Enterococcus Faecium: Kev siv ntau yam hauv zaub mov, pub, thiab ntau dua

●Dab tsi yog Enterococcus Faecium?

Enterococcus Faecium, ib tug neeg nyob hauv tib neeg thiab tsiaj txhu hauv plab hnyuv, tau ntev tau ua haujlwm hauv kev tshawb fawb microbial raws li ob qho tib si kab mob thiab probiotic. Nws cov yam ntxwv tshwj xeeb ntawm lub cev thiab kev ua haujlwm muaj ntau yam muaj peev xwm ua tau dav dav rau kev siv hauv kev ua liaj ua teb, kev kho mob, thiab kev tswj hwm ib puag ncig, tab sis kev pheej hmoo ntawm kev siv tshuaj tiv thaiv kuj tau ua rau muaj kev tshawb fawb tseem ceeb.

Enterococcus Faecium yog Gram-positive, hydrogen peroxide-negative coccus nrog lub cheeb ntawm 0.5-1.0 microns. Nws tsis muaj cov spores thiab cov tshuaj ntsiav thiab tuaj yeem tsim cov saw luv luv lossis ib qho chaw nyob. Raws li ib tug neeg sawv cev ntawm cov genus Enterococcus, nws yog dav faib nyob rau hauv lub plab zom mov thiab kev ua me nyuam txoj kev ntawm tib neeg thiab tsiaj txhu, raws li zoo raws li nyob rau hauv ib puag ncig, tsim ib tug symbiotic kev sib raug zoo nrog nws tus tswv tsev. Txawm li cas los xij, qee cov kab mob muaj cov kab mob virulence (xws li hemolysins thiab adhesins) uas tuaj yeem ua rau muaj kab mob, ua rau nws yog ib qho tseem ceeb ntawm cov kab mob nosocomial.

●Dab tsi yog CovCov txiaj ntsigNtawm Enterococcus Faecium ?

1. Prebiotic Function

Barrier Kev Tsim Kho: Ua raws li txoj hnyuv epithelium los ua ib qho biofilm, inhibit qhov colonization ntawm Escherichia coli thiab Salmonella, thiab txo qis cov kab mob hauv plab hnyuv.

Immunomodulation: Ua kom cov macrophages, txhawb cov tshuaj tiv thaiv kab mob, thiab txhim kho cov kab mob tiv thaiv kab mob.

Nutrient Metabolism: Sib cais cov proteins rau hauv me me peptides, tsim cov vitamins B, thiab txhawb kev nqus calcium.

2. Pathogenic Mechanism

Tus tswv tsev Protein Hijacking: khi rau tus tswv tsev FABP2 protein ntawm qhov chaw receptor EF3041, ua rau txoj hauv kev nkag siab ntawm pawg ntseeg thiab ua rau plab hnyuv dysbiosis hauv Crohn tus kab mob.

Virulent Expression: Hauv cov tib neeg uas tsis muaj zog tiv thaiv kab mob, tus kab mob no nkag mus rau hauv cov hlab ntsha, zis, thiab lwm yam kabmob, ua rau endocarditis, kab mob urinary, thiab tom qab phais abscesses.

●Dab tsi yog CovDaim ntawv thovOf Enterococcus Faecium?

1. Tsiaj Tsiaj

Pub Additive: Ntxiv 100-200 grams ib tuj los txhim kho plab hnyuv microbiome, txo cov kab mob raws plab, thiab txo cov ammonia nitrogen emissions.

Silage Fermentation: Ua haujlwm sib koom ua ke nrog cellulase los txhim kho kev noj zaub mov zoo thiab muaj txiaj ntsig zoo.

2. Aquaculture

Dej Purification: Siv 50-100 grams ib mu ntawmenterococcus faeciumkom degrade ammonia nitrogen thiab nitrite, inhibiting xiav-ntsuab algae blooms.

Kev Tswj Kab Mob: Inhibits dej kab mob los ntawm secreting antimicrobial peptides, txo cov tshuaj tua kab mob.

3. Kev kho mob

Kev npaj Probiotic: Siv rau hauv qhov chaw mos los yog qhov ncauj npaj los tswj cov kab mob sib npaug (Ceeb toom: Vim muaj kev pheej hmoo ntawm kev siv tshuaj tiv thaiv, qee lub tebchaws txwv tsis pub siv tshuaj kho mob).

Kev Tshawb Fawb Tshuaj Tiv Thaiv: Siv los ua tus qauv kab mob los txheeb xyuas cov txheej txheem sib kis ntawm cov tshuaj tiv thaiv kab mob.

●Kev noj tshuaj thiab kev nyab xeebntawmEnterococcus Faecium

1. Pom zoo noj

Cov tsiaj nyeg thiab nqaij qaib pub: 150 g / tuj thaum lub sij hawm fattening, 200-250 g / ton thaum lub sij hawm weaning, rau 10-15 hnub.

Aquaculture: 0.5 g / m2 rau ib puag ncig kev kho mob, rov ua dua txhua 5-7 hnub hauv thaj chaw muaj kev puas tsuaj loj.

2. Ceev faj

Tsis txhob sib xyaw nrog cov tshuaj tua kab mob lossis dej kub. Khaws rau hauv qhov chaw txias, qhuav.

Daim ntawv thov kev kho mob yuav tsum muaj kev soj ntsuam nruj ntawm cov tshuaj tiv thaiv. Kev sib xyaw nrog cov tshuaj xws li vancomycin raug txwv.
