Iarhente causative of isifo somqala omhlophe, amayeza eyaziwa ngokuba Ezi diphtheriae, wafunyanwa, baza emva koko wachacha ngempumelelo kumajelo nezondlo kwinkcubeko olunyulu iminyaka eli-100 eyadlulayo. Ngoko, emva kweminyaka emininzi yokufunda ngokunzulu, kuye kwasekwa indima ukwenzeka nophuhliso zophendlo lwezifo usulelo. Oku kunokwenzeka kuphela emva kokuba kufunyenwe ityhefu ethile ukuba igciwane uvelisa. Ubangela nokufa kwesilwanyana uvavanyo, leyo akhiwa neempawu zophendlo lwezifo ezifana nezo eziqwalaselweyo izigulane ukubola komqala.
Ukubola komqala bobabo sodidi Ezi. Kodwa ke wabhekisela iqela eyahlukileyo iintsholongwane coryneform. Oku kujikwa kancinci iintonga ezithe ukwandisa okanye tapering kwi eziphelweni. Kwakhona bayakwazi ukwahlula Nedlac, njengokuba xa babeyigqobhozile ibe ngamaqela amabini, kunye kwindawo eyahlukileyo ngohlobo ileta Latin V. Kodwa ke smears uvavanyo iyabonakala kwaye, iintonga elise ngaphandle ekwanti. Iarhente causative of ukubola komqala - iintsholongwane elide, ubude baso microns-8. Abanalo misila,-CAPS protective ezizo. Enye impahla ebalulekileyo ukubola komqala bacilli kukukwazi ukwenza ityhefu kakhulu.
Zonke iintlobo Ezi zizinto anaerobes facultative. Bavakalelwa kakuhle zombini phambi ioksijini, kwaye ngaphandle kwayo. Ukumelana omiswe, nangona kungekho ingxabano. Xa phantsi ubushushu inkcubeko esulungekileyo degrees 60, iya ivuthu- ngexesha elinye. Kodwa izinto lwezidumbu, ngamanye amazwi ukuba babe iproteni yokhuseleko, i-arhente causative of ukubola komqala uyakwazi ukugcina ubuchule babo ukuze baphile imizuzu engama-40 ukuya kuma-60. kubushushu degrees 90. Ngokumalunga kumaqondo obushushu asezantsi, nasonasiphi na isiphumo ezonakalisayo magciwane uyabonakala. Xa eziqhelekileyo lamanani izibulali iintsholongwane kufa ngokukhawuleza.
Lwegciwane Diphtheria linophawu polymorphism enkulu. Oku kubonakala nje kuphela utshintsho Ebubanzini parameters, kodwa ekutshintsheni ifomu ngokwayo. Xa smear ukwahlula eyayizalwa,, iintonga ukudumba, iselwa-ezimile ngomsonto-like, abamnkela. Kulo mzekelo, emiphethweni zabo macala omabini emva kweeyure ezili-12 ukususela ekuqaleni kokukhula nenkcubeko ingabonwa igciwane ukuqina kuthatha uhlobo a dumbbell. Ezi thickenings e umbala ekhethekileyo ukubonakala njalo kuxokwa ingqolowa-Iintsana Ernst (ezisebenzisanayo valyutina iinkozo).
Ukubola komqala are saprophytes. Bayibiza ezo Cya ukuba sihlala sifuna into ephilayo. Kungenxa yoko le nto kusetyenziswa amajelo inkcubeko enyamekela ukulinywa eli gciwane elabhoratri kufuneka mfuneko wakhiwe asidi acid. Oku kunokuba cystine, alanine, methionine, valine. Ukhetho medium lwegciwane coryneform abo equlethe serum, igazi okanye ascites fluid. Ngokusekelwe kule, oko kuqala kuphuhliswa zizondlo medium Leffler, ilandelwe yi-bume kunye Tyndall Clauberg.
