I-Mycobacterium Tuberculosis DNA

I-Mycobacterium tuberculosis (Tubercle bacillus, TB) luhlobo lwebhaktiriya enyanzelekileyo ene-asidi ekhawulezayo.Kukho i-pili kwi-TB kodwa akukho flagellum.Nangona i-TB inemicrocapsules kodwa ingenzi spores.Udonga lweeseli ze-TB alunayo i-teichoic acid yebhaktiriya yegram-positive okanye i-lipopolysaccharide yebhaktiriya yegram-negative.Isifo sephepha seMycobacterium esipathogenic ebantwini sahlulwe ngokubanzi ngokohlobo lomntu, uhlobo lwenkomo, kunye nohlobo lwaseAfrika.I-pathogenicity ye-TB inokuhambelana nokudumba okubangelwa ukwanda kweebhaktheriya kwiiseli zezicubu, ubuthi bezinto zebhaktheriya kunye ne-metabolites, kunye nomonakalo womzimba kumalungu ebhaktheriya.Izinto ze-Pathogenic zihambelana nee-capsules, i-lipids kunye neeprotheni.I-Mycobacterium tuberculosis inokuhlasela abantu abathintekayo ngendlela yokuphefumla, i-digestive tract okanye umonakalo wolusu, ibangela isifo sephepha kwiintlobo ezahlukeneyo zezicubu kunye namalungu, apho isifo sephepha esibangelwa yindlela yokuphefumla.Iyenzeka kakhulu ebantwaneni, abaneempawu ezinjengomkhuhlane womgangatho ophantsi, ukubila ebusuku, kunye nenani elincinci le-hemoptysis.Usulelo lweSekondari lubonakaliswa ikakhulu njengomkhuhlane ophantsi, ukubila ebusuku, i-hemoptysis kunye nezinye iimpawu;ukuqala okungapheliyo, ukuhlaselwa okumbalwa okubukhali.Isifo sephepha sesinye sezona zizathu zilishumi ziphambili zokufa ehlabathini.Ngo-2018, malunga ne-10 yezigidi zabantu emhlabeni bosulelwe sisifo sephepha seMycobacterium, malunga ne-1.6 yezigidi zabantu ababhubhileyo.I-China lilizwe elinomthwalo ophezulu wesifo sephepha, kwaye izinga lokwenzeka kwalo likwindawo yesibini kwihlabathi.
