The relationships of chest roentgenographic findings and expectorations of tubercle bacilli in their sputa were studied in 455 cases with minimal pulmonary tuberculosis. 1) The patients with culturable tubercle bacilli in their sputa had pathological findings in their chest roentgenograms more than a half of one intercostal space in exudative lesions or than 1.5 cm diameter in productive lesions. 2) As the clusters of small flecks in apex had the great posibility of conglutination and solution, the patients with apical lesions showed greater positive bacterial findings than others without apical lesions. 3) Under the chemotherapy, the cavities from which the large numbers of tubercle bacilli had been continuously eliminated were contracted and drainage bronchi had disappeared; then the expectorations of tubercle bacilli occured intermittently. When the size of cavity became lesser than 0.5 cm diameter, only a few of tubercle bacilli were found in sputum intermittently. 4) The patients with minimal pulmonary tuberculosis under the chemotherapy showed very seldom or never the progression of lesions, but the patients with exudative lesions spreading more then a half of one intercostal space or productive nodular lesions more than 1.5 cm diameter, when the chemotherapy was discontinued, showed frequently the progressions of their pulmonary lesions, without concern to bacterial findings.
