Present Status of Tuberculosis among Inhabitants of Amami-Islands. 3 rd Report. Results of Bacteriological Examination

Abstract

Bacteriological examination was made on all cases, to whom radiography was indicated according to the results of miniature X-ray findings and tuberculin reaction in the tuberculosis mass surveys carried out in Okierabu-island (1961) and Setouchi-town (1962). The majority of the specimens examined was laryngeal swab and a few cases was examined by sputum. These specimens were kept in an icebox and each specimen was cultured on three slants of 1% Ogawa's egg media after pretreatment with 4% NaOH on the same day. Then, the slants were kept in an incubator at 37°C and observed for 8weeks. All of the acid-fast bacilli were investigated on their biological characteristics. Drug resistance was tested by the indirect test method on the strains which were identified as human type tubercle bacilli. © 1963, JAPANESE SOCIETY FOR TUBERCULOSIS. All rights reserved.
