Spore - tsim cov kab mob xws li Bacillus (aerobic) thiab Clostridium (anaerobic) hom. Cov kab mob ntawm cov hom no yog cov dormant lub cev uas nqa tag nrho cov genetic khoom raws li pom nyob rau hauv cov vegetative daim ntawv , tab sis tsis muaj cov metabolism hauv nquag.
Ib yam li ib tus tuaj yeem nug, dab tsi yog spore tsim cov kab mob muaj peev xwm?
Nyob ntawm seb hom twg kab mob , kab mob tau muab faib ua endospores, exospores, myxospores, thiab cysts. Tshwj xeeb tshaj yog endospores yog tus yam ntxwv los ntawm ib tug complex qauv thiab tsis kam mus rau high kub. Yog vim li cas qhov no dormant daim ntawv yog muaj peev xwm ntawm kev muaj sia nyob rau lub sijhawm ntev dua ntau txhiab xyoo.
Ib tug kuj yuav nug, vim li cas cov kab mob ua rau cov kab mob txaus ntshai? Raws li kab mob , kab mob tuaj yeem nyob twj ywm rau ntau xyoo, tiv thaiv los ntawm kev ntxhov siab xws li raws li tshuaj, cua sov, hluav taws xob thiab lub cev qhuav dej. Thaum rov ua dua, txawm li cas los xij, cov no kab mob tuaj yeem ua rau muaj tus kab mob ntau ntxiv, suav nrog botulism, anthrax, tetanus thiab cov zaub mov lom lom.
Kuj tseem paub, dab tsi yog kab mob spores?
Cov kab mob spores muaj kev tiv taus zoo, tsis muaj cov txheej txheem (piv txwv li tsis muaj cov txheej txheem metabolic) tsim los teb rau cov xwm txheej tsis zoo. Lawv pab kom muaj sia nyob ntawm cov kab mob thaum lub sij hawm tsis zoo ib puag ncig; lawv tsis muaj lub luag haujlwm hauv kev luam tawm.
Koj ua li cas tua cov kab mob sib kis?
Tshuaj tua kab mob ua tau tua cov kab mob , tab sis lawv tsis ua rhuav tshem lawv kab mob . Cov txheej txheem hu ua sterilization rhuav tshem spores thiab kab mob . Nws ua tiav ntawm qhov kub thiab txias hauv siab. Hauv cov chaw kho mob, kev ua kom tsis muaj menyuam feem ntau yog ua los ntawm kev siv lub tshuab hu ua autoclave.

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?
Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws
Nyob rau theem dab tsi ntawm kev tsim cov kab mob fungal yog diploid cells tsim?
Hauv lub neej voj voog ntawm kev sib deev kis tus kab mob hu ua fungus, theem haploid hloov nrog qib diploid. The haploid theem xaus nrog nuclear fusion, thiab theem diploid pib nrog kev tsim zygote (diploid cell ua los ntawm fusion ntawm ob haploid cells)
Cov kab mob hauv qhov ncauj dab tsi metabolize sucrose tsim cov nplaum glucans thiab tsim cov quav hniav?
GTF yog qhov tseem ceeb enzyme uas catalyzes sucrose rau nplaum glucans thiab pab txhawb kev tsim cov hniav plaque nyob rau hauv uas lub tsub zuj zuj ntawm metabolic acids uas ua los ntawm cov kab mob colonies ua rau lub zos demineralization ntawm cov enamel nto (Loesche, 1986)
Dab tsi yog cov kab mob thiab cov kab mob uas cuam tshuam rau cov kab mob integumentary?
Cov pob txuv cuam tshuam nrog qhov txhaws ntawm qhov pores, uas tuaj yeem ua rau muaj kab mob thiab mob, thiab feem ntau pom hauv cov tub ntxhais hluas. Lwm yam kab mob, tsis tau tham txog ntawm no, suav nrog seborrheic dermatitis (ntawm tawv taub hau), psoriasis, mob khaub thuas, impetigo, kab mob khaus, khaus khaus, thiab pob tw
