Kev sib xyaw thiab cuam tshuam rau ntawm daim tawv nqaij Microbes

Cov Txheej Txheem thiab cuam tshuam ntawmDaim tawv nqaij Microbes

1. Muaj pes tsawg leeg ntawm daim tawv nqaij microbes

Cov kab mob ntawm daim tawv nqaij yog cov tswv cuab tseem ceeb ntawm daim tawv nqaij ecosystem, thiab cov nroj tsuag ntawm daim tawv nqaij feem ntau tuaj yeem muab faib ua cov kab mob nyob hauv cov kab mob thiab cov kab mob mus sij hawm ntev. Cov kab mob nyob hauv yog ib pawg ntawm cov kab mob uas ua rau cov tawv nqaij noj qab haus huv, suav nrog Staphylococcus, Corynebacterium, Propionibacterium, Acinetobacter, Malassezia, Micrococcus, Enterobacter, thiab Klebsiella. Cov kab mob ib ntus xa mus rau ib chav kawm ntawm cov kab mob uas tau txais los ntawm kev sib cuag nrog ib puag ncig sab nraud, suav nrog Staphylococcus aureus, Streptococcus hemolyticus thiab Enterococcus, thiab lwm yam. Lawv yog cov kab mob tseem ceeb uas ua rau muaj kab mob ntawm daim tawv nqaij. Cov kab mob yog cov kab mob loj tshaj plaws ntawm daim tawv nqaij, thiab tseem muaj cov kab mob ntawm daim tawv nqaij. Los ntawm phylum theem, cov yeeb yam tshiab ntawm daim tawv nqaij yog tsim los ntawm plaub phyla, uas yog Actinobacteria, Firmicutes, Proteobacteria thiab Bacteroidetes. Los ntawm qib genus, cov kab mob ntawm daim tawv nqaij feem ntau yog Corynebacterium, Staphylococcus thiab Propionibacterium. Cov kab mob no ua lub luag haujlwm tseem ceeb hauv kev noj qab haus huv ntawm daim tawv nqaij.

2. Yam cuam tshuam rau daim tawv nqaij microecology

(1) Host factor

Xws li hnub nyoog, poj niam txiv neej, qhov chaw, tag nrho cov cuam tshuam rau ntawm daim tawv nqaij microbes.

(2) daim tawv nqaij appendages

Invaginations thiab appendages ntawm daim tawv nqaij, nrog rau cov qog hws (hws thiab apocrine qog), qog sebaceous, thiab cov hauv paus plaub hau, muaj lawv tus kheej flora.

(3) Topography ntawm daim tawv nqaij nto.

Topographical kev hloov ntawm daim tawv nqaij nto yog nyob rau hauv lub regional sib txawv ntawm daim tawv nqaij anatomy. Kab lis kev cai raws li txoj kev kawm hais tias cov cheeb tsam txawv teb chaws txhawb nqa cov kab mob sib txawv.

(4) Lub cev qhov chaw

Molecular biological txoj kev tshawb pom lub tswv yim ntawm cov kab mob sib txawv, hais txog tias daim tawv nqaij microbiota yog lub cev nyob ntawm qhov chaw. Cov kab mob colonization yog nyob ntawm qhov chaw physiological ntawm daim tawv nqaij thiab yog txuam nrog ib qho tshwj xeeb moist, qhuav, sebaceous microenvironment, thiab lwm yam.

(5) Lub sijhawm hloov pauv

Cov txheej txheem molecular biological tau siv los kawm txog kev hloov pauv ntawm lub cev thiab qhov chaw ntawm daim tawv nqaij microbiota, uas tau pom tias muaj feem cuam tshuam nrog lub sijhawm thiab qhov chaw ntawm kev kuaj.

(6) pH hloov

Thaum ntxov li xyoo 1929, Marchionini tau ua pov thawj tias daim tawv nqaij yog acidic, yog li tsim lub tswv yim tias daim tawv nqaij muaj "lub tsho tiv no" uas tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab tiv thaiv lub cev los ntawm kev kis kab mob, uas tau siv hauv kev tshawb fawb dermatological rau niaj hnub no.

(7) Exogenous yam - kev siv tshuaj pleev ib ce

Muaj ntau yam exogenous yam cuam tshuam raudaim tawv nqaij microecology, xws li kub, av noo, huab cua zoo, tshuaj pleev ib ce, thiab lwm yam ntawm ib puag ncig sab nraud. Ntawm ntau yam sab nraud, tshuaj pleev ib ce yog ib qho tseem ceeb cuam tshuam rau ntawm daim tawv nqaij microecology hauv qee qhov ntawm tib neeg lub cev vim kev sib cuag ntawm daim tawv nqaij nrog tshuaj pleev ib ce.
