Abstract:
In performing NTM chemotherapy, particularly to mycobacterium avium-intracellulare complex (MAC) infection, we find difficulty in planning a rational protocol, and thus depend on previous experiences. We have studied retrospectively the effects of previous combination chemo-therapy cases of pulmonary MAC infections at National Tokyo Hospital. We selected 135 cases which had received the same chemotherapy continuously over six months. Having set a mean CFU of 3 times sputum culture before treatment as 100%, we calculated a six-months sequential bacillary response to a regimen and plotted the bacillary response curves. The response curves of various regimens of multidrug chemotherapy indicate that combinations of more than 3 drugs including aminoglycoside and clarithromycin are effective. The survival curve of 104 cases which could be observed over 10 years showed that median survival time is about 10 years.

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.
