Kev lag luam pub tsiaj txhu tau cuam tshuam tsis tu ncua los ntawm "ob tus kabmob kis" ntawm African swine fever thiab COVID-19, thiab nws tseem tab tom ntsib "ob npaug" kev sib tw ntawm ntau qhov kev nce nqi thiab kev txwv dav.Txawm hais tias txoj kev ua ntej yog tag nrho ntawm cov teeb meem, kev lag luam tsiaj txhu tseem ua haujlwm txhawb nqa nws tus kheej kev hloov pauv thiab hloov kho dua tshiab thiab sib koom ua ke txhawb txoj kev loj hlob ntawm kev lag luam.Daim ntawv no tsuas yog tham txog yuav ua li cas txhawm rau txhim kho cov haujlwm ntawm digestive enzymes nyob rau hauv cov nqaij qaib txoj hnyuv, txhawb txoj hnyuv loj hlob thiab txhim kho cov qauv ntawm cov hnyuv.

Lub plab hnyuv yog ib qho tseem ceeb ntawm cov nqaij qaib kom zom thiab nqus cov as-ham.Lub plab zom mov feem ntau yog ua los ntawm cov tshuaj tiv thaiv enzymatic (exopeptidase, oligosaccharide enzyme, lipase, thiab lwm yam);Cov khoom noj khoom haus me me uas tsim los ntawm cov tshuaj tiv thaiv enzymatic dhau los ntawm txoj hnyuv epithelial txheej thiab tau nqus los ntawm cov hnyuv.

Cov hnyuv kuj yog ib qho kev thaiv ntuj los tiv thaiv cov nqaij qaib los ntawm cov zaub mov antigens, cov kab mob pathogenic thiab lawv cov teeb meem metabolites, thiab tswj kev ruaj ntseg ntawm ib puag ncig sab hauv.Cov kab mob plab hnyuv muaj cov khoom thaiv, tshuaj tiv thaiv kab mob, microbial barrier thiab tiv thaiv kab mob sib koom ua ke tiv thaiv kev cuam tshuam ntawm txawv teb chaws antigenic tshuaj.Mechanical barrier (lub cev barrier) yog hais txog kev ua kom tiav cov plab hnyuv epithelial sib txuas nrog ib leeg;Tshuaj thaiv kab mob yog tsim los ntawm mucus, digestive kua txiv secreted los ntawm txoj hnyuv mucosal epithelial hlwb thiab cov tshuaj tua kab mob uas ua los ntawm cov kab mob plab hnyuv parasitic, uas tuaj yeem inhibit lossis tua cov kab mob pathogenic;Cov kab mob lom yog tsim los ntawm kev colonization tsis kam ntawm cov kab mob hauv plab hnyuv mus rau cov kab mob pathogenic thiab cov tsub zuj zuj ntawm cov kab mob;Lub cev tiv thaiv kab mob yog qhov loj tshaj plaws lymphoid lub cev thiab tseem ceeb mucosa ntsig txog cov ntaub so ntswg lymphoid.Yog li ntawd, kev yug me nyuam yog txhawb txoj hnyuv, thiab ua kom txoj hnyuv noj qab haus huv yog tus yuam sij rau kev noj qab haus huv yug me nyuam yam tsis muaj kev tiv thaiv.

Acid muaj cov teebmeem ntawm acidification thiab bacteriostasis, thiab plays lub luag haujlwm tseem ceeb hauv kev noj qab haus huv nqaij qaib.Cov organic acids muaj xws li yooj yim carboxylic acids (formic acid, acetic acid, propionic acid thiab butyric acid), carboxylic acids uas muaj hydroxyl pawg (lactic acid, malic acid, tartaric acid thiab citric acid), luv saw carboxylic acids uas muaj ob daim ntawv cog lus (fumaric acid). thiab sorbic acid) thiab inorganic acids (phosphoric acid) (sh Khan thiab j Iqbal, 2016).Cov acidification thiab bacteriostatic muaj peev xwm ntawm ntau cov kua qaub sib txawv, piv txwv li, formic acid muaj peev xwm bacteriostatic tshaj plaws;Ntawm cov kua qaub rau ib chav tsev hnyav, formic acid muaj qhov muaj zog tshaj plaws hydrogen muab peev xwm;Propionic acid thiab formic acid muaj zog tiv thaiv mildew nyhuv.Yog li ntawd, thaum xaiv cov kua qaub, nws yuav tsum tau scientific proportioned raws li cov khoom ntawm acid.Ntau qhov kev tshawb fawb tau pom tias ntxiv cov kua qaub rau kev noj zaub mov tuaj yeem txhim kho thiab txhawb txoj hnyuv, txhim kho cov kev ua haujlwm ntawm plab hnyuv plab enzymes, txhim kho cov qauv ntawm cov hnyuv, thiab pab kev noj qab haus huv yug me nyuam yam tsis muaj cov khoom noj Japanese.

Hauv kev xaus, kev npaj kua qaub muaj txiaj ntsig tseem ceeb hauv kev ua kom txoj hnyuv noj qab haus huv ntawm cov nqaij qaib.Thaum ua ntawv thov thiab xaiv cov kua qaub, yuav tsum tau them nyiaj mloog mus rau qhov muaj pes tsawg leeg, kev faib ua feem, cov ntsiab lus thiab cov txheej txheem ntawm acid npaj kom muaj kev nyab xeeb, ruaj khov thiab muaj txiaj ntsig ntawm cov khoom.
