Mhedzisiro yekudzivirira yeGanda micrEcologypaganda
Iyo sebaceous glands secrete Lipids, iyo iri metabolized ne microorganisms kuti iite inoyevedza lipid firimu. Iyi mafirimu emifananidzo ane mahara mafuta eakanaka, anozivikanwawo seaya mafirimu emari, ayo anogona kusarerekera maAlkaline zvinhu zvakasvibiswa paganda uye achitsvaga mabhakitiriya ekunze (achipfuura mabhakitiriya). , Fungi nevamwe uye humwe hutachiona hwechipatorms vanokura, saka basa rekutanga reiyo yakajairika ganda flora imhedzisiro yakakosha.
Kusungwa kweganda uye zvisviniro, kusanganisira ziya ziya Iyo sebaceous glands inobatanidza iyo bvudzi mavara kuti aumbe iyo follicular sebaceous unit, iyo inosimbisa chinhu chakapfuma lipic chinonzi sebum. Sebum in the hydrophobic firimu inodzivirira uye inodonhedza ganda nebvudzi uye zviito seyenzi yemidhiya. Iyo sebaceous glands ndeye hypoxic, inotsigira kukura kwekisimusi yeaErobic bacteria yakadai seP. Acnes, iyo ine p. acnes lipase iyo degrades sebum, hydrolyzes triglycerides mu sebum, uye inoburitsa mahara mafuta ecids. Buttia inogona kuomerera kune aya mahara mafuta ecids, iyo inobatsira kutsanangura colonical yeSebaceous Glass na P. Acnes, uye aya Mahara Fatty Acids zvakare anopa kune iyo acidity yeganda (pH ye5). Vazhinji vakajairwa pathogenic bactia, senge staphyloccus auseus uye straptocccus Pyogene, saka vanofarira kukura kweCogulasese-isina kunaka staphylocci uye cryneform bactia. Nekudaro, occlussion yeganda inozoguma nekuwedzera muPH iyo ichafarira kukura kweS. Aureus naSc. Pyogene. Nekuti vanhu vanogadzira mamwe mashopu anokona pane dzimwe mhuka, more P. acnes colonizer ganda revanhu.
