Ukwakhiwa kunye nezinto ezichaphazelayoIintsholongwane zolusu
1. Ukwakheka kweentsholongwane zesikhumba
Iintsholongwane zesikhumba zingamalungu abalulekileyo kwi-ecosystem yesikhumba, kwaye izityalo ezikumphezulu wesikhumba zihlala zahlulwe zibe ziintsholongwane ezihlala kunye neentsholongwane ezidlulayo. Iintsholongwane ezihlala liqela leentsholongwane ezihlala kulusu olusempilweni, kuquka iStaphylococcus, iCorynebacterium, iPropionibacterium, iAcinetobacter, iMalassezia, iMicrococcus, iEnterobacter, kunye neKlebsiella. Iintsholongwane zexeshana zibhekisa kudidi lweentsholongwane ezifunyanwa ngokudibana nokusingqongileyo kwangaphandle, kuquka iStaphylococcus aureus, iStreptococcus hemolyticus kunye neEnterococcus, njl. Ziintsholongwane eziphambili ezibangela usulelo lolusu. Iintsholongwane zezona ntsholongwane zibalaseleyo kumphezulu wesikhumba, kwaye kukwakho neefungi kulusu. Ukusuka kwinqanaba le-phylum, idrama entsha kumphezulu wesikhumba yenziwe ikakhulu zii-phyla ezine, ezizezi i-Actinobacteria, iFirmicutes, iProteobacteria kunye neBacteroidetes. Ukusuka kwinqanaba le-genus, iintsholongwane ezikumphezulu wesikhumba ikakhulu yiCorynebacterium, iStaphylococcus kunye nePropionibacterium. Ezi ntsholongwane zidlala indima enkulu ekugcineni impilo yesikhumba.
2. Izinto ezichaphazela i-microecology yolusu
(1) Into yokubamba
Njengobudala, isini, indawo, zonke ezi zinto zinefuthe kwiintsholongwane zesikhumba.
(2) Izithako zolusu
Ukungena kunye nezitho zomzimba eluswini, kuquka amadlala okubila (amadlala okubila kunye namadlala e-apocrine), amadlala e-sebaceous, kunye ne-hair follicles, zinezityalo zazo ezikhethekileyo.
(3) Inkcazo-mhlaba yomphezulu wolusu.
Utshintsho lwendawo yolusu lusekelwe kumahluko wengingqi kwindlela olukhula ngayo ulusu. Iindlela ezisekelwe kwinkcubeko zihlola ukuba iindawo ezahlukeneyo zendawo zixhasa iintsholongwane ezahlukeneyo.
(4) Amalungu omzimba
Iindlela zebhayoloji zemolekyuli zifumanisa ingcamango yokwahluka kweebhaktheriya, zigxininisa ukuba i-microbiota yesikhumba ixhomekeke kwindawo yomzimba. Ukudibana kweebhaktheriya kuxhomekeke kwindawo yempilo yesikhumba kwaye kunxulunyaniswa nendawo ethile emanzi, eyomileyo, neyomileyo, njl.
(5) Utshintsho lwexesha
Iindlela zebhayoloji zemolekyuli zisetyenzisiwe ukufunda utshintsho lwexesha kunye nolwendawo lwe-skin microbiota, ezifunyenwe zinxulumene nexesha kunye nendawo yokuthathwa kwesampuli.
(6) utshintsho lwe-pH
Kwangowe-1929, uMarchionini wabonisa ukuba ulusu lune-asidi, ngaloo ndlela eseka ingcamango yokuba ulusu lune-"countercoat" enokuthintela ukukhula kweentsholongwane kwaye ikhusele umzimba kwizifo, nto leyo eye yasetyenziswa kuphando lwesikhumba nanamhlanje.
(7) Izinto ezingaphandle – ukusetyenziswa kwezithambiso
Kukho izinto ezininzi zangaphandle ezichaphazelai-microecology yolusu, njengobushushu, ukufuma, umgangatho womoya, izinto zokuthambisa, njl.njl. zokusingqongileyo kwangaphandle. Phakathi kwezinto ezininzi zangaphandle, izinto zokuthambisa zezinye zezinto ezibalulekileyo ezichaphazela i-microecology yolusu kwiindawo ezithile zomzimba womntu ngenxa yokudibana rhoqo kolusu nezinto zokuthambisa.
