Kev Sib Tw Hauv Kev Ua Tau Zoo Tshaj Plaws Thaum Ntxov

Vim li cas thiaj ua tiav kev thauj mus los biosecurity nyuaj heev? Hauv tsab xov xwm no, peb yuav qhia txog ntau yam kev sib tw uas yuav tsum tau kov yeej kom ua tiav biosecurity siab dua hauv kev thauj cov tsheb rau npua.

Kev ntim tshuaj lom neeg lossis kev cais tawm yog qhov tseem ceeb rau biosecurity. Lub hom phiaj ntawm cov kev ntsuas no yog txhawm rau tiv thaiv qhov muaj peev xwm kis tau tus kab mob thiab tswj kev kis tus kab mob sai li sai tau, nce mus txog qib ntawm cov ntaub ntawv qhia. Hauv kev tsim cov npua npua, ib qho ntawm cov kab mob kis tau zoo tshaj plaws yog kev thauj mus los. Kev thauj mus los ntawm npua teb suav nrog kev txav ntawm cov neeg ua haujlwm, thauj khoom noj, thiab thauj tsiaj. Hauv tsab xov xwm no, peb yuav piav qhia txog cov kev sib tw sib txawv uas yuav tsum tau kov yeej kom ua tiav biosecurity siab dua hauv cov tsheb thauj npua.

Thawj qhov kev sib tw hauv kev ua kom tiav qhov chaw huv si yog qhov muaj biofilms. Biofilms yog tsim los ntawm extracellular polymers thiab microbial secretions, accumulating rau inert nto. Qhov no feem ntau tshwm sim nyob rau hauv cov tsiaj tsim ib puag ncig uas cov secretions accumulates nyob rau hauv lub sij hawm thiab tuaj yeem phem zuj zus vim yog hom organic teeb meem thiab cov zaub mov hauv dej. Biofilms ua raws li cov cuab yeej cuab tam, txo cov txiaj ntsig ntawm cov tshuaj tua kab mob. Acidic detergents tuaj yeem nkag mus rau biofilms, txhim kho kev ua tau zoo ntawm cov tshuaj tua kab mob, thiab nws yog qhov tseem ceeb kom tshem tawm cov nplai thiab biofilms los ntawm qhov chaw ua ntej tshuaj tua kab mob.

Qhov kev sib tw thib ob yog cov organic teeb meem, uas ua ke nrog biofilms tuaj yeem ua lub substrate rau kev loj hlob ntawm cov kab mob thiab microbial. Cov khoom seem ntawm cov organic tuaj yeem sib sau ua ke ntawm cov pob khawm thiab cov ces kaum ntawm cov cuab yeej thiab tsheb, ua rau lub caij ntuj no hnyav dua nrog cov khoom seem ntawm cov dej khov, uas tuaj yeem nqa ntau txhiab tus kab mob xws li porcine reproductive thiab ua pa syndrome, porcine epidemic diarrhea virus, thiab African swine fever virus, uas yog heev resistant rau tsawg kub. Kev sib sau ntawm biofilms yog qhov tseem ceeb uas txwv tsis pub siv tshuaj tua kab mob. Microbes siv cov biofilms los tiv thaiv cov ntaub thaiv npog, txuas ntxiv mus nyob ntawm qhov chaw thiab cuam tshuam rau npua teb.

Qhov kev sib tw thib peb yog hais txog qhov porosity ntawm qhov chaw yuav tsum tau ntxuav. Qhov zoo tshaj plaws, cov khoom thauj tsheb yuav tsum yog cov hlau tsis muaj steel; aluminium kuj yooj yim ntxuav. Ntoo lossis cov ntaub ntawv ntxeem tau zoo sib xws ua rau muaj kev nyuaj rau tshem tawm cov organic thiab biofilms. Qhov chaw uas tsis yog ntxeem tau yooj yim dua los ntxuav. Thaum ntxuav qhov chaw nrog ntau qhov pores, kev ua haujlwm thiab / lossis lub siab yuav tsum tso cai rau cov tshuaj ntxuav kom nkag mus rau saum npoo.

Qhov kev sib tw thib plaub yog dej zoo thiab nws cov ntsiab lus tshuaj thiab microbial. Cov ntxhia hauv cov ntsiab lus siab xws li manganese, hlau, calcium, thiab pH ntau, nrog rau cov ntsev ntsev, tuaj yeem cuam tshuam tsis zoo rau cov tshuaj tua kab mob thiab ua raws li cov kab mob substrate. Cov dej tawv txhawb kev tsim cov nplai, ua kom pom tseeb dua nrog kev hloov pauv ntawm cov xim ntawm txhuas qhov chaw. Nyob rau hauv ib puag ncig uas muaj hlau, manganese, thiab cov ntxhia hauv cov ntsiab lus, qee cov kab mob muaj kev vam meej, pab lawv nyob ruaj khov ntawm qhov chaw, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog cov pore zoo.

Qhov kev sib tw thib tsib suav nrog kev teem sijhawm thiab kev thauj mus los hauv kev tsim khoom. Qhov no ua rau muaj kev sib tw tseem ceeb rau kev tu lub tsheb. Kev ua haujlwm tsis raug cai tuaj yeem sib tshooj kev tu kom qhuav (thawj kauj ruam hauv kev tshem tawm cov organic teeb meem) nrog rau lub sijhawm ntawm kev tu dej siab, uas muaj feem cuam tshuam rau lwm qhov chaw vim yog tsim cov organic aerosols. Nto yuav tsum tau qhuav ua ntej siv cov tshuaj tua kab mob, uas tej zaum yuav tsis raug raws sijhawm. Thaum kawg, tom qab siv tshuaj tua kab mob, cov tsheb thauj khoom tuaj yeem tawm ntawm npua teb yam tsis tau ziab tag nrho, tshwj xeeb tshaj yog nyob rau hauv cov nag los nag hnyav heev tuaj yeem dilute los yog ntxuav cov tshuaj tua kab mob.

Qhov thib rau kev sib tw yog kev sib xws; Kev ua tau zoo thiab kev saib xyuas cov khoom siv tu: dej siab thiab cov cua sov. Puas yog cov khoom siv thiab cov khoom siv raug siv? Puas yog dej siab txaus? Puas yog qhov kub thiab txias? Puas yog ua npuas dej ua tiav? Kev ntsuam xyuas thiab kho qhov kev pab cuam thiab dilution yog tsim nyog thaum xav tau. Ntxiv nrog rau kev siv cov khoom kom raug, cov khoom siv tu kom tsim nyog thiab muaj txiaj ntsig yog qhov tseem ceeb.
