Why does Caseation occur in TB?
The caseous necrosis is the basic process of tuberculosis disease in humans. The interval from infection to tuberculin conversion is never more than 8 weeks and in general is 5 to 7 weeks (21). The onset of caseous necrosis coincides with the development of acquired immune resistance or CMI and DTH.
