Ukwakheka kanye Nezici EzithonyayoAmagciwane Esikhumba
1. Ukwakheka kwamagciwane esikhumba
Ama-microbes esikhumba angamalungu abalulekile ohlelweni lwesikhumba, futhi izitshalo ezisebusweni besikhumba ngokuvamile zingahlukaniswa zibe ama-bacteria ahlalayo kanye nama-bacteria adlulayo. Ama-bacteria ahlalayo yiqembu lama-microbes ahlala esikhumbeni esinempilo, okuhlanganisa i-Staphylococcus, i-Corynebacterium, i-Propionibacterium, i-Acinetobacter, i-Malassezia, i-Micrococcus, i-Enterobacter, kanye ne-Klebsiella. Ama-bacteria esikhashana abhekisela ekilasini lama-microbes atholakala ngokuxhumana nendawo engaphandle, okuhlanganisa i-Staphylococcus aureus, i-Streptococcus hemolyticus kanye ne-Enterococcus, njll. Angama-bacteria abangela izifo ayinhloko abangela ukutheleleka kwesikhumba. Ama-bacteria angama-bacteria ahamba phambili ebusweni besikhumba, futhi kukhona ne-fungi esikhumbeni. Kusukela ezingeni le-phylum, idrama entsha ebusweni besikhumba yakhiwe kakhulu ama-phyla amane, okuyi-Actinobacteria, i-Firmicutes, i-Proteobacteria kanye ne-Bacteroidetes. Kusukela ezingeni lohlobo, ama-bacteria asebusweni besikhumba ikakhulukazi yi-Corynebacterium, i-Staphylococcus kanye ne-Propionibacterium. Lawa ma-bacteria adlala indima enkulu ekugcineni impilo yesikhumba.
2. Izici ezithinta i-microecology yesikhumba
(1) Isici somsingathi
Njengobudala, ubulili, indawo, konke kunomthelela kuma-microbes esikhumba.
(2) Izithako zesikhumba
Ukungena kanye nezitho zesikhumba, okuhlanganisa nezindlala zokujuluka (izindlala zokujuluka kanye ne-apocrine), izindlala ze-sebaceous, kanye nezimbotshana zezinwele, zinezitshalo zazo ezihlukile.
(3) Ukuma kwendawo yesikhumba.
Izinguquko zesimo sesikhumba zisekelwe ekwehlukeni kwesifunda kwesimo sesikhumba. Izindlela ezisekelwe esikweni zihlola ukuthi izindawo ezahlukene zesimo sesikhumba zisekela ama-microorganisms ahlukene.
(4) Izingxenye zomzimba
Izindlela zebhayoloji zama-molecule zibona umqondo wokuhlukahluka kwamagciwane, zigcizelela ukuthi i-microbiota yesikhumba incike endaweni yomzimba. Ukwakheka kwamagciwane kuncike endaweni yomzimba yesikhumba futhi kuhlotshaniswa nendawo ethile emanzi, eyomile, ne-sebaceous microenvironment, njll.
(5) Ukushintsha kwesikhathi
Izindlela zebhayoloji zama-molecule zasetshenziswa ukutadisha izinguquko zesikhashana nezendawo ze-skin microbiota, okwatholakala ukuthi zihlobene nesikhathi nendawo yokuthathwa kwesampula.
(6) ushintsho lwe-pH
Kusukela ngo-1929, uMarchionini wafakazela ukuthi isikhumba sine-asidi, ngaleyo ndlela wasungula umqondo wokuthi isikhumba “sine-countercoat” engavimbela ukukhula kwamagciwane futhi ivikele umzimba ekuthelelekeni, okuye kwasetshenziswa ocwaningweni lwesikhumba kuze kube namuhla.
(7) Izinto zangaphandle – ukusetshenziswa kwezimonyo
Kunezici eziningi zangaphandle ezithintai-microecology yesikhumba, njengokushisa, umswakama, ikhwalithi yomoya, izimonyo, njll. zendawo engaphandle. Phakathi kwezici eziningi zangaphandle, izimonyo zingenye yezinto ezibalulekile ezithinta i-microecology yesikhumba kwezinye izingxenye zomzimba womuntu ngenxa yokuxhumana njalo kwesikhumba nezimonyo.
