Determination about primary drug resistance in mycobacterium tuberculosis from first visit pulmonary tuberculosis type III

Objective To provide scientific basis for selectchemical--drug in treatment of Pulmonary tuberculosis.Method Using Resenbach's culturemedium, drug 92 strains form first visitpulmonary tuberculosis type ill were performed in8 kinds of drugS which were used to treatpulmonary,tuberculosis.Rewlts The drug-- resistant rates of 92mycobacterium tuberculosis strains of first visitpulmonary tuberculosis was 72.8% alxl were inturn SM 50. 0%. INH44. 6%. RFP25. 0%.EMB21. 7%. KMg. 8%, PASS. 7%,CPM4.3%, 1321TH2.2% .The drug--resistant toboth i aam 2 -kinds of drubs was 52. 2%.drug--rmistant to both H aam R was 120 sthem21 .7%.Coecluaioes The drug-- resistufit rates toS. H. R and E are higher and the measurement ofdrug-- resistant is necessary for first visit treatedI vpulmo nary tuberculosis.The drug--nsistant sthemto 1 and 2 kinds drubs is co￣nly4' andconbined chemotherapy for first visit PUlmonary issuitable.
