Anaerobic mabhakitiriya. Life pasina yakaisvonaka okisijeni

Anaerobic mabhakitiriya anogona kuva pasina rusununguko okisijeni iri zvakatipoteredza. Pamwe chete mamwe majemusi kuva akasiyana pfuma yakadaro, ndivo boka anaerobes. Kune mhando mbiri anaerobes. Sezvo facultative uye unosungira anaerobic mabhakitiriya anogona kuwanikwa zvinenge specimens ose pathologic zvokunyama zvivako, ivo pamwe nezvirwere pyo-anogumbura siyana zvingava mikana uye kunyange neapo pathogenic.

Anaerobic tusingaoneki vechigaro kune optioneel iripo uye muwande oxygen, uye okisijeni-isina ezvinhu. The kupfuura raidudzwa dzinomiririra mukirasi iyi E. coli, Shigella, anonzi Staphylococcus, Yersinia, streptococci nezvimwe utachiona.

Unosungira tusingaoneki havagoni kurarama pamberi vakasununguka okisijeni uye vanofa zvachinokonzera. Boka rokutanga mukirasi iyi anomiririrwa anaerobes spore Anoumba utachiona kana clostridia, uye wechipiri utachiona hatuzoumbiki spores (non-clostridial anaerobes). Clostridia kazhinji causative vaishandira anaerobic zvirwere zvakafanana zita. Muenzaniso chingava clostridial muchikuvadza zvirwere, zvanga zvine utachiona uhu, tetenasi. Non-clostridial anaerobes vari giremu-akanaka uye giremu negative utachiona. Ndivo tsvimbo serin'i kana idenderedzwa chimiro, nokuti chokwadi wasangana mumabhuku zita ravo chakajeka vamiririri: Bacteroides, veyllonelly, fuzobakterii, peptokokki, propionibacteria, peptostreptokokki, eubacteria, uye vamwe.

Non-clostridial noutachiona, unorema chikamu kwagara microflora muvanhu nemhuka. Vanogonawo mubasa kukura anogumbura kwendangariro. Izvi zvinosanganisira peritonitis, mabayo, zvemapapu pute uye pfungwa, empyema, sepsis, cellulitis maxillofacial nharaunda, otitis nhau, etc. For unorema kutapukirwa, anokonzera non-clostridial anaerobic bacteria mhando, maitiro zviratidzwa Zvivako zviri endogenous .. Vanokurukura kazhinji nokuda nechezasi nemishonga yacho muviri, izvo zvingaguma pakukuvara, kutonhora, kuvhiyiwa, kusagadzikana masoja emuviri.

Kuti utsanangurirwe nzira nokuda kwokuramba anaerobic upenyu zvakafanira kunzwisisa dzinokosha zvigadziriswe nawo pane Kurovedza uye anaerobic afemeruke.

Kurovedza afemeruke ndiye oxidation muitiro kunobva pakushandisa okisijeni. Kufema zvinoisa cleavage pamusoro substrate asina vakasara, mugumisiro wacho shaded varombo simba vamiririri Inorganics. Zvinoguma simba simba goho. Sezvo anokosha substrates kuti afemeruke chiito makabhohaidhiretsi asiwo mapuroteni uye mafuta zvinogona kuparadzwa nedanho Kurovedza afemeruke.

It rinoenderana vaviri-danho chokubuda. In wokutanga anoxic muitiro inoitika zvishoma substrate cleavage kusunungura hydrogen maatomu nokusungwa kune coenzymes. Chechipiri, yakachena chikuva, achiperekedzwa mamwe cleavage pakati hydrogen maatomu kubva substrate kuti afemeruke wayo zvishoma nezvishoma oxidation.

Anaerobic afemeruke uchishandisa anaerobic utachiona. Vari akashandiswa oxidation kuti kufema substrate kwete samolecular okisijeni, uye pakarongwa oxygenated yeimwe. Izvi zvingava munyu pamusoro sulfuric, nitric, carbonic acids. Munguva anaerobic afemeruke vanova kwakaderedza yeimwe.

Anaerobic utachiona akatakura mweya sezvo kwokupedzisira Erekitironi acceptor, okisijeni harishandiswi, uye inorganic fuma. Ndeve imwe kirasi kunongova anoverengeka anaerobic afemeruke: afemeruke uye nitrification nitrate, sulfate nesarufa mweya, "simbi" mweya, mweya mumwe carbonate, fumarate afemeruke.
