Amagciwane anaerobic. Life ngaphandle oksijini okumsulwa

amagciwane anaerobic ingaqala ngokungabi bikho-mpilo mahhala imvelo. Bekanye namanye amagciwane kokuba impahla nesiyingqayizivele, zingabantu isigaba anaerobes. Zimbili izinhlobo anaerobes. Njengoba facultative futhi baphoqwe anaerobic amagciwane ingatholakala cishe zonke amasampula pathologic izakhiwo ezibonakalayo, ahambisana izifo ezihlukahlukene pyo ukuvuvukala kungenzeka ezingosomathuba ngisho ngezikhathi pathogenic.

nezilwanyana ezincane anaerobic okuqondene ozikhethela akhona futhi wande oksijini, nomoya-mpilo-free imvelo. Laba bameleli be-evelele kunazo alesi sigaba E. coli, Shigella, Staphylococcus, Yersinia, streptococci nezinye amagciwane.

Baphoqwe nezilwanyana ezincane ngeke siphile ebukhoneni-mpilo khulula futhi bafe emiphumeleni yayo. Iqembu lokuqala kuleli kilasi umelwe anaerobes spore ukwakha amagciwane noma clostridia, futhi ama-bacterium yesibili musa yakha ezinhlamvu (anaerobes non-clostridial). Clostridia zivame causative ejenti izifo anaerobic of the gama elifanayo. Isibonelo kungaba clostridial izifo ukulimaza, botulism, ngqi. anaerobes Non-clostridial kukhona Gram-HIV amagciwane Gram-HIV. Ziyakwazi induku emise noma ukuma eyindilinga, ngokuqinisekile ohlangana izincwadi egameni nababamele bhá: Bacteroides, veyllonelly, fuzobakterii, peptokokki, propionibacteria, peptostreptokokki, eubacteria, nabanye.

amagciwane Non-clostridial, ingxenye enkulu yomsebenzi microflora evamile kubantu nasezilwaneni. Futhi ungakwazi iqhaza ekuthuthukiseni izinqubo ukuvuvukala. Lezi zihlanganisa peritonitis, inyumoniya, iphaphu ithumba nobuchopho, empyema, sepsis, cellulitis esifundeni maxillofacial, abezindaba otitis, njll Ukuze ngobuningi yokungenwa yizifo ezithathelwanayo, okuyinto abangela non-clostridial anaerobic amagciwane uhlobo, isici umbukiso property endogenous .. Batfutfukisa ikakhulukazi ngenxa ukumelana engezansi umzimba, okungaveza ekulimaleni, ukubanda, ukuhlinzwa, iziyaluyalu izivikeli mzimba.

Ukuze uthole incazelo yokuthi indlela ngenxa yokulondoloza anaerobic zokuphila kubalulekile ukuqonda izindlela eziyisisekelo ngawo kukhona kwezimila aerobic kanye anaerobic.

kwezimila aerobic yinqubo namachibi esekelwe ukusetshenziswa oxygen. Breathing kuholela cleavage of substrate ngaphandle zinsalela, umphumela ubizwa ukubopha abampofu abameleli amandla inorganics. Imiphumela iba yinhlanganisela yokukhandleka enamandla amandla okukhipha. Njengoba le substrates ebaluleke kakhulu emishinini yokuphefumula isenzo carbohydrate kodwa futhi amaprotheni namafutha ingagxila e inqubo emishinini yokuphefumula aerobic.

It sifana esinezinyathelo ukugeleza. Ngo inqubo yokuqala anoxic isifika ngokuqhubekayo substrate cleavage ukukhulula ama-athomu ye-hydrogen sesibopho ukuthobisa i-coenzymes. Okwesibili, esigabeni oksijini, ephelezelwa cleavage obengeziwe athomu ye-hydrogen kusukela substrate for emishinini yokuphefumula kanye namachibi ayo kancane kancane.

kwezimila anaerobic usebenzisa amagciwane anaerobic. Zisetshenziswa ngokuba namachibi of substrate zokuphefumula hhayi umoya-mpilo yamangqamuzana, kanye nohlu compounds elinomoya-mpilo. Zingase zibekwe nosawoti of sulfuric, nitric, acid carbonic. Phakathi kwezimila anaerobic ziba compounds esincishisiwe.

amagciwane anaerobic ethwele umoya njengoba yokugcina electron acceptor, umoya-mpilo alisetshenziswa, futhi ketshezi wezinto ezingaphili. Njengoba lenye ekilasini ezithile kukhona izinhlobo eziningana kwezimila anaerobic: kwezimila futhi nitrification nitrate, sulfate nesibabule umoya, 'nensimbi' umoya, umoya a carbonate, fumarate kwezimila.
