Probiotics tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob pathogenic los ntawm kev tsim cov organic acids, txo cov plab hnyuv pH, sib tw rau cov as-ham, nyob qhov chaw, thiab tsim cov kab mob bacteriocins, tswj cov kab mob hauv plab hnyuv thiab tswj qhov sib npaug ntawm cov hnyuv, yog li ntxiv tswj lub cev tiv thaiv kab mob. cov ntsiab lus raws li hauv qab no:
1. Kev tswj hwm cov txiaj ntsig ntawm probiotics ntawm lub cev tsis muaj zog
Ntxiv dag zog rau cov hnyuv mucosal barrier: Probiotics tsis tuaj yeem tsuas txhawb kev loj hlob ntawm cov kab mob hauv paus hauv cov hnyuv, tab sis kuj inhibit qhov kev loj hlob, adhesion thiab ntxeem tau ntawm cov kab mob pathogenic los ntawm ntau txoj hauv kev, normalize lub cev tsis muaj zog, yog li txhim kho txoj hnyuv biology. barrier muaj nuj nqi. Tib lub sijhawm, probiotics tuaj yeem sib tw nrog cov kab mob tsis zoo rau cov as-ham thiab inhibit lawv txoj kev loj hlob.
Txhim khu kev tiv thaiv kab mob hauv lub cev: Phagocytes suav nrog ntau yam macrophages, monocytes, thiab lwm yam. Txhua hnub noj cov tshuaj probiotics me me tuaj yeem txhim kho cov teebmeem ntawm macrophages thiab lwm yam tshuaj tiv thaiv kab mob.

Ntau cov kev tshawb fawb tau pom tias probiotics tuaj yeem txhawb kev loj hlob ntawm tib neeg sIgA-secreting hlwb, yog li nce qib sIgA. sIgA yog ib qho tseem ceeb heev antibody molecule uas ua lub luag haujlwm txiav txim siab hauv lub cev thawj kab ntawm kev tiv thaiv kab mob. sIgA raug suav hais tias yog lub cev tiv thaiv kab mob ntawm cov mucosal nto. Nws tuaj yeem cuam tshuam qhov adhesion, colonization lossis ntxeem tau ntawm mucosal nto los ntawm cov kab mob. Qhov kev tiv thaiv kab mob no tuaj yeem tiv thaiv kev ncaj ncees ntawm mucosal barrier thiab thaiv cov kab mob ntawm lub cev los ntawm cov kab mob.

4. Probiotics tsim cov kab mob kab mob hauv cov hnyuv
Probiotics adheres rau qhov chaw ntawm lub plab hnyuv mucosa, tsim cov kab mob membrane barrier. Ib tug loj tus naj npawb ntawm cov kab mob probiotics thiab cov kab mob pathogenic txeeb tau txoj hauj lwm thiab cov fermentation substrate nyob rau hauv txoj hnyuv, thiab secrete tshuaj nrog cov kab mob bactericidal kom ncaj qha tshem tawm cov kab mob phem los yog lwm yam tom qab muaj peev xwm adhesion, cov kab mob phem raug tshem tawm ntawm lub cev los ntawm quav thiab lwm txoj kev. , yog li ntawd cov kab mob phem tsis tuaj yeem nyob hauv txoj hnyuv.
