Recently we found that distilled water in sickroom of pulmonary tuberculosis was heavily contaminated with acid-fast bacteria and much acid-fast bacteria were isolated from gargled water of many patients, So we investigated the distribution of acid-fast bacteria in hospital, and found that much acidfast bacteria exist in flower-vase-water, distilled water and water in incubater. These acid-fast bacteria isolated from water were identified all as M. aquae. M. aquae truly isolated from respiratory tract were investigated, and its pathogenicity also was discussed.
