Cov muaj pes tsawg leeg thiab cuam tshuam txog cov ntsiab lus ntawmDaim tawv nqaij microbes
1. Kev sib xyaw ntawm daim tawv nqaij microbes
Skin microbes are important members of the skin ecosystem, and the flora on the skin surface can usually be divided into resident bacteria and transient bacteria. Resident bacteria are a group of microorganisms that colonize healthy skin, including Staphylococcus, Corynebacterium, Propionibacterium, Acinetobacter, Malassezia, Micrococcus, Enterobacter, and Klebsiella. Temporary bacteria refer to a class of microorganisms obtained through contact with the external environment, including Staphylococcus aureus, Streptococcus hemolyticus and Enterococcus, etc. They are the main pathogenic bacteria that cause skin infections. Cov kab mob yog cov kab mob tseem ceeb ntawm cov tawv nqaij, thiab tseem muaj cov fungi ntawm daim tawv nqaij. From the phylum level, the new drama on the skin surface is mainly composed of four phyla, namely Actinobacteria, Firmicutes, Proteobacteria and Bacteroidetes. Los ntawm cov kab mob theem, cov kab mob ntawm cov tawv nqaij saum npoo tsuas yog CondneBacterium tsuas yog CondneBacterium, Staphylococcus thiab Propionibacterium. Cov kab mob no ua lub luag haujlwm tseem ceeb hauv kev saib xyuas cov tawv nqaij.
2. Qhov xwm txheej cuam tshuam rau daim tawv nqaij microecology
(1) Tus Thawj Coj
Xws li hnub nyoog, poj niam txiv neej, qhov chaw, txhua tus muaj cov nyhuv ntawm cov tawv nqaij microbes.
(2) daim tawv nqaij
(3) sab saum toj ntawm cov tawv nqaij saum npoo.
Sab saum toj hloov ntawm daim tawv nqaij saum npoo yog raws ntawm cov cheeb tsam sib txawv hauv daim tawv nqaij anatomy. Cov txheej txheem kev coj noj coj ua kawm txoj kev kawm uas sib txawv ntawm cov cheeb tsam sib txawv txhawb cov kab mob sib txawv.
(4) lub cev
Txoj kev siv roj ntsha molecular ntes pom cov tswvyim ntawm cov kab mob sib txawv, hais txog cov microbiota yog lub cev nyob ntawm lub cev. Bacterial colonization is dependent on the physiological site of the skin and is associated with a specific moist, dry, sebaceous microenvironment, etc.
(5) lub sijhawm hloov
(6) PHEEB
(7) exogenous yam - siv tshuaj pleev ib ce
Muaj ntau yam exogenous yam uas 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. Among the many external factors, cosmetics are one of the important factors affecting the skin microecology in some parts of the human body due to the frequent contact of the skin with cosmetics.
