?
Vim Li Cas Lub Peev Xwm Muaj Peev Xwm Tseem Ceeb? Lub ntsws muaj peev xwm kwv yees kev noj qab haus huv thiab kev nyob ntev. Qhov no txhais tau tias koj muaj hnub nyoog laus dua, nws nyuaj rau koj lub ntsws ua pa thiab tuav huab cua. Thaum peb nqus pa tsawg dua, peb lub cev thiab cov hlwb tseem tau txais cov pa oxygen tsawg dua, yuam peb lub siab ua haujlwm nyuaj kom nqus cov pa thoob plaws lub cev
Vim li cas thiaj yuav tsum tau siv kab lis kev cai dawb huv los tshuaj xyuas kab mob ua kom muaj zog tiv thaiv kab mob?
Kev raug cai txhais tau tias tsis tiv taus cov kab mob me me, tab sis yooj yim nkag siab rau cov kab mob me me lossis lwm tus neeg sawv cev. Kev coj noj coj ua dawb huv yog siv rau kev sim tshuaj tiv thaiv kab mob vim hais tias kev coj noj coj ua dawb huv yuav muab ntsuas kom raug dua ntawm cov tshuaj tua kab mob cuam tshuam qhov ua rau muaj kab mob me me
