Mycobacterium tuberculosis There has been a remarkable resurgence of tuberculosis in Western countries, due in large part to not only AIDS population, but also institutional overcrowding and immigrant populations. Tuberculosis also remains common in developing countries. Gastrointestinal tuberculosis may be acquired through several mechanisms, including the swallowing of infected sputum in pulmonary tuberculosis, ingestion of contaminated milk (rare where pasteurization is common), via hematogenous spread from pulmonary or military disease, and direct extension from adjacent organs.
