Tus neeg sawv cev ntawm tus kab mob diphtheria, paub zoo hauv cov tshuaj xws li Corynebacterium diphtheriae, tau tshawb pom thiab tom qab ntawd ua tiav cais tawm ntawm cov khoom noj hauv cov kab lis kev cai ntshiab 100 xyoo dhau los. Nyob rau tib lub sijhawm, tom qab ob peb xyoos ntawm kev tshawb fawb nquag, nws lub luag haujlwm hauv kev pib thiab kev loj hlob ntawm cov kab mob sib kis tau tsim. Qhov no ua tau tsuas yog tom qab tau txais cov tshuaj lom tshwj xeeb uas cov kab mob tsim. Nws ua rau kev tuag ntawm tus tsiaj sim, uas tsim cov tsos mob ntawm pathological zoo ib yam li cov uas tau pom hauv cov neeg mob diphtheria.
Tus kab mob ua rau tus kab mob diphtheria belongs rau genus Corynebacterium. Tab sis nyob rau tib lub sijhawm, nws raug xa mus rau ib pawg ntawm cov kab mob coryneform. Cov no yog me ntsis nkhaus sticks, uas muaj extensions los yog cov ntsiab lus ntawm qhov kawg. Lawv kuj muaj kev faib atypical, lawv zoo li tawg hauv ob, thaum tau txaisCov yam ntxwv kev npaj nyob rau hauv daim ntawv ntawm Latin tsab ntawv V. Tab sis nyob rau hauv lub kawm smears, ib tug kuj pom ib leeg, cais sticks. Tus kab mob ua rau tus kab mob diphtheria yog cov kab mob loj heev, nws qhov ntev mus txog 8 microns. Lawv tsis muaj flagella, lawv tsis tsim cov tshuaj tiv thaiv. Lwm yam khoom tseem ceeb ntawm tus kab mob diphtheria bacillus yog lub peev xwm tsim cov co toxins uas muaj zog heev.
Txhua hom kab mob corynebacteria yog facultative anaerobes. Lawv vam meej nrog lossis tsis muaj oxygen. Resistant rau ziab, txawm tias lawv tsis muaj spores. Yog tias cov kab lis kev cai ntshiab raug cua sov ntawm 60 degrees, nws yuav raug rhuav tshem hauv ib teev. Thiab nyob rau hauv cov ntaub ntawv pathological, uas yog, yog tias lawv muaj kev tiv thaiv cov protein, tus neeg sawv cev ntawm tus kab mob diphtheria tuaj yeem tswj hwm nws cov haujlwm tseem ceeb ntawm 40 mus rau 60 feeb. ntawm qhov kub ntawm 90 degrees. Raws li rau qhov kub thiab txias, tsis muaj kev cuam tshuam rau cov kab mob no. Ntawm qhov ib txwm muaj nyob hauv cov tshuaj tua kab mob, cov kab mob sai sai tuag.
Tus kab mob ua rau tus kab mob diphtheria kuj yog tus cwj pwm los ntawm kev mob siab polymorphism. Nws manifests nws tus kheej tsis tsuas yog nyob rau hauv kev hloov nyob rau hauv lub thickness tsis, tab sis kuj nyob rau hauv ib tug hloov nyob rau hauv cov duab nws tus kheej. Nyob rau hauv smears, branching, filiform, segmented, o thiab flask-shaped sticks yog txawv. Nyob rau tib lub sijhawm, thickening tuaj yeem pom ntawm lawv qhov kawg ntawm ob sab tom qab 12 teev txij thaum pib ntawm kab lis kev cai loj hlob, tus kab mob yuav siv daim ntawv dumbbell. Nyob rau hauv cov thickenings nrog tshwj xeebstaining nthuav tawm lub npe hu ua Babesh-Ernst nplej (pawg ntawm txiaj nplej).
kab mob khaub thuas kab mob plab yog saprophytes. Lawv yog cov microorganisms uas tas li xav tau cov organic tshuaj. Tias yog vim li cas cov khoom noj khoom haus uas siv los loj hlob no microbe hauv chav kuaj yuav tsum muaj cov amino acids nyob rau hauv nws cov muaj pes tsawg leeg. Nws tuaj yeem yog cystine, alanine, methionine, valine. Cov xov xwm xaiv rau corynebacteria yog cov uas muaj cov ntshav, ntshav, lossis ascitic kua. Raws li qhov no, Leffler's kab lis kev cai nruab nrab tau tsim thawj zaug, ua raws li Tyndall's thiab Clauberg's.
