Abstract:
Objective The purpose of the study was to understand the resistance status of to anti-tuberculosis drug in Yunnan province, and to provide evidence for tuberculosis (TB) control. Methods The proportional method was used in drug sensitivity test according to the guidelines recommending by WHO. Results Of 301 mycobacterial isolates, 279 (92.7%) strains were complex (MTBC) . The total drug resistance rate was 31.5% (88/279),the initial drug resistance rate of was 27.3%, and the acquired drug resistance rate was 44.3%. The drug resistance rates to INH,RFP,EMB and SM were 19.7%, 10.8%, 12.9%and 19.0%, respectively. The multi-drug resistance (MDR) rate was 9.3%. Conclusion The drug resistant rate of is still high in Yunnan province,and TB control is still a long way to go. Early detection and regular treatment should be done for MDR patients. Drug resistance monitoring as an important part of TB control programs should be regular observation and research.
