The lung is the major portal of entry in the majority of cases of tuberculosis (7, 12). The first contact with the organism results in few or no clinical symptoms or signs. Ordinarily the tubercle bacillus sets up a localized infection in the periphery of the lung where it has been deposited by inhalation. Body defenses appear to have little effect on the organism until the time of development of tuberculin hypersensitivity (4–6 weeks). At this time, mild fever and malaise develop, and occasionally other hypersensitivity manifestations are noted.
