I-Mycobacterium Tuberculosis DNA

I-MyCobacterium Tuberculosis (Tubercle bacillus, TB) uhlobo lwamagciwane e-odolobic e-aerobic anamabala amahle ane-acid. Kukhona i-pili ku-TB kepha akukho flagellum. Yize i-TB inama-microcapsops kepha ayivezi izinhlamvu. Udonga lweseli lwe-TB alunayo i-teichooic acid yama-bacterium ane-gram - ama-lipopoliyaccharide ama-gram-amagciwane angenayo. Isifo sofuba i-Mycobacterium okuyi-pathogenic kubantu ngokuvamile ihlukaniswe ngohlobo lomuntu, uhlobo lwe-bovine, nohlobo lwase-Afrika. I-pathogenicicity ye-TB ingahle ihambisane nokuvuvukala okubangelwa ukwanda kwamagciwane kuma-rush cell, ubuthi bezakhi zamagciwane kanye nama-metabolites, kanye nokulimala komzimba ezintweni ezinamagciwane. Izinto ze-pathogenic zihlobene nama-capsule, ama-lipid namaprotheni. I-MyCobacterium Tuberculosis ingahlasela inani labantu ngokutholwa ngepheshana lokuphefumula, ukulimala kokugayanisa noma ukulimala kwesikhumba, okubangela isifo sofuba ezindaweni ezahlukahlukene kanye nezithonjana ezibangelwa yilesi sigqoko sokuphefumula kakhulu. Kwenzeka kakhulu ezinganeni, ngezimpawu ezifana nomkhuhlane webanga eliphansi, izithukuthuku zasebusuku, nenani elincane le-hemoptysis. Izifo zesibili zibonakaliswa ikakhulukazi njengomkhuhlane webanga eliphansi, izithukuthuku zasebusuku, hemoptysis nezinye izimpawu; Ukuqala okungamahlalakhona, ukuhlaselwa okumbalwa okunzima. Isifo sofuba kungenye yezimbangela eziyishumi eziholela ekufeni emhlabeni. Ngo-2018, abantu ababalelwa ezigidini eziyishumi emhlabeni batheleleke nge-Mycobacterium Tuberculosis, babalelwa ezigidini eziyi-1,6 abantu. I-China yizwe elinomthwalo omkhulu wesifo sofuba, kanye nezinga laso lesimo sezehlakalo ezisesibili emhlabeni.
