Qhov sib txawv tseem ceeb ntawm virulence thiab pathogenicity yog tias virulence yog hais txog qib ntawm pathogenicity ntawm cov kab mob los ua kab mob thaum pathogenicity yog hais txog lub peev xwm ntawm cov kab mob los ua kab mob.
A kab mob yog kab mob uas muaj peev xwm ua tau kab mob. Yog li, cov kab mob ua rau cov kab mob rau cov nroj tsuag, tsiaj txhu thiab kab, thiab lwm yam. Tus tswv tsev thiab cov kab mob yuav tsum tuaj rau hauv kev txiav txim kom muaj kab mob sib kis. Peb yam tseem ceeb hauv kev sib kis kab mob: kab mob, tus tswv tsev, thiab ib puag ncig yam. Txawm li cas los xij, thaum tsis muaj ib qho ntawm cov xwm txheej no, tus kab mob yuav tsis tshwm sim. Ntxiv mus, tom qab kis kab mob, tej zaum yuav muaj peb yam tshwm sim. Thawj qhov ua tau yog tias cov kab mob tuaj yeem raug tshem tawm los ntawm thawj qhov kev tiv thaiv ntawm tus tswv tsev. Qhov thib ob muaj peev xwm yog cov kab mob nkag mus rau hauv tus tswv tsev thiab ua rau muaj kab mob, thaum qhov tshwm sim thib peb yuav yog qhov sib npaug uas cov kab mob thiab tus tswv tsev yuav nyob ua ke thiab txo qis qhov mob tshwm sim los ntawm cov kab mob. Virulence thiab pathogenicity yog ob nqe lus hais txog kev muaj peev xwm ua rau cov kab mob thiab qib ua rau kab mob.
Dab tsi yog Virulence?
Virulence yog qhov ntsuas ntawm lub peev xwm ua rau muaj kab mob hauv tus tswv tsev. Nws piav qhia txog qhov muaj txiaj ntsig tsis zoo rau tus tswv tsev. Txhawm rau ua kom muaj kab mob, ob yam tseem ceeb yog qhov tseem ceeb: qhov xwm txheej ntawm cov kab mob thiab qhov xwm ntawm tus tswv tsev. Tsis tas li ntawd, kev tsim cov caj ces ntawm cov kab mob thiab tus tswv tsev yog qhov tseem ceeb rau tus kab mob tshwm sim. Cov txheej txheem tiv thaiv hauv cov tswv (xws li kev tiv thaiv kab mob hauv tsiaj lossis phenolic compound hauv cov nroj tsuag) yuav hloov lub peev xwm kis tus kab mob. Txawm li cas los xij, kev mob hnyav heev tuaj yeem ua rau tus tswv tsev tuag, thiab nws cuam tshuam tsis zoo rau kev sib kis tus tswv tsev, uas ua rau muaj kev tiv thaiv kab mob.

Virulence factor yog lub luag haujlwm ua rau muaj kab mob. Virulence yam tuaj yeem yog cov protein coded los ntawm cov noob kab mob. Tej zaum kuj yuav muaj kab mob thiab kab mob.
YPathogenicity yog dab tsi?
Pathogenicity yog lub peev xwm ua rau cov kab mob hauv lub cev. Lub pathogenicity yog ib qho kev ntsuas zoo. Ntxiv mus, nws yog ntsuas los ntawm virulence. Tus kab mob yog qhov tshwm sim ntawm kev sib raug zoo ntawm kev ua phem ntawm tus kab mob thiab kev tiv thaiv ntawm tus tswv tsev. Tsis tas li ntawd, ntau yam ntawm cov kab mob ua rau muaj txiaj ntsig zoo los ua tus kab mob. Cov no yog hu ua virulence factor. Cov yam ntxwv tsis zoo muaj xws li cov co toxins uas tua cov cell cell, enzymes uas ua rau ntawm cov phab ntsa ntawm tes, thiab cov tshuaj uas hloov cov cell loj hlob.

Txhua yam kev phem no tsis ua rau tus tswv tsev ib txhij thaum muaj kab mob. Raws li ib qho piv txwv, nyob rau hauv cov kab mob necrotic, co toxins ua hauj lwm whereas, nyob rau hauv mos rot kab mob, cell phab ntsa digestion enzymes ua hauj lwm. Qhov tseeb tseem ceeb yog tias txhua hom kab mob pathogenic tsis sib npaug hauv kev ua phem. Tus nqi ntawm cov tshuaj phem yuav txawv ntawm hom mus rau hom.
Dab tsi zoo sib xws ntawm Virulence thiab Pathogenicity?
- Virulence thiab pathogenicity yog ob nqe lus uas peb siv sib hloov.
- Ob nqe lus piav qhia lub peev xwm ntawm cov kab mob ua rau kab mob.
- Txawm li cas los xij, pathogenicity nyob ntawm kev ua phem
- Ntxiv mus, virulence thiab pathogenicity muaj kev tswj caj ces sib txawv.
Qhov txawv ntawm Virulence thiab Pathogenicity yog dab tsi?
Virulence hais txog qhov mob hnyav ntawm tus kab mob. Tab sis, pathogenicity yog hais txog lub peev xwm ntawm lub cev los ua cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm virulence thiab pathogenicity. Tsis tas li ntawd, virulence tuaj yeem yog qhov ntsuas qhov ntau thiab zoo thaum pathogenicity yog qhov ntsuas zoo. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm virulence thiab pathogenicity.
Ntxiv mus, kev ua phem tuaj yeem siv los qhia txog qib kev phom sij ntawm cov kab mob. Txawm li cas los xij, pathogenicity tsis tsim nyog los piav qhia txog qib ntawm kev phom sij ntawm cov kab mob. Li no, peb tuaj yeem xav txog qhov no ib yam li qhov sib txawv ntawm kev ua phem thiab kab mob.
Summary – Virulence vs Pathogenicity
Virulence thiab pathogenicity yog ob nqe lus zoo sib xws. Qee zaum, ob lo lus no tau siv sib pauv. Virulence feem ntau yog hais txog tus kab mob tsim lub zog ntawm cov kab mob thaum pathogenicity yog lub peev xwm ntawm lub cev los ua cov kab mob. Zuag qhia tag nrho ob nqe lus piav qhia txog lub peev xwm ua rau muaj kab mob. Tsis tas li ntawd, pathogenicity nyob ntawm cov kab mob virulence xws li enzymes, co toxins, pili, fimbriae, flagella, thiab lwm yam. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm virulence thiab pathogenicity.
