The causative mutumwa diphtheria, mukurapa inozivikanwa Corynebacterium diphtheriae, wakawanikwa, uye ipapo zvinobudirira akapora pamusoro inotonhorera vezvenhau wakachena mutsika makore 100 apfuura. Zvadaro, pashure pemakore ndichibvunza kudzidza, hazvina hwakagadzwa basa kuwanikwa uye kukura pathological noutachiona. Izvi zvaibvira chete pashure risiti zvimwe toxin kuti utachiona unobereka. Anoita rufu experimental mhuka, iyo inoumbwa pathological zviratidzo zvakafanana avo kuchengetwa varwere diphtheria.
Diphtheria runobva kuna genus Corynebacterium. Asi iye raireva yoga boka coryneform mabhakitiriya. Zvinonzi curved zvishoma tsvimbo kuti vave kuwedzera kana tapering mativi. Vanonzwawo atypical nokupesana, sokunge vari yarega migove miviri, ane nevamwe nzvimbo iri muchimiro rechiLatin tsamba V. Asi bvunzo smears zvinogona kuonekwa uye yoga, kunze riri zvimiti. The causative nomumiririri diphtheria - utachiona vanganzi guru, kureba kwarwo 8 microns. Havana flagella, unodzivirira nguwani hatuzoumbiki. Chimwe chinokosha pfuma diphtheria bacilli kukwanisa kuumba zvinokachidza simba kwazvo.
Ose Corynebacterium vari facultative anaerobes. Vanonzwa zvakanaka zvose pamberi okisijeni, uye pasina izvozvo. Husingakwanisi nokuomesa, kunyange vasina nharo. Kana pasi kupisa kwezuva yakachena tsika 60 inegumi, izvozvo kuchaparara panguva awa rimwe. Asi pathological zvinhu, i.e. kana vane dziviriro mapuroteni, ari causative Mutumwa diphtheria kuramba kugona kwavo kuti vararame 40 kusvika 60 maminitsi. panguva tembiricha rworwendo 90. Panyaya yakaderera tembiricha chero tigume pamusoro tusingaoneki iri kuchengetwa. Chaiye kuwanda mishonga yokuuraya utachiona utachiona kufa nokukurumidza.
Utachiona hwakakura Diphtheria chiri dzinoratidzwa guru polymorphism. Kunoratidza pacharo kwete chete nokuchinja pakukora pakati parameters, asiwo kuchinja chimiro pachayo. In smears kusiyanisa branching,, kuzvimba uye chinu-zvakaumbwa tsotso shinda-zvakadai, segmented. Muchiitiko chino, pane mativi avo pamativi ose pashure maawa 12 kubva pakutanga tsika kukura kunogona kuonekwa thickening utachiona anotora chimiro dumbbell. thickenings izvi panguva chaiyo ruvara dzakaonekwa atumidzwa zviyo-Vacheche Ernst (valyutina zviyo masumbu).
Diphtheria muri saprophytes. Ivo vanotaura avo tusingaoneki kuti vanongogara vachida makemikari nyaya. Ndokusaka vakashandisa tsika vezvenhau kuti kurima microbe ichi murabhoritari vanofanira hazvo kuva riine amino acids. Izvi zvingava cystine, alanine, methionine, valine. Selection svikiro nokuti coryneform bacteria vaya zvine serum, ropa kana ascites Urume. Kubva musi uyu, kuigadzira yakazokudziridzwa inotonhorera svikiro Leffler, zvichiteverwa zvakatipoteredza uye Tyndall Clauberg.
