For each of the features of tuberculous infection listed on the left select the most appropriate association from those on the right

The answer is E, D, B. Caseous material may liquefy following invasion by polymorphs to produce tuberculous pus; this occurs in kidneys and bone and may extend into soft tissues.

Spread by the blood stream occurs in miliary TB and organs affected contain multiple small (1-2 mm) white nodules (miliary tubercles) which undergo caseous necrosis.

Initial infection produces the primary lesion, i.e., in lung (A) which remains small, but bacteria spread to the regional lymph nodes to form the primary complex of primary lesions plus involved regional lymph nodes. Scar tissue with calcification (C) is a common result of healing of tuberculosis.
