Abstract:
Analysis of 483 skeletons from Arica (Chile) and review of mummy dissection records demonstrates an overall 1% prevalence rate for tuberculosis between 2000 B.C. and A.D. 1500. Tuberculosis cases cluster in the period A.D. 500-1000 which correlates with fully agropastoral societies. Considering only these agropastoral societies, about 2% of their members show tuberculosis lesions. A segment of DNA unique to Mycobacterium tuberculosis was identified in an extract from the vertebral lesion of a 12-year-old girl with Pott's disease from about A.D. 1000, establishing the pre-Columbian presence of tuberculosis with the most specific evidence currently available.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
