Ngakho-ke, izicubu zibonisa ukuzwela okukhulu ku-mycobacteria kanye ne-toxin yazo.
Njengoba sesifinyelele emaphashini, izinduku zikaKoch kulokhu ziqala ukuthuthukisa futhi zande. Kulesi simo, njengomthetho, kutholakala izilonda ezingashadile noma eziningi, ezizungezwe ungqimba lwamaseli avikelayo omzimba omzimba. Izingosi zokuvuvukala zikhuphuka ngokushesha, futhi ngokushesha inqubo yokwelashwa ihilela izitsha ze-lymphatic nama-lymph nodes emiphakathini yamaphaphu.
Ngokuvamile, umphumela omuhle wesifo uyabonakala - ukuvuvukala kugxila ngokuzimela nokuphulukisa, kushiya ama-capsules emathanjeni axhunyiwe lapho i-calcium usawoti ifakwa ngemva kwesikhashana. Ezingxabeni ezinjalo, izintambo zeKokh zingase zihlale zingasebenzi isikhathi eside, amathuba okusebenza okuyi-10%. Ngokuvamile, i-foci ephulukisiwe itholakala kubantu abanempilo abane-X-ray ukuxilonga, okubonisa isifo esidluliselwe ngaphambili.
