本文报告南非在7年间6次结核病流调中X胸片与痰培养结果的关系。5,477例同时作了痰培养及X线胸片。男性占20％,女性占80％;年龄均大于15岁。由自发咳出刺激会厌或雾化吸入盐水取得的痰标本在三天内按改良Petroff氏法处理后接种于三支培基上(L-J斜面培基二支,加5％焦葡萄糖酸钠的L-J培基一支)。凡培基上有典型的菌落形态,并经抗酸染色镜检,菸酸及亚硝酸还原试验等证实为结核菌者。计算菌落生长数目以判断其生长程度:(1)孤立一个菌落,(2)2～3个菌落,(3)+(21～99个菌落),(4)++(100～200个菌落),(5)+++(约500个菌落),(6)++++(融合状生长)。
This article reports the relationship between X-ray and sputum culture results of six tuberculosis epidemics in South Africa over a seven-year period. 5,477 cases made sputum culture and X-ray at the same time. 20% of males and 80% of females; all older than 15 years. Sputum samples obtained from spontaneous cough stimulation of epiglottis or nebulized saline were inoculated on three basal bodies within three days after treatment with the modified Petroff’s method (two LJ beveled basal bodies, 5% L-sodium pyroglutamate Base one). Where there is a typical colonies Pearles colony morphology, and by acid-fast staining microscopy, niacin and nitrite reduction test confirmed as those who are tuberculosis. Calculate the number of colonies to determine the extent of their growth: (1) Isolate one colony, (2) 2 to 3 colonies, (3) + (21 to 99 colonies), (4) ++ (100 to 200 colonies) , (5) +++ (about 500 colonies), (6) ++++ (fusiform growth).
