The survey of the atypical mycobacteria that were meant as the acid-fast bacilli of human sources but differing from human tubercle bacilli, has been made for about two years mainly with the sputa of patients diagnosed as lung-tuberculosis. 1) The frequecies of isolations of these bacilli ware as follows; all patients diagnosed as lung-tuberculosis; 0.57% (17, 338 materials) in-patients; O.14 % (14, 562 materials) out-patients; 2.8% (2, 776 materials) old ages at a work house in Urawa city; O.2%(439 materials) Urawa Citizens examined by the medical survice; 3.7% (107 materials) From the out-patients and the citizens these bacilli were isolated more frequently than from the inpatints and old ages at a work house. These results seemed to sugges t that the atypical mycobacteria were more frequently isolated from men who used to live mainly outdoors than from men who used to spend a day almost indoors. 2) In this study, the acid-fast bacilli isolate d by our method included many kinds of mycobacteria, such as saprophytes. At first, these strains were divided as negatives and positives by the neutral red stanining test modified by wayne et al. The negatives were designated as "others" in this study, and the positives were classified according to pigment production. Photochromogen was not isolated in our survey. All strains classified as non-photochromogen were Battey type and were more frequently isolated from the out-patients than from the in-patients, but "others" were less frequently isolated from the out-patients than from the in-patients. The biological characteristics of these strains are tabled in table 1 and a good many of the "others" seems to be consisted of rapid growers. 3) Four patients who excreted non-photochromogen frequently or constantly for a long time without isolations of tubercle bacilli were detected in the out-patients diagnosed as lung-tuberculosis. In them, chest-roentgen ographic abnormalities were seen, showing cavities or bronchiectasis. These patients had not grown worse, in spite of excreting these bacilli constantly or a wrong drugtreatment. From these facts, it is not clear whether these bacilli were pathogens or members of normally existing acid-fast saprophytes.
